Preparation of labeled staphylococcal enterotoxin A with high specific activity. (1/237)Staphylococcal enterotoxin A (SEA) was labeled by the chloramine-T method with 125I to a specific activity of 68 to 300 muCi per mug of SEA and with 131I to specific activity of 8 to 218 muCi per mug of SEA. SEA was partially damaged and aggregated during the labeling and storage. The damage seemed not to be greatly dependent on the specific activity of labeled entertoxin. Crossed immunoelectrophoresis showed two antigenically active and three inactive components in the ascending part of the labeled enterotoxin peak during fractionation by gel chromatography. During storage at 4 degrees C, the antigenic activity of label decreased faster when labeling had been with 131I than when with 125I. The antigenic activity of labeled SEA was lowered remarkably in the ascending part of the protein peak. Greatest release of radioiodine during storage was in the same part of protein peak. According to these results, the most suitable label for radioimmunoassay is obtained from the descending part of protein peak. (+info)
Secondary radicals derived from chloramines of apolipoprotein B-100 contribute to HOCl-induced lipid peroxidation of low-density lipoproteins. (2/237)Oxidation of low-density lipoproteins (LDL) is thought to contribute to atherogenesis. Although there is increasing evidence for a role of myeloperoxidase-derived oxidants such as hypochlorite (HOCl), the mechanism by which HOCl modifies LDL remains controversial. Some studies report the protein component to be the major site of attack, whereas others describe extensive lipid peroxidation. The present study addresses this controversy. The results obtained are consistent with the hypothesis that radical-induced oxidation of LDL's lipids by HOCl is a secondary reaction, with most HOCl consumed via rapid, non-radical reaction with apolipoprotein B-100. Subsequent incubation of HOCl-treated LDL gives rise to lipid peroxidation and antioxidant consumption in a time-dependent manner. Similarly, with myeloperoxidase/H2O2/Cl- (the source of HOCl in vivo), protein oxidation is rapid and followed by an extended period of lipid peroxidation during which further protein oxidation does not occur. The secondary lipid peroxidation process involves EPR-detectable radicals, is attenuated by a radical trap or treatment of HOCl-oxidized LDL with methionine, and occurs less rapidly when the lipoprotein was depleted of alpha-tocopherol. The initial reaction of low concentrations of HOCl (400-fold or 800-fold molar excess) with LDL therefore seems to occur primarily by two-electron reactions with side-chain sites on apolipoprotein B-100. Some of the initial reaction products, identified as lysine-residue-derived chloramines, subsequently undergo homolytic (one-electron) reactions to give radicals that initiate antioxidant consumption and lipid oxidation via tocopherol-mediated peroxidation. The identification of these chloramines, and the radicals derived from them, as initiating agents in LDL lipid peroxidation offers potential new targets for antioxidative therapy in atherogenesis.

Hypochlorite-induced oxidation of proteins in plasma: formation of chloramines and nitrogen-centred radicals and their role in protein fragmentation. (3/237)Activated phagocyte cells generate hypochlorite (HOCl) via the release of H2O2 and the enzyme myeloperoxidase. Plasma proteins are major targets for HOCl, although little information is available about the mechanism(s) of oxidation. In this study the reaction of HOCl (at least 50 microM) with diluted fresh human plasma has been shown to generate material that oxidizes 5-thio-2-nitrobenzoic acid; these oxidants are believed to be chloramines formed from the reaction of HOCl with protein amine groups. Chloramines have also been detected with isolated plasma proteins treated with HOCl. In both cases chloramine formation accounts for approx. 20-30% of the added HOCl. These chloramines decompose in a time-dependent manner when incubated at 20 or 37 degrees C but not at 4 degrees C. Ascorbate and urate remove these chloramines in a time- and concentration-dependent manner, with the former being more efficient. The reaction of fresh diluted plasma with HOCl also gives rise to protein-derived nitrogen-centred radicals in a time- and HOCl-concentration-dependent manner; these have been detected by EPR spin trapping. Identical radicals have been detected with isolated HOCl-treated plasma proteins. Radical formation was inhibited by excess methionine, implicating protein-derived chloramines (probably from lysine side chains) as the radical source. Plasma protein fragmentation occurs in a time- and HOCl-concentration-dependent manner, as evidenced by the increased mobility of the EPR spin adducts, the detection of further radical species believed to be intermediates in protein degradation and the loss of the parent protein bands on SDS/PAGE. Fragmentation can be inhibited by methionine and other agents (ascorbate, urate, Trolox C or GSH) capable of removing chloramines and reactive radicals. These results are consistent with protein-derived chloramines, and the radicals derived from them, as contributing agents in HOCl-induced plasma protein oxidation. (+info)
Chloramine-induced haemolysis presenting as erythropoietin resistance. (4/237)BACKGROUND: In December 1996 we identified an outbreak of erythropoietin (rHuEpo) resistance requiring a substantial increase in rHuEpo dosage in one of our four haemodialysis (HD) units. The dialysate chloramine levels in this unit had risen from <0.1 p.p.m. in 1996 to 0.25-0.3 p.p.m. in 1997. In the other three HD units levels remained <0.1 p.p.m. Other parameters of water quality were within accepted standards. METHODS: Monthly records of haemoglobin level and rHuEpo dose were available for 148 patients between January 1996 and May 1998. Seventy-two patients, with no recognized cause of rHuEpo resistance, were analysed in detail (August 1997 to April 1998). A subgroup of 15 patients was examined for evidence of haemolysis during HD (methaemoglobin and haptoglobin levels, reticulocyte counts and Heinz bodies). Larger carbon columns were installed in December 1997 to effect chloramine removal. RESULTS: There was an increase in mean methaemoglobinaemia of 23% (P<0.01) and a 21% fall in mean haptoglobin (P<0.01) across HD, although no patient had a reticulocytosis and only one patient with G6PD deficiency had Heinz bodies. Following installation of larger carbon columns there was an 18.6% rise (P<0.001) in mean haemoglobin level and a subsequent 25.0% reduction (P<0.001) in mean rHuEpo dose. Intradialytic changes in methaemoglobin and haptoglobin were abolished. The dialysate chloramine levels fell to < 0.1 p.p.m. Water company records subsequently revealed a sustained twofold increase in mains water chloramine from November 1996. CONCLUSIONS: This is the first report linking chloramine exposure and rHuEpo resistance, with only subtle signs of haemolysis. Unheralded changes in mains water constituents can directly affect dialysate water quality and clinical outcomes. (+info)
Natural antioxidant, chlorogenic acid, protects against DNA breakage caused by monochloramine. (5/237)Chlorogenic acid prevented a stepwise conversion of plasmid pUC18 DNA, from I-->form II-->form III, induced by 3 mM monochloramine with a half inhibition of 67.4 microM. Chlorogenic acid reacted with monochloramine in a time-dependent manner, and the reaction rate increased with decreasing pH. These results suggest that chlorogenic acid prevents genotoxicity of monochloramine in gastric mucosa. (+info)
Monochloramine enhances Fas (APO-1/CD95)-induced apoptosis in Jurkat T cells. (6/237)Monochloramine derivatives are physiological oxidants produced by activated neutrophils. We report the effects of chemically prepared monochloramine (NH2Cl) on Fas-induced apoptosis in Jurkat T cells. When the cells were pretreated with NH2Cl (20-70 microM), subsequent addition of apoptosis-inducing anti-Fas antibody resulted in a synergistic enhancement of apoptosis. Treatment of NH2Cl (50-70 microM) alone resulted in a slight but definite apoptosis. Caspase activities, as measured by DEVD and IETD cleavage activities, were also elevated synergistically by NH2Cl + anti-Fas antibody stimulation. Moreover, a broad caspase inhibitor, Z-VAD-fmk, almost completely inhibited the apoptosis induced by NH2Cl and/or anti-Fas antibody. Fas expression on the Jurkat cell surface was not affected by the NH2Cl treatment. After 3 h of NH2Cl treatment, when the apoptosis was beginning to increase, the cells showed cytochrome c release from mitochondria, proteolytic activation of caspase 9, and poly (ADP-ribose) polymerase cleavage, regardless of Fas stimulation. Z-VAD-fmk almost completely inhibited this poly (ADP-ribose) polymerase cleavage, but not cytochrome c release. By contrast, Fas stimulation alone resulted in neither cytochrome c release nor caspase 9 activation at 3 h, and the increase in the DEVD cleavage activity and apoptosis became evident at later time points. These results suggested that NH2Cl enhanced Fas-induced apoptosis through the cytochrome c release and caspase 9 activation at the early stage of apoptosis. Chloramines derived from acute inflammation may modify immune reactions, such as cell-mediated cytotoxicity and some autoimmune diseases, by the enhancement of Fas-induced apoptosis. (+info)
Vitamin C protects against and reverses specific hypochlorous acid- and chloramine-dependent modifications of low-density lipoprotein. (7/237)Activated phagocytes produce the highly reactive oxidant hypochlorous acid (HOCl) via the myeloperoxidase-catalysed reaction of hydrogen peroxide with chloride ions. HOCl reacts readily with a number of susceptible targets on apolipoprotein B-100 of low-density lipoprotein (LDL), resulting in uncontrolled uptake of HOCl-modified LDL by macrophages. We have investigated the effects of vitamin C (ascorbate), an effective water-soluble antioxidant, on the HOCl- and chloramine-dependent modification of LDL. Co-incubation of vitamin C (25-200 microM) with LDL resulted in concentration-dependent protection against HOCl (25-200 microM)-mediated oxidation of tryptophan and lysine residues, formation of chloramines and increases in the relative electrophoretic mobility of LDL. Vitamin C also partially protected against oxidation of cysteine residues by HOCl, and fully protected against oxidation of these residues by the low-molecular-mass chloramines, N(alpha)-acetyl-lysine chloramine and taurine chloramine, and to a lesser extent monochloramine (each at 25-200 microM). Further, we found that HOCl (25-200 microM)-dependent formation of chloramines on apolipoprotein B-100 was fully reversed by 200 microM vitamin C; however, the loss of lysine residues and increase in relative electrophoretic mobility of LDL were only partially reversed, and the loss of tryptophan and cysteine residues was not reversed. Time-course experiments showed that the reversal by vitamin C of HOCl-dependent modifications became less efficient as the LDL was incubated for up to 4 h at 37 degrees C. These data show that vitamin C not only protects against, but also reverses, specific HOCl- and chloramine-dependent modifications of LDL. As HOCl-mediated LDL modifications have been strongly implicated in the pathogenesis of atherosclerosis, our data indicate that vitamin C could contribute to the anti-atherogenic defence against HOCl.

[(125)I]-GR231118: a high affinity radioligand to investigate neuropeptide Y Y(1) and Y(4) receptors. (8/237)GR231118 (also known as 1229U91 and GW1229), a purported Y(1) antagonist and Y(4) agonist was radiolabelled using the chloramine T method. [(125)I]-GR231118 binding reached equilibrium within 10 min at room temperature and remained stable for at least 4 h. Saturation binding experiments showed that [(125)I]-GR231118 binds with very high affinity (K(d) of 0.09 - 0.24 nM) in transfected HEK293 cells with the rat Y(1) and Y(4) receptor cDNA and in rat brain membrane homogenates. No specific binding sites could be detected in HEK293 cells transfected with the rat Y(2) or Y(5) receptor cDNA demonstrating the absence of significant affinity of GR231118 for these two receptor classes. Competition binding experiments revealed that specific [(125)I]-GR231118 binding in rat brain homogenates is most similar to that observed in HEK293 cells transfected with the rat Y(1), but not rat Y(4), receptor cDNA. Autoradiographic studies demonstrated that [(125)I]-GR231118 binding sites were fully inhibited by the Y(1) antagonist BIBO3304 in most areas of the rat brain. Interestingly, high percentage of [(125)I]-GR231118/BIBO3304-insensitive binding sites were detected in few areas. These [(125)I]-GR231118/BIBO3304-insensitive binding sites likely represent labelling to the Y(4) receptor subtype. In summary, [(125)I]-GR231118 is a new radiolabelled probe to investigate the Y(1) and Y(4) receptors; its major advantage being its high affinity. Using highly selective Y(1) antagonists such as BIBO3304 or BIBP3226 it is possible to block the binding of [(125)I]-GR231118 to the Y(1) receptor allowing for the characterization and visualization of the purported Y(4) subtype.

In its assessment of chloramine toxicity to marine invertebrates, Environment Canada (the Canadian equivalent of the United States Environmental Protection Agency, EPA) determined the Estimated No-Effects Value (ENEV) based on this type of data to be 0.002 ppm-Cl for marine and estuarine environments.. How much chloramine should one allow into an aquarium? That, of course, depends on what is in the aquarium. In the absence of knowing the toxicity of chloramine to every inhabitant of the aquarium (or of even knowing the identity of every inhabitant), it seems prudent to have chloramine levels far below those where the most sensitive organisms are killed, and that chloramine concentration is somewhere well below 0.005 ppm-Cl. The value suggested by Environment Canada seems like a reasonable maximum. There is, however, substantial uncertainty in deciding exactly which levels are acceptable and which are not, since there is so little data available. Perhaps the acceptable levels for daily exposures ...

The reaction of monochloramine and hydroxylamine: implications for ammonia-oxidizing bacteria in chloraminated drinking water |...
Drinking water chloramine use may promote ammonia-oxidizing bacteria (AOB) growth because of naturally occurring ammonia, residual ammonia remaining from chloramine formation, and ammonia released from chloramine decay and demand. A rapid chloramine residual loss is often associated with the onset of nitrification that may result in noncompliance with existing regulations; therefore, understanding nitrification and its control in drinking water is of practical importance. For biological ammonia oxidation (1st nitrification step), AOB use two enzymes in two consecutive reactions: (1) ammonia monooxygenase (AMO) catalyzes ammonia oxidation to hydroxylamine and (2) hydroxylamine oxidoreductase catalyzes hydroxylamine oxidation to nitrite, supplying electrons back to AMO for ammonia oxidation. Chloramine also inactivates AOB but rates vary, depending on inactivation criterion (metabolic activity, culturability, cell membrane integrity). One mechanism for the fastest inactivation (metabolic activity ...
Chloramination is the treatment of drinking water with a chloramine disinfectant. Both chlorine and small amounts of ammonia are added to the water one at a time which react together to form chloramine (also called combined chlorine), a long lasting disinfectant. Chloramine disinfection is used in both small and large water treatment plants. In the United States, the maintenance of what is called a "residual" of disinfectant that stays in the water distribution system while it is delivered to peoples homes is required by the Environmental Protection Agency (EPA). The EPA regulations give two choices for disinfectant residual - chlorine or chloramine. Many major water agencies are changing to chloramine to better meet current and anticipated federal drinking water regulations and to protect the public health. There are many similarities between chlorine and chloramine. Both provide effective residual disinfection with minimal risk to public health. Both are toxic to fish and amphibians. Both ...

Fluid debate: Citizens press experts on chloramine in water | The Hook - Charlottesville's weekly newspaper, news magazine
The Authoritys 2011 decision to use chloramines, a mixture of chlorine and ammonia responsible for massive lead-leaching in Washington, D.C. and skyrocketing levels of lead in children there, initially flew under the radar, and even some of those who granted approval, like Albemarle Supervisor Ken Boyd, say they werent aware of the hazardous side effects experienced in other communities. Hence the Thursday night public forum more than a year later.. Spotted among the crowd at Lane Auditorium were Boyd and fellow supes Duane Snow, Ann Mallek, and Dennis Rooker, and city councilors Dave Norris, Kathy Galvin, and Mayor Satyendra Huja. Those elected bodies will receive public comment in July in a joint meeting with the two water authorities- RWSA and Albemarle County Service Authority.. Rivanna chair Mike Gaffney noted that recently-tightened Environmental Protection Agency requirements were the impetus to add chloramines to local drinking water as a secondary disinfectant. He pointed out that 5.7 ...

Chloramine use is widespread in U.S. drinking water distribution systems as a secondary disinfectant. About 30% of surface water treatment plants currently use chloramines and the percentage of surface water treatment plants using chloramines might rise to as high as 40‒65% in the near future. While beneficial for controlling regulated disinfectant-by-product formation, water utilities using chloramines as a disinfectant are often challenged by nitrification in their distribution systems. This Webcast will help water utility managers and operators develop nitrification management plans and provide real-world examples from two utilities that have successfully managed nitrification in their distribution systems ...
IDEALS @ Illinois: Structural effects of chloraminated seawater on the SW30HR reverse osmosis membrane
There is a need for a more comprehensive understanding of how disinfectants, applied to control biofouling of reverse osmosis (RO) membranes, react with the polymeric active layer and affect membrane performance as a result. This work investigates structural and performance changes to the SW30HR RO membrane exposed to seawater disinfected with monochloramine. Batch experiments with RO membranes were conducted to determine the effect of secondary oxidizing agents formed from the reactions of monochloramine with bromide and iodide on membrane structure. Membrane coupons were exposed to varying concentrations of monochloramine (2, 20 and 200 mg/L as Cl2) in synthetic seawater containing proportional levels of bromide (65, 650 and 6,500 mg/L) and iodide (0.06, 0.6 and 6 mg/L) and various contact times to achieve target exposures. Batch experiments also exposed membranes to real seawater treated with monochloramine (2 mg/L as Cl2) for 68 days. Rutherford back-scattering spectrometry (RBS) and ...
We all know that chemicals (most commonly Chlorine) are added to the water to protect our health however when bather loads increase, Chlorine by-products are the unfortunate side effect. People are a major source of pollutants (Ammonia from sweat and urine) which react with Chlorine to form chemicals known as Chloramines which are directly responsible for the distinct Chlorine odour as well as eye, nose, throat and lung irritations.. Chloramines can evaporate and are released into the air when water is sprayed or splashed. Staff and swimmers who experience long term exposure may develop allergic sensitivities and will react to even low levels of Chloramines which may force them to avoid the water altogether. Showers prior to swimming are encouraged to help lower the amount of Ammonia entering the water and minimise Chloramine build up risk.. Not only is regular maintenance and water balancing important to avoid health issues, adequate ventilation is also critical in maintaining clean air and a ...
Fluorosilicates have a unique affinity for lead. In fact, lead fluorosilicate is one of the most water-soluble forms of lead. When fluorosilicates in water pass through lead-containing pipes and metal fixtures, the fluorosilicates extract high levels of soluble lead from leaded-brass metal parts. Researchers have found that the mixture of the two chemicals: disinfectant (whether chlorine or chloramine) with fluorosilicic acid has a drastically increased potency, leaching amazingly high quantities of lead. This lead goes into our drinking water and right on into our bodies, where they wreak havoc by poisoning our heart, kidneys and blood, causing irreversible neurological damage and impairing reproductive function ...

The stabilities and speciation of the halamines in water are difficult to characterize experimentally. We provide theoretical estimates of aqueous standard free energies of formation for inorganic chloramines, bromamines, and bromochloramines, based on high-accuracy theoretical standard free energies of formation in gas phase combined with quantum chemical estimates of Henrys law constant. Based on comparisons between several theoretical and experimental datasets, we assign an error of 1.1-1.2 log unit for equilibrium constants of several reactions leading to halamines in water. The reactions of ammonia with HOCl or HOBr that lead to dichloramine, trichloramine, and tribromamine are found to be thermodynamically more favorable than was previously believed. The newly reported equilibrium data also allow us to propose rate constant values for some hydrolysis and disproportionation reactions of dichloramine, monobromamine, and bromochloramine. Finally, theoretical results indicate aqueous acid

3405 Extracellular oxidants such as those generated during inflammation or tissue ischemia-reperfusion can induce apoptosis, but the mechanism through which they do this is not well-defined. We investigated the role of specific protein oxidation in oxidant-induced apoptosis. Using redox-proteomics, we found that the actin-binding protein cofilin is a key target of oxidation that mediates induction of apoptosis by taurine chloramine, a physiological oxidant produced by activated neutrophils. In treated cells, cofilin loses its affinity with actin and translocates from the cytosol to the mitochondria. Only oxidized cofilin interacts with the organelles and it induces mitochondrial swelling and cytochrome c release. Cells become resistant to oxidant-induced apoptosis when Cys to Ala cofilin mutants are over-expressed. Moreover, over-expression of wild-type cofilin causes a 2-fold increase in the sensitivity of cells to oxidant-induced apoptosis. Exposure of cofilin to taurine chloramine results in ...
The District uses chloramines to disinfect your drinking water supply and keep it safe. Chloramines are a long-lasting, safe disinfectant that is becoming increasingly popular across the country. Chloramines are toxic for fish. If you are using tap water, you should assure that the fish are properly protected. Local pet shops can advise you on the best measures to neutralize chloraminated water.. ...
Ann Arbors Water Treatment Plant uses ozone as the primary disinfectant and chloramines as a secondary disinfectant. Chloramines or "combined chlorine" is a compound made up of chlorine and ammonia. These disinfectants are used as an alternative to chlorine treatment because they have fewer by-products, and are a longer lasting disinfectant than free chlorine. In addition, chloramines have less taste and odor than chlorine, and ozone is odorless. Ozone disinfection kills pathogens, improves water taste and reduces odors commonly detected in tap water.. ...
Providing safe drinking water for the citizen and visitors to Manassas is our number one priority. Both free chlorine and chloramines are safe and effective. The Virginia Department of Health publishes guidelines on minimum and maximum concentrations for disinfectants in drinking water. The City of Manassas maintains the water it distributes with those guidelines. The water provided by the city is safe for people and animals to drink, for cooking and bathing, watering the garden, and for all other common uses. However, precautions must be taken to remove or neutralize chloramines and free chlorine during the kidney dialysis process, in the preparation of water for fish tanks and ponds, and for businesses requiring highly-processed water. Any procedure optimized for the removal of chloramines will equally remove free chlorine ...
When the tank is positioned, fill it with clean water from a hose or, better, a rain barrel. If using tap water from the hose, let the water sit in the tank for three or four days before planting or adding fish so that the chlorine in the water has time to evaporate. Once you have fish or other wildlife in your pond, youll need to be careful about how you add water to compensate for evaporation. To top off small tanks like my old stock-tank pond, use rainwater or a bucket of tap water that has had time to de-chlorinate. Larger tanks like my new one may be topped off with water right out of the hose if its only an inch or two; the volume of water in a large tank nullifies the impact of the added chlorine, so long as its not too much.. Update 4/20/13: If you live in the City of Austin, chloramine is now added to our drinking water. (If you live elsewhere, check with your water provider to see if your water contains chloramine; many cities use it.) Unlike chlorine, chloramine does not dissipate ...
Its important to note that Ft Worth uses chloramines to disinfect the water supply instead of chlorine. Chloramines are more difficult to get rid of than chlorine. The subject of chloramine removal is a rather lengthy topic by itself--the short story is you can get rid of it by adding campden tablets (1 crushed tablet per 20 gals) or granulated active carbon (GAC) filtration with a low flow rate. I ran tests with campden tablets and it appears to work. In practice I used GAC filtration--an Omnifilter CB3 cartridge to be exact. Its 0.5 microns and has a flow rate of 0.5 gals/minute--so it takes a little bit to fill up the vessels ...
Scully doesnt have the time to find her name among the test subjects whose ova was used in the Valor Victor. If she had time she would have found it: Scully is but one abductee and William is but one of the babies of this project, an organic Supersoldier, as the babies influenced by the chloramine. Scully was relieved to deliver a healthy baby, but the joy didnt last long: the mobile above William started turning in creepy paranormal fashion! One thing that is different with William, however, is that no chloramine intervened in his otherwise natural conception (8X21: Existence). As well learn later (9X17: William), chloramine did influence him but was not responsible for Scullys pregnancy.. In 48 hours, Mulder had the time to become a father, to guest star in an episode of "The Lone Gunmen", and to take one of the most difficult decisions of his life: to leave Scully and William. Scully explains that "he cant be brought back into this, he cant be brought back to the FBI, its just too ...
Hypochlorite and superoxide radicals can act synergistically to induce fragmentation of hyaluronan and chondroitin sulphates
Activated phagocytes release the haem enzyme MPO (myeloperoxidase) and also generate superoxide radicals (O2*-), and hence H2O2, via an oxidative burst. Reaction of MPO with H2O2 in the presence of chloride ions generates HOCl (the physiological mixture of hypochlorous acid and its anion present at pH 7.4). Exposure of glycosaminoglycans to a MPO-H2O2-Cl- system or reagent HOCl generates long-lived chloramides [R-NCl-C(O)-R] derived from the glycosamine N-acetyl functions. Decomposition of these species by transition metal ions gives polymer-derived amidyl (nitrogen-centred) radicals [R-N*-C(O)-R], polymer-derived carbon-centred radicals and site-specific strand scission. In the present study, we have shown that exposure of glycosaminoglycan chloramides to O2*- also promotes chloramide decomposition and glycosaminoglycan fragmentation. These processes are inhibited by superoxide dismutase, metal ion chelators and the metal ion-binding protein BSA, consistent with chloramide decomposition and ...
Editor:. Re: City claims parkade editorial misleading, Aug. 2.. Who exactly is misleading?. This City of White Rock calling the PAN parkade editorial misleading is a bit like a pot calling the kettle black.. Lately, White Rock seems to have perfected its misleading efforts, especially when it comes to the water issue.. I happen to read the latest "My City My Water" insert that came with the water bill. Rather than provide an honest assessment of the situation in which the city finds itself, it seemed like it was written to convey half-truths and misdirect White Rock water users. There is lots in the pamphlet to convince me monochloramine is so good for me and even tells me that "1 in 5 Americans" drink chloraminated water. Really? Good for them! What it fails to mention is that chloramine use is known to cause pipes to corrode, allowing lead to leach from the older pipes into the water supply. It also misleads by saying that one of the reasons why White Rock does not connect to Metro Vancouver ...
The filtered water goes through one last step, secondary disinfection, to provide continuous disinfection when it is delivered to water users. Our treatment plants use chlorine and chloramine to kill any bacteria or viruses that may be present in the pipes from our plant to your tap. Chloramine is a combined chlorine and ammonia compound used to disinfect potable water. Chlorine was first successfully used as a disinfectant for water in 1908. Chlorine disinfection has just about wiped out water-borne diseases such as cholera and typhoid in the United States. The science of water treatment has progressed so far that detection and control of contaminants in water have reduced health hazards to nearly zero ...

A mechanism for the oxidation of ammonia by hypochlorous acid to form nitrogen gas has been developed at the B3LYP/6-31G(d,p) level of theory using the Gaussian 03 software package. The formation of NH2Cl, NHCl 2, and NCl3 was studied in the gas phase, with explicit water molecules included to examine the transition state energy in aqueous solution. The inclusion of explicit water molecules in the transition state dramatically reduced the reaction barrier in reactions involving transfer of a hydrogen atom between molecules, effects that were not taken into account through use of a solvation model alone. Three mechanisms were identified for the decomposition of chloramine species to form N2, involving the combination of two chloramine species to form hydrazine, dichlorohydrazine and tetrachlorohydrazine intermediates. The highest barrier in each pathway was found to be the formation of the hydrazine derivative.. ...
Chlorine & Chloramine water removal Jacksonville, St.Augustine, Saint Johns, Ponte Vedra, Ponte Vedra Beach FL
Darlene and I closed on our new home a couple of months ago in the Saint Augustine area. We love the community and we love our new home but the water; not so much!! We spoke to several water treatment companies and listened to the different pitches before meeting with Culligans john Lussier. We could tell right away that we were not dealing with a sales person but a highly trained expert in his field. He didnt offer us "free" soap or gift cards. He simply tested the specifics of our water, answered our questions with authority and confidently went about offering options to solve the problems we faced. In the end we chose Culligan and feel we made a very good decision. The water is amazing! It tastes great and leaves your skin feeling silky smooth, clean and refreshed! I highly recommend John Lussier and the Culligan team. ...
Date: Tue, 28 Jun 2005 08:41:13 -0700 (PDT) From: Matt ,baumssl27 at yahoo.com, Subject: Harshness / candi sugar Thanks to everyone who responded to my very vague plea for help with harshness. There were too many suggestions to list here, but one tidbit from the past that may be worth repeating is that its incredibly cheap and easy to eliminate problems associated with chlorine or chloramine in your water supply. Posts in the archives by A.J. deLange state that a small addition of campden (K metabisulfite) will remove chlorine AND chloramine. More precise numbers are available--but his rule of thumb is one 686 mg tablet per 20 gallons. My plan for the future is to start treating in this fashion, stop using bleach to clean/sanitize, replace my possibly chemical-infused hoses, and hope things inprove. If chlorine is the problem, should I expect my latest effort (a hefeweizen brewed using the same process that gave me problems before) to have less of a problem, because it is 70% wheat (i.e. less ...
ATTN: hydrologists, chemists I am able to evaporate 75% of the Chloramine in my SF tap water by pouring into drinking glasses a day or too before I consume. Try it yourself for one month. Then try straight out of the tap... the CHLORINE will ASSAULT YOU! I do not drink the bottom 10%, in the hopes some of the Fluoride will have settled lower in the glass. Q: is Fluoride heavier than water? Q: is HydroFluorosilic Acid heavier than water? this is what most municipalities use. It is a byproduct of SmokeStack scrubbers at Coal Plants in CHINA and hence contains Lead, Arsenic, Mercury, other heavy metals etc. thanks Chloramine compound breaks down into constituents Chlorine and Amonia in transit and turbulence in water pipes.

TheDestruction of Cyanobacterial Peptide Toxins by Oxidants Used in WaterTreatment. ReportNo WSAA 110. May 1996. SYNOPSIS. Initialstudies carried out by the Australian Water Quality Centre into the effect ofwater treatment on the removal of cyanobacterial peptide toxins showed thatsome oxidants were effective in destroying peptide toxins. It was demonstratedthat chlorine, permanganate and ozone rapidly oxidised the toxins undercontrolled conditions whereas monochloramine, hydrogen peroxide and peroxide/UVhad very little, if any effect in reducing toxin concentrations. It was alsofound that the reactions of chlorine with the peptide toxins was pH dependant.. Thisproject extended upon the work already covered to give a more detailed andcomplete study of oxidants which included chlorine, monochloramine,permanganate, ozone, peroxone, and hydrogen peroxide. Their effects on livematerial in particular were investigated along with the effect of pH on thereaction of the oxidants with the peptide toxins. ...

This study shows the ability of physiologically and environmentally relevant doses of nitrite and nitrate to mimic the effects of estradiol in human breast cancer cells. The ability of low doses of nitrite and nitrate to mimic estradiol suggests that the anions may play a role in the etiology and progression of breast cancer due, in part, to their ability to activate ERα. Human exposure to these anions occurs through both exogenous and endogenous sources as a result of the environment, diet, and medicinal drugs and as the breakdown product of nitric oxide. In surface and drinking water, nitrate is generally low but has increased over the last few decades ( 27) due to the use of nitrogen-based fertilizers, contamination from refuse dumps, oxidation of ammonia from human and animal waste, and treatment of drinking water with chloramines ( 28). High amounts of nitrate are also present in some fruits and vegetables as a result of cultivation in greenhouses and in cured and processed meats due to ...

The water may taste funny: GBRA Port Lavaca plant set to switch to full chlorine treatment - Victoria Advocate - Victoria, TX
The Guadalupe-Blanco River Authority will temporarily substitute chlorine as the disinfecting agent in the drinking water treatment process in place of its regularly used chlorine/ammonia compound, known as chloramines, at the GBRA Port Lavaca Water Treatment Plant.. This action will begin on Monday and will last 21 days, after which the plant will resume the use of chloramines, Herb Wittliff, manager for Port Lavaca operations, stated in a news release.. Chlorine and chloramines are used as disinfecting agents for drinking water to safeguard finished water against bacteria that cause water-borne illnesses, Wittliff said. The Texas Commission on Environmental Quality recommends periodically substituting chlorine alone to provide more stability to the disinfecting process and remove any excess ammonia that might have accumulated in distribution systems over time.. As part of the process, the three wholesale customers of GBRA - the City of Port Lavaca, the Calhoun County Rural Water System of GBRA ...

Because of its low degree of cytotoxicity, chloramine-T has been used in direct contact with tissues, including treatment for burns, in whirlpools for wounds, and as an oral mouthwash. In the agricultural industry, it is used as a broad-spectrum biocide for foot-and-mouth disease, swine vesicular disease, and poultry diseases. Chloramine-T was nominated by a private individual for toxicology studies based on its current status as an Investigational New Animal Drug for controlling proliferative gill disease and bacterial gill disease in aquaculture and the need for additional toxicology studies to support its safe use. p-Toluenesulfonamide was studied for toxicity by the NTP because it has been shown to be the major ...

Abstract. Chloramine-T is a disinfectant being developed as a treatment for bacterial gill disease in cultured fish. As part of the drug approval process, a method is required for the confirmation of chloramine-T residues in edible fish tissue. The marker residue that will be used to determine the depletion of chloramine-T residues from the edible tissue of treated fish is para-toluenesulfonamide (p-TSA), a metabolite of chloramine-T. The development and validation of a procedure for the confirmation of p-TSA ...
Infrastructure Quarterly - Many water providers employ systems that utilize chloramines to limit the concentration of disinfection byproducts in their distribution systems. An unintended consequence of chloramines is nitrifications in the systems, resulting in red water at customers taps. The Water Research Foundation (WRF) recently selected Garvers Water Technology Team to research and develop an early detection of nitrification and assist water systems in economically minimizing negative impacts of nitrification by reducing the quantity of water wasted for distribution system flushing. Dr. Ashley Pifer will lead this research funded jointly by Dallas Water Utilities, the City of Houston, and WRF. She will work with researchers from the University of Arkansas for conducting initial laboratory experiments and will also lead field-scale evaluations at Dallas and Houston water distribution systems. Research will begin this summer and will develop new nitrification sensor packages based on fluorescence

Our senses dull as we age; we dont see as well, hear as well, or smell or taste as well. Insights from aging in the worm Caenorhabditis elegans connect oxidative damage of potassium channels to this process. The potassium channel KVS-1 is present in the worms nervous system and in the ASE neurons that mediate the chemotactic response to food substances. Cai and Sesti found that, in a reconstituted system, KVS-1s electrophysiological properties were altered by oxidation (application of chloramine T or hydrogen peroxide). Oxidation increased KVS-1 conductance, which would decrease the excitability of the neuron, a change that was due to Cys113, because a C113S mutant channel was resistant to oxidation-mediated changes in electrophysiological properties. By expressing either the wild-type KVS-1 channel or the C113S-KVS-1 channel in kvs-1-knockout worms, the authors showed that the loss of chemotactic response due to exposure to oxidants was much more pronounced in the worms expressing wild-type ...

Goldsboros public utilities director says a decision to stop putting fluoride in city water is a temporary measure pending testing by state authorities. The injection of fluoride into the citys water was halted June 30, said Karen Brashear, who cited a recent study released by a doctor at the University of North Carolina-Asheville that prompted the decision. The study indicated potential problems for lead contamination when fluoridated water interacted with chloramines. Ms. Brashear emphasized that no evidence of a problem has been found in the citys water system but that city officials wanted to take the precautionary measure until more information can be obtained. "Even though we havent seen evidence, were in compliance with all lead sampling that we have done, just to be on the safe side we have discontinued the fluoride feed pending oversight by other scientists," she said. "We thought we would be more conservative and discontinue use until were more informed." Mrs. Brashear said she ...

When bleach is mixed with acids (typically found in toilet bowl cleaners), it reacts with them to form chlorine gas. When it is mixed with ammonia, it can create chloramine gas, another toxic substance.. In the environment, sodium hypochlorite is acutely toxic to fish. The chlorine in bleach can also bind with organic material in the marine environment to form organochlorines, toxic compounds that can persist in the environment. There may be some circumstances where bleach use is necessary for disease control, but there is little need for it on a regular basis. Tests have shown that washing counters and other surfaces with soap and water removes most bacteria and there are a number of oxygen-based alternatives for laundry uses of bleach.. Phosphates ...

Definition of hypochlorous acid - a weak acid with oxidizing properties formed when chlorine dissolves in cold water and used in bleaching and water treatment.
"Evidence That Monochloramine Disinfectant Could Lead to Elevated Pb Le" by Jay A. Switzer, Vishnu V. Rajasekharan et al.
Many water districts have recently shifted from free chlorine (in the form of HOCl/OCl-) to monochloramine (NH2Cl) as a disinfectant for drinking water to lower the concentration of chlorinated hydrocarbon byproducts in the water. There is concern that the use of NH2Cl disinfectant may lead to higher Pb levels in drinking water. in this study, the electrochemical quartz crystal microbalance is used to compare the effects of these two disinfectants on the dissolution of Pb films. a 0.5 m thick Pb film nearly completely dissolves in a NH2Cl solution, but it is passivated in a HOCl/OCl- solution. X-ray diffraction analysis shows that the NH2Cl oxidizes Pb to Pb(II) species such as Pb3(OH)2(CO3)2, whereas the stronger oxidant, HOCl/OCl-, oxidizes Pb to Pb(IV) as an insoluble PbO2 conversion coating. Although NH2Cl may produce less halogenated organic byproducts than HOCl/OCl- when used as a disinfectant, it may lead to increased Pb levels in drinking water.

July 2000. Background. Until 1999, DWI provided the support services for the voluntary approval system for chemicals used in swimming pool treatment. Following the decision to terminate the voluntary approval system, this study was commissioned in response to unresolved concerns about the conditions of approval for products based on the organobromine compound BCDMH.. Bromine-based disinfectants were introduced during the 1970s and early 1980s for use in recreational pools following the governments recommendation for the discontinuation of the use of chlorine gas. At the time, the perceived benefits of bromine were the improved bactericidal efficiency of bromination over chlorination (due to the greater biological activity of bromamines over chloramines, produced by the combination of the halogen with nitrogenous pollution - ie. urine), and the reduced scale of pH correction required, although it was recognized that elemental bromine is hazardous and capsulated dosing systems were recommended ...

The conductivity requirements of USP water systems approximate the capability of double pass RO systems. On many feed waters, double pass RO will consistently produce the required conductivity. Gas content of the second pass permeate is typically the primary contributor to the on line measured conductivity. In most waters, carbon dioxide is the primary reactive gas that increases the measured conductivity. Carbon dioxide content of the second pass permeate can be reduced by increasing the pH of the feed water to the RO system. This will convert free carbon dioxide gas to bicarbonate ion that can be rejected by membranes. However, in applications where chloramines are present in the feed water, raising the pH will convert ammonium ions to free ammonia gas that will pass through the membranes and will contribute to the measured conductivity of the water. Adjusting the pH to be high for one pass and low for another can address the dual gas problem. Also the use of membrane degasification will ...

DESIGN: The aim of these experiments was to prove increased resistance of common carp (Cyprinus carpio L.) juveniles fed on experimental diets with microalgae biomass supplement (Algadiets) to oxidative stress caused by a disinfectant chloramine-T. In indoor experiments fish were fed on laboratory-prepared extruded diets containing supplement of Chlorella spp. (cf. C. vulgaris Beijerinck) biomass which contains antioxidants (carotenoids) like lutein. The young-of-the-year-old fish were acclimatized and fed on basal diet (control group) and the on diets containing 1, 2, 5 and 10% (w/w) of spray-dried Chlorella biomass (Algadiet 1, 2, 5 and 10) for 14 days followed by 6 weeks. Consequently, fish were treated daily with chloramine-T (Chl-T) at concentration of 10 mg x l(-1) for 1 h in three consecutive days. After this treatment, the indices of oxidative stress and antioxidant enzyme activity were assayed in fish gill, muscle and hepatopancreas ...
Effectiveness of chlorine dioxide in meeting the enhanced surface water treatment and disinfection by-products rules | Journal...
Bench-scale Cryptosporidium inactivation, pilot-scale disinfection by-product (DBP) formation and bench-scale inorganic DBP control experiments were conducted to evaluate the effectiveness of chlorine dioxide in meeting the current and future enhanced surface water treatment and disinfectant/disinfection by-product rules. A new chlorine dioxide generation process in which dilute, humidified chlorine gas is in contact with solid sodium chlorite was employed for this study. Chlorine dioxide was found to be effective in achieving CT values (pH=8 and temperature=20°C) of approximately 50 and 100 mg · min/l for 1-log and 2-log Cryptosporidium inactivation, respectively. Chlorine dioxide did not form significant amounts of trihalomethanes or haloacetic acids. Water spiked with high bromide concentrations resulted in insignificant amounts of organic DBPs after reaction with chlorine dioxide. Reaction of chlorine dioxide with water constituents resulted in the formation of chlorite and chlorate ions. ...
