Decolorization and detoxification of extraction-stage effluent from chlorine bleaching of kraft pulp by Rhizopus oryzae. (1/1030)

Rhizopus oryzae, a zygomycete, was found to decolorize, dechlorinate, and detoxify bleach plant effluent at lower cosubstrate concentrations than the basidiomycetes previously investigated. With glucose at 1 g/liter, this fungus removed 92 to 95% of the color, 50% of the chemical oxygen demand, 72% of the adsorbable organic halide, and 37% of the extractable organic halide in 24 h at temperatures of 25 to 45 degrees C and a pH of 3 to 5. Even without added cosubstrate the fungus removed up to 78% of the color. Monomeric chlorinated aromatic compounds were removed almost completely, and toxicity to zebra fish was eliminated. The fungal mycelium could be immobilized in polyurethane foam and used repeatedly to treat batches of effluent. The residue after treatment was not further improved by exposure to fresh R. oryzae mycelium.  (+info)

Analysis of zinc binding sites in protein crystal structures. (2/1030)

The geometrical properties of zinc binding sites in a dataset of high quality protein crystal structures deposited in the Protein Data Bank have been examined to identify important differences between zinc sites that are directly involved in catalysis and those that play a structural role. Coordination angles in the zinc primary coordination sphere are compared with ideal values for each coordination geometry, and zinc coordination distances are compared with those in small zinc complexes from the Cambridge Structural Database as a guide of expected trends. We find that distances and angles in the primary coordination sphere are in general close to the expected (or ideal) values. Deviations occur primarily for oxygen coordinating atoms and are found to be mainly due to H-bonding of the oxygen coordinating ligand to protein residues, bidentate binding arrangements, and multi-zinc sites. We find that H-bonding of oxygen containing residues (or water) to zinc bound histidines is almost universal in our dataset and defines the elec-His-Zn motif. Analysis of the stereochemistry shows that carboxyl elec-His-Zn motifs are geometrically rigid, while water elec-His-Zn motifs show the most geometrical variation. As catalytic motifs have a higher proportion of carboxyl elec atoms than structural motifs, they provide a more rigid framework for zinc binding. This is understood biologically, as a small distortion in the zinc position in an enzyme can have serious consequences on the enzymatic reaction. We also analyze the sequence pattern of the zinc ligands and residues that provide elecs, and identify conserved hydrophobic residues in the endopeptidases that also appear to contribute to stabilizing the catalytic zinc site. A zinc binding template in protein crystal structures is derived from these observations.  (+info)

Vibrio cholerae O1 El Tor: identification of a gene cluster required for the rugose colony type, exopolysaccharide production, chlorine resistance, and biofilm formation. (3/1030)

The rugose colony variant of Vibrio cholerae O1, biotype El Tor, is shown to produce an exopolysaccharide, EPSETr, that confers chlorine resistance and biofilm-forming capacity. EPSETr production requires a chromosomal locus, vps, that contains sequences homologous to carbohydrate biosynthesis genes of other bacterial species. Mutations within this locus yield chlorine-sensitive, smooth colony variants that are biofilm deficient. The biofilm-forming properties of EPSETr may enable the survival of V. cholerae O1 within environmental aquatic habitats between outbreaks of human disease.  (+info)

Investigation of two evolutionarily unrelated halocarboxylic acid dehalogenase gene families. (4/1030)

Dehalogenases are key enzymes in the metabolism of halo-organic compounds. This paper describes a systematic approach to the isolation and molecular analysis of two families of bacterial alpha-halocarboxylic acid (alphaHA) dehalogenase genes, called group I and group II deh genes. The two families are evolutionarily unrelated and together represent almost all of the alphaHA deh genes described to date. We report the design and evaluation of degenerate PCR primer pairs for the separate amplification and isolation of group I and II deh genes. Amino acid sequences derived from 10 of 11 group I deh partial gene products of new and previously reported bacterial isolates showed conservation of five residues previously identified as essential for activity. The exception, DehD from a Rhizobium sp., had only two of these five residues. Group II deh gene sequences were amplified from 54 newly isolated strains, and seven of these sequences were cloned and fully characterized. Group II dehalogenases were stereoselective, dechlorinating L- but not D-2-chloropropionic acid, and derived amino acid sequences for all of the genes except dehII degrees P11 showed conservation of previously identified essential residues. Molecular analysis of the two deh families highlighted four subdivisions in each, which were supported by high bootstrap values in phylogenetic trees and by enzyme structure-function considerations. Group I deh genes included two putative cryptic or silent genes, dehI degrees PP3 and dehI degrees 17a, produced by different organisms. Group II deh genes included two cryptic genes and an active gene, dehIIPP3, that can be switched off and on. All alphaHA-degrading bacteria so far described were Proteobacteria, a result that may be explained by limitations either in the host range for deh genes or in isolation methods.  (+info)

Chlorine inactivation of Escherichia coli O157:H7. (5/1030)

We analyzed isolates of Escherichia coli O157:H7 (which has recently caused waterborne outbreaks) and wild-type E. coli to determine their sensitivity to chlorination. Both pathogenic and nonpathogenic strains were significantly reduced within 1 minute of exposure to free chlorine. Results indicate that chlorine levels typically maintained in water systems are sufficient to inactivate these organisms.  (+info)

Longitudinal distribution of chlorine absorption in human airways: comparison of nasal and oral quiet breathing. (6/1030)

The fraction of an inspired chlorine (Cl2) bolus absorbed during a single breath (Lambda) was measured as a function of bolus penetration (VP) into the respiratory system of five male and five female nonsmokers during both nasal and oral breathing at a quiet respiratory flow of 250 ml/s. The correspondence between VP and specific anatomic landmarks was found for each subject by a combination of acoustic reflection and nitrogen washout measurements. For both nasal and oral breathing, Lambda reached approximately 0. 95 at the distal end of the upper airways and reached 1.00 within the lower conducting airways. The values of a regional mass transfer parameter computed from the Lambda-VP data indicated that the resistance to Cl2 diffusion in the airway mucosa was negligible compared with the diffusion resistance in the respired gas. Changing the peak inhaled Cl2 concentration from 0.5 to 3.0 parts/million did not significantly affect the distribution of Cl2 absorption, suggesting that the underlying mass transport and chemical reaction processes were linear with respect to Cl2 concentration.  (+info)

Development and testing of a microbiological assay to detect residual effects of disinfectant on hard surfaces. (7/1030)

We describe a glucuronidase bioassay for detecting residual bactericidal activity from the use of disinfectants on hard surfaces; in this assay we used formaldehyde, ethanol, isopropanol, chlorine, and a commercial preparation containing 2-bromo-2-nitro-1, 3-propanediol. Chlorine and the commercial preparation showed bactericidal activity (53.5% and 98.2%, respectively) for a week after disinfection.  (+info)

2015 by the American Thoracic Society. Autopsy specimens from human victims or experimental animals that die due to acute chlorine gas exposure present features of cardiovascular pathology. We demonstrate acute chlorine inhalation-induced reduction in heart rate and oxygen saturation in rats. Chlorine inhalation elevated chlorine reactants, such as chlorotyrosine and chloramine, in blood plasma. Using heart tissue and primary cardiomyocytes, we demonstrated that acute highconcentration chlorine exposure in vivo (500 ppm for 30 min) caused decreased total ATP content and loss of sarcoendoplasmic reticulum calcium ATPase (SERCA) activity. Loss of SERCA activity was attributed to chlorination of tyrosine residues and oxidation of an important cysteine residue, cysteine-674, in SERCA, as demonstrated by immunoblots and mass spectrometry. Using cardiomyocytes, we found that chlorine-induced cell death and damage to SERCA could be decreased by thiocyanate, an important biological antioxidant, and by ...

The dangers of chlorination were first documented in the 1950s. During the Korean civil war, soldiers who were given chlorine tablets for their canteens developed severe cardiovascular diseases. A lot of soldiers died because of heart disease within the next ten years.. While you can do your best to avoid areas exposed to chlorine, an effective way to neutralize the toxic chemical is with ascorbic acid or vitamin C, since it chemically destroys chlorine. (Related: 7 Reasons why you should start eating more blueberries.). The reverse is also true since chlorine can destroy vitamin C. Since both chemicals cancel each other out, consuming more vitamin C than chlorine is crucial to neutralizing the latter.. One gram (g) of vitamin C can neutralize 100 gallons (gal) of water with one part per million (PPM) of chlorine. Take note that one PPM is standard for U.S. drinking water, but it can legally go up to four PPM chlorine.. While the naked eye cannot see the neutralization effect, as it is ...
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 ...
After the first day or two of seeing the chlorine dissipate nearly completely each day, pouring more in each night, I decided to try putting some of the 1 tablets in the pump rather then having to keep pouring chlorine in repeatedly. At first the three 1 tablets alone didnt seem to keep the chlorine level high enough so I added another three. At that point the chlorine level stayed up above 3PPM, maybe even going higher, I found/find it hard to read the OTO test thing, test strips said it was around 3PPM, but at times the OTO looked like it was at 5PPM. I started thinking I had put too many tablets in and had the chlorine level too high, so I started doing more research... Found this forum , which was indeed a good thing ...

To prevent scale formation, calcium hardness should be checked at least once a week. Further, when Calcium hardness is too low, i.e. the water is too soft, it can create a reaction called pH bounce which in turn, can affect the performance of chlorine. The ideal range of calcium hardness is 150 to 400 mg/L.. After examining the key chemicals for maintaining pool water balance and how they interact, you could conclude that chlorine is central to ensuring a healthy pool. We should now drill down and look closer at managing chlorine levels. Measuring Chlorine Measuring chlorine in a pool is a relatively easy task.

Keep the pee, poop, sweat and dirt out of the water! the CDC urges.. Every swimmer should shower before entering the pool, never urinate or defecate in the pool, never swallow the water and anyone with diarrhea should stay out of the water.. Hourly breaks from the water are also suggested so that children have ample opportunity to use the restroom and so that parents can check diapers on younger kids and change them in a bathroom or diaper-changing area - not by the pool where germs can easily spread.. Finally, you can check the free chlorine level and pH before you get in the pool to make sure an error hasnt occurred. Pool testing strips can be purchased at most hardware stores, superstores and pool supply stores.. The proper free chlorine level of pools is 1-3 mg/L or parts per million (ppm), and the pH should be between 7.2-7.8 to maximize the chlorines ability to wipe out germs.. In hot tubs, the free chlorine level should be at 2-4 ppm, or if using bromine to disinfect instead, the free ...

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. ...
Sodium hypochlorite is the main ingredient in household bleach as well as in some of the pool sanitizers you use. Sodium hypochlorite Sodium hypochlorite is chlorine gas dissolved in sodium hydroxide. Sodium hypochlorite disintegrates when heated or if it contacts acids, sunlight, certain metals, and poisonous and corrosive gases, including chlorine gas. Calcium hypochlorite is another low-cost chlorine solution, but it comes with the same issues that liquid chlorine has with a pH of 12, requiring additional treatment. A gallon of sodium hypochlorite (containing 2.34 pounds of solids) will add 12 ppm of FAC (Free Available Chlorine) to 10,000 gallons of water and will increase the TDS by 28 ppm. 1.Sodium hypochlorite , commonly called liquid bleach, is commercially available in strengths approximately 15% by weight. Sodium hypochlorite (NaOCl) is a solution made from reacting chlorine with a sodium hydroxide solution. Sodium hypochlorite, commonly referred to as Active chlorine released from ...

We examined the effects of chlorine on oocyst viability, under the conditions of controlled pH and elevated calcium concentrations required for most community swimming pools. We found that fecal material may alter the Ct values (chlorine concentration in mg/L, multiplied by time in minutes) needed to disinfect swimming pools or other recreational water for Cryptosporidium parvum.
Source. Its very clear the rocket in the video is a match for the Iranian examples, with similar colouring and markings. A very interesting detail is the date of manufacture (2016), which can be clearly seen in this screenshot taken from the media office of Al-Marj video.. The design of the munition is close to that of improvised rocket assisted munitions (IRAMs) used by the Syrian military and documented since 2013, which also use 107mm rocket motors. A typical IRAM takes a conventional rocket and replaces the warhead with a much larger one, increasing the destructive power of the munitions while sacrificing range and accuracy. Whats significant about the IRAMs used in the above attack is instead of an explosive warhead, the warhead was reportedly filled with chlorine gas, the first document instance of this in the conflict. While there have been previous claims of chlorine rockets being used in Syria, this is the first time there has been visual evidence. Previous examples of chlorine gas ...
So you expect to do a lot of swimming this summer. You must know that a day of dipping into a chlorine pool can do some damage to your hair. Chlorine protects swimmers from harmful bacteria that can grow in swimming pools. However, if you soak too long in the water, it can take its toll on your skin and hair. Experts say you have to prepare your hair to save yourself from being sorry that you have ruined your locks. Here are some helpful tips.. Know your hair type. Some hair types are more prone to extreme dryness and tangling. Chlorine in water strips hair of their natural oils, leaving your hair dry and brittle. The curlier and tighter your hair pattern, the more dry and tangled it becomes due to chlorine. Thats because curls are naturally drier than straight or wavy hair.. Be ready before you jump in. Prepare your hair by putting on a rich conditioner or a leave-on conditioner and detangling your hair strands as hair absorbs chlorine. Also, chlorine can turn blonde hair into a greenish ...
0008] Although it would be desirable to be able to vaporize the liquid chlorine stream containing a high concentration of nitrogen trichloride from the chlorine scrubber to avoid the use of a decomposer and organic solvents or the use of other chemicals that generate waste streams that must be handled, the chlorine vaporizers currently used in industry have shortcomings in vaporizing such streams. Industrial chlorine vaporizers are generally non-horizontal units, such as vertical bayonet style units, or horizontal vaporizer units, such as kettle reboiler style units. For convenience in the following discussion, non-horizontal units with a positive slope are referred to as vertical units, meaning units with an angle from the horizontal from 0.1 to 90 degrees. These horizontal and vertical chlorine vaporizers can be of two types, namely: pool boiling vaporizers and plug-flow vaporizers. In a pool boiling vaporizer, such as a vertical bayonet or kettle reboiler style vaporizer, liquid chlorine is ...

Introduction. Aims: Deduce the concentration of a saturated solution of chlorine In order to determine the concentration of aqueous chlorine one must firstly reduce the chlorine to its ions, using a reducing agent, in this case Fe(II). I will be using FeCl2 powder for a source of Fe2+. 2FeCl2 (2) + Cl2(aq) --, 2FeCl3 (aq) [ EQUATION 1] 2Fe2+ (aq) + Cl2 (aq) --, 2Fe3+ (aq) + 2Cl-(aq) 2 : 1 ratio Now if one can calculate the amount of reducing agent left over, it will be possible to calculate the initial Cl2 solution concentration. It is possible to do this by titration of the Fe2+ with Potassium Manganate. [ EQUATION 2] MnO4- (aq) + 5Fe2+(aq) +8H+(aq) --, Mn2+ (aq) + 5Fe3+(aq) + 4H2O(l) 1 : 5 ratio Acidic conditions are necessary, because in neutral or alkaline conditions Potassium Manganate is reduced no farther than Mn+4 and a source of H+ is also needed. Sulphuric acid is a good source of H+, and the SO4-2 ions are not reactive. Hydrochloric acid would react with the KMnO4, and chlorine gas ...
The kinetics, products, and reaction pathways of triclosan/free chlorine reactions were investigated for the pH range 3.5-11. Although pH dependent speciation occurs in both triclosan and free chlorine, only the reaction between HOCl and the phenolate-triclosan was found to play a significant role in the kinetics. The second order rate constant for the reaction between phenolate-triclosan and HOCl was found to be 5.40 (±1.82) à 103 M-1s-1. Three chlorinated triclosan intermediates were tentatively identified based on mass spectral analysis. Additionally, 2,4-dichlorophenol, 2,4,6-trichlorophenol, and chloroform formed under excess free chlorine conditions. The majority of the chloroform formed during the reactions does not form via 2,4-dichlorophenol and 2,4,6-trichlorophenol oxidation. Therefore, the majority of chloroform is likely formed via the oxidation of triclosanâ s phenolic ring. Based on the identified products, a reaction pathway was proposed for the oxidation of triclosan in the ...

Hello Hveragerthi, In the presence of UV light, chlorine dioxide breaks down to chlorine and oxygen. This does not take place in closed loop systems. The reason THM s are formed in the cooling systems of power plants is that the water is cooled in cooling towers that expose the chlorine dioxide in the water to UV light. This breaks down the chlorine dioxide to chlorine and oxygen, and the chlorine reaction forms THM s. It is significant that the EPA limit for THM concentration is 80 PPB. You will notice that chlorine, at 1 PPM produces around 65 PPB, whereas chlorine dioxide, a ...
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.. ​ ...
Chlorine dioxide and chlorite are characterized together for toxicity to reproduction because studies conducted with chlorite, the predominant degradation product of chlorine dioxide, are likely relevant to characterizing the toxicity of chlorine dioxide. In addition, studies conducted with chlorine dioxide may be relevant to characterizing the toxicity of chlorite. Chlorine dioxide is fairly unstable and rapidly dissociates, predominantly into chlorite and chloride, and to a lesser extent, chlorate. There is a ready interconversion among these species in water (before administration to animals) and in the gut (after ingestion). Therefore, what exists in water or the stomach is a mixture of these chemical species (i.e., chlorine dioxide, chlorite, chlorate) and possibly their reaction products with the gastrointestinal contents. Key study: Experimental results: The test procedure was: EPA OPP 83-3 (Prenatal Developmental Toxicity Study). Oral administration of sodium chlorite during ...

The ability of acidic electrolyzed oxidizing water (AEO) and neutral electrolyzed oxidizing water (NEO) to inactivate the murine norovirus (MNV-1) surrogate for human norovirus and hepatitis A virus (HAV) in suspension and on stainless steel coupons in the presence of organic matter was investigated. Viruses containing tryptone (0.0, 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0) were mixed with AEO and NEO for 1 min. In addition, stainless steel coupons containing MNV-1 with or without organic matter were treated with AEO or NEO for 3, 5, and 10 min. AEO was proven effective and generally killed more MNV-1 and HAV in suspension than NEO. Depending on the EO water generator, free chlorine concentrations are required to inactivate MNV-1 and HAV by 3-log PFU/mL or greater ranged from 30 mg/L to 40 mg/L after a 1 min contact time. The virucidal effect increased with increasing free chlorine concentration and decreased with increasing tryptone concentration in suspension. Both AEO and NEO at 70100 mg/L of free ...
TY - JOUR. T1 - Deformation of chlorin rings in the photosystem II crystal structure. AU - Saito, Keisuke. AU - Umena, Yasufumi. AU - Kawakami, Keisuke. AU - Shen, Jian Ren. AU - Kamiya, Nobuo. AU - Ishikita, Hiroshi. PY - 2012/5/29. Y1 - 2012/5/29. N2 - The crystal structure of Photosystem II (PSII) analyzed at a resolution of 1.9 Å revealed deformations of chlorin rings in the chlorophylls for the first time. We investigated the degrees of chlorin ring deformation and factors that contributed to them in the PSII crystal structure, using a normal-coordinate structural decomposition procedure. The out-of-plane distortion of the PD1 chlorin ring can be described predominantly by a large doming mode arising from the axial ligand, D1-His198, as well as the chlorophyll side chains and PSII protein environment. In contrast, the deformation of PD2 was caused by a saddling mode arising from the D2-Trp191 ring and the doming mode arising from D2-His197. Large ruffling modes, which were reported to ...

It should be noted that chlorine dioxide to ingest is a completely new antiviral approach as it is an oxidant and can eliminate by combustion any subspecies or mutant variant of virus. Given the emergency situation in which we currently find ourselves with Covid-19, the oral use of ClO2 is proposed immediately through a protocol already known and used.. 2. Toxicity: The biggest problems that arise with medications in general are due to their toxicity and side effects. New studies demonstrate its viability. Although the toxicity of chlorine dioxide in case of massive inhalation is known, there is no clinically proven death even at high doses by oral ingestion. The lethal dose (LD50, acute toxicity ratio) is considered to be 292 mg per kilogram for 14 days, where its equivalent in a 50 kg adult would be 15,000 mg administered for two weeks of a gas dissolved in water (something almost impossible). The oral sub-toxic doses used are around 50 mg dissolved in 100 ml of water 10 times a day, which is ...
Chlorine dioxide eliminates harmful microorganisms through a process called oxidation. All microorganisms are made up organic molecules such as proteins, polysaccharides and nucleic acids. Oxidation can denature proteins and other organic molecules in the walls and inside microorganisms. When their protective walls are disrupted and their metabolic machinery jeopardized, deadly microorganisms die. Chlorine dioxide is a powerful oxidizing agent. The term microorganism is a broad one. It includes bacteria, viruses and fungi. Even the walls of tough bacterial spores are organic in nature, and thus susceptible to the action of chlorine dioxide. Microorganisms do not have the inherent ability to counter chlorine dioxides oxidative attack. This leads us to the good news: microorganisms cannot develop resistance to chlorine dioxide. Since microorganisms are what create odors, chlorine dioxide effectively and permanently eliminates the odor at its source.. ...

Chlorine levels in swimming pools should fall between 1 ppm and 2 ppm. When potentially hazardous contaminants enter the pool water, the water will need more chlorine than usual for disinfecting the water. Chlorine levels as high as 20 ppm are necessary for thorough decontamination. These situations can include diarrheal contamination and cryptosporidium contamination. Swimmers should not use pools that have chlorine levels in excess of 5 ppm.. ...
In general, full brightness cannot be achieved in one bleaching stage, instead several consecutive stages must be used. Traditionally, bleaching has been done with chlorine-containing chemicals: with (elemental or gaseous) chlorine (C), hypochlorite (H) or with chlorine dioxide (D). Between stages, the dissolved lignin has been extracted with alkali. Typical traditional bleaching sequences were CEHDED and CEDED.. The principle was that the vast majority of the residual lignin was removed with the cheapest chemical i.e. chlorine, and only the final vestiges of lignin were removed with expensive chlorine dioxide.. When the transition was made to recycle bleach plant filtrates in order to reduce bleach plant wastewater effluent, the temperature of the chlorine stage began to rise, which had a detrimental effect on pulp strength. To prevent this, chlorine dioxide was added to the chlorine stage, i.e. the sequence used became (DC)EDED.. The pressurized reactor (EO) or pre-reactor (EO) have made it ...

The aim of this study was to determine the combined effects of slightly acidic electrolyzed water SAEW (pH range 5.06.5, oxidationreduction potential 6501000 mV, available chlorine concentration 1080 mg/L) containing 0, 15, and 30 ppm chlorine and 0, 50, and 100 min of ultrasound US (37 kHz, 380 W) using the central composite design (CCD) on the reductions of Escherichia coli and Vibrio parahaemolyticus (initial value, approximately 67 log10 colony forming unit (CFU) of E. coli or V. parahaemolyticus/g) and the sensory properties on freshly sliced shad (Konosirus punctatus), in comparison with SAEW or US alone. Another aim was to develop the response surface model for E. coli and V. parahaemolyticus in the shad treated with the combination of SAEW and US. Single treatments with SAEW (chlorine 15 ppm), SAEW (chlorine 30 ppm), or US for 50 min caused a much-less-than-1-log10 reduction in the number of both E. coli and V. parahaemolyticus in the shad. In contrast, the combination of SAEW (15 or 30 ...
This study describes the use of alkaline fusion by sodium peroxide to dissolve chlorine and bromine in rocks to produce a solution which, with appropriate pre-treatment, is suitable for analysis by ion chromatography. Results are given for a selection of sedimentary and igneous rocks. The accuracy of the fusion method is evaluated by analysis of Geological Survey of Japan reference materials. Additionally, a spike recovery rest is performed to show that the fusion process is quantitative for chlorine and bromine. The results for chlorine are in the range 58-3860 mg kg(-1) and show good agreement both with results obtained by pyrohydrolysis with flow injection colorimetric detection and results obtained by aqueous leaching of the samples with ion chromatography detection. Results for bromine are in the range ,3-4.5 mg kg(-1). Because of the relatively few data obtained in this study and the relative paucity of published data for reference materials, an assessment of the accuracy of the fusion ...
Bacterial growth in potable water distribution systems was studied in a pilot reactor system designed to model the plug flow characteristics in a water main. Experiments were performed to measure specific cellular growth rates and numbers of cells growing on the pipe walls (biofilm cells) and cells suspended in the water phase (planktonic cells) to determine the relative contribution of biofilm accumulation to the bacterial populations in distribution mains. The experiments were performed with chlorine-free water at a water treatment plant as well as with disinfectant (chlorine) added to the reactor influent to examine the effect of chlorine on biofilm accumulation and planktonic cell numbers. The results indicate that biofilm growth and detachment accounted for most, if not all, the planktonic cells present in the bulk water of a chlorine free system. Chlorine affects the accumulation and spatial distribution of the biofilm ...
Equations (9) to (18) can be used (with the aid of a simple, iterative computer program) to solve for (DGH), (DGC), (DGCl) and (DGBr). However, it is clear that equations (9) to (11) can be replaced by a general equation for the chlorine substituted methanes, likewise equations (12) to (14) can be replaced by a general equation for the bromine substituted methanes and equations (15) to (17) can be replaced by a general equation for the chlorine substituted bromomethanes. Similarly, equations (15) and (18) are members of the bromine substituted monochloromethanes.. Thus, the general equation for the chlorine substituted methanes will be,. ...

It now is widely recognised that the global temperature is rising, a phenomenon which could alter the effects of pollution on wildlife. In order to assess the role of temperature and exposure to chlorine due to cooling water discharges, a battery of metabolic, oxidative stress and histological parameters were evaluated in Mytilus galloprovincialis after 15 and 30 days at 15 °C and at two increased temperatures (+5 and + 10 °C). Diverse gill pathologies such as haemolymphatic sinus dilatation, an increased number of mucocytes and granulocytes as well as a lower number of cilia were observed after 30 days exposure at higher temperatures. Protein, amino acid, triglyceride and fatty acid levels decreased when the temperature increased, as a consequence of higher energetic demand. Similarly, acetylcholinesterase, catalase and glutathione S-transferase activities showed an inhibition at higher temperatures, although gill lipid peroxidation levels remained unaffected. Our results suggest that ...
Syrian regime armed forces on Monday targeted rebel-held Jobar neighborhood of Damascus by chlorine gas, but no suffocation cases have been reported, activists said.. Local activists have documented more than 20 toxic gas attacks in the last three months as Bashar al-Assad forces carry out the fiercest assault on Jobar since the start of Syrian revolution in 2011, conducting hundreds of airstrikes.. Meanwhile, rebels have thwarted attacks launched by Assad forces north of the embattled district, killing three troops, sources said.. The regime is trying to retake Jobar after the capture of several rebel-held areas around the center of the capital last summer, including the town of Mleiha just outside Damascus on August 14, according to Reuters.. Jobar was seized by armed rebels over a year ago, and the area has since endured ongoing ground shelling by government missile batteries located in Damascus city center..

So while were on the topic of these normal carrots being mechanically peeled and shaped to look like baby carrots, lets debunk some misinformation that is being spread about the baby carrots and chlorine causing white marks on the carrots. From the viral piece of Facebook spreading about mini carrots and chlorine it states, You will notice that once you keep these carrots in your refrigerator for a few days, a white covering will form on the carrots. This is the chlorine which resurfaces. This part is just absolutely absurd. The white covering is simply cuts and gashes from the carrot being peeled and mechanically shaped into a cute little baby carrots. You can test this out for yourself by getting an unaltered carrot and cutting it up with a knife and letting it sit out. You will notice that the parts youve cut with the knife will look white as the carrot dries out and the water evaporates.. I put two pictures below of the mini peeled carrots I buy from Costco under the brand Earthbound ...
As one of the most widely used domestic fuels, the detection of possible leakages of Liquefied Petroleum (LP) gas from production plants, from cylinders during their storage, transport and usage is of utmost importance. This article discusses a study of the response of undoped and chlorine doped electrodeposited n-type Cuprous Oxide (Cu2O) films to of LP gas. Undoped n-type Cu2O films were fabricated in an electrolyte bath containing a solution of sodium acetate and cupric acetate whereas n-type chlorine doped Cu2O thin films were prepared by adding a 0.02 M cuprous chloride (CuCl2) into an electrolyte solution containing lactic acid, cupric sulfate and sodium hydroxide. The n-type conductivity of the deposited films was determined using spectral response measurements. The structural and morphological properties of the fabricated films were monitored using X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). Due to doping, the overall conductivity of the chlorine doped n-type Cu2O films
This week, member company Solvay continued its exit of Western European chlor-alkali by divesting its chlorine and peroxide derivatives site at Torviscosa to Caffaro Industrie SpA. This follows on from previous activities during the Inovyn (vinyls) joint venture with Ineos (which was completed recently).. Caffaro, a fine chemicals producer will invest in the site, which mostly contains units for chlorine and chlorine derivative production, in order to bring it into line with their existing chemicals portfolio..

In 1998, using Raman and ultraviolet spectroscopic radiation, scientists proved that the bactericidal activity of chlorine treatment was quantitatively linked to the concentration of the hypochlorous acid in the chemical solution. Further, the pH dependence discovered indicates an equilibrium amongst the chlorine, hypochlorous acid, and hypochlorite13. Though typically chlorine activity decreases at higher pH, compromise with other factors (such as prevention of skin and eye irritation) places the ideal pH for swimming pools at approximately 7.2-7.814. DNA microarray can be used to monitor water quality more precisely15. A study in 2011 established 26 different microbial probes, and claimed to drastically reduce the time and labor required with current methods of identifying the presence of microbes in drinking water sources16. The success of shock chlorination, however, is not straightforward or universal. Due to the process of horizontal gene transfer (in which bacteria can pick up DNA from ...
