Carbon disulphide absorption during xanthate reagent mixing in a gold mine concentrator. (1/101)

A xanthate reagent mixer at a gold mine concentrator was exposed to carbon disulphide by extensive skin contamination with xanthate powder and solution during the reagent mixing process. Absorption of carbon disulphide was confirmed by the detection of urinary 2-thiothiazolidine-4-carboxylic acid (TTCA). Drager colorimetric tube testing during subsequent mixing recorded a maximum concentration of at least 60 ppm carbon disulphide. An illness consisting of predominantly gastrointestinal symptoms began 20 h after the exposure. Although this may have been due to carbon disulphide toxicity this is by no means certain. The need for engineering controls, impervious protective clothing and full-face respirators with particulate and organic vapour cartridges is discussed. This episode occurred at another mine site, unrelated to Mount Isa Mines Limited.  (+info)

Preliminary external quality assessment for the biological monitoring of carbon disulfide with urinary 2-thiothiazolidine-4-carboxylic acid. (2/101)

Four laboratories have participated in an external quality control assessment for the determination of 2-thiothiazolidine-4-carboxylic acid (TTCA). TTCA is used as a biomarker for exposure to CS2. Thirteen different urine samples were analyzed by each laboratory. Ten of these were spiked with known amounts of TTCA, and had either a high or intermediate creatinine content. Two samples without any TTCA were used as controls and one sample was a pool of samples of urine from five employees occupationally exposed to CS2. The latter had unknown TTCA content. For each sample, TTCA and creatinine concentration were determined. The samples were supplied in three consecutive deliveries. Several samples were offered more than once. Thus, within-laboratory variability could be established for creatinine and TTCA determination and accuracy could be determined for TTCA analysis. Within-laboratory variability was low for all laboratories for creatinine, although laboratory D seemed to have a slight downward bias. Accuracy for TTCA was good for all laboratories. No significant mean deviation from the expected TTCA value was encountered. There does not seem to be any clear influence of the TTCA concentration level of the samples on the accuracy and within-laboratory variability. Two of the four laboratories (A and C) showed lower within-laboratory variability than the other two for TTCA, although coefficients of variation between replicated samples are high for these two laboratories as well. The laboratory giving the best accuracy, gave the highest within-laboratory variability. A non-systematic, random error is probably the source of this. The results of this preliminary study indicate that analysis of TTCA, although regarded as an established biomarker, can give biases and thus negatively interfere with inferred dose-effect or dose-response relationships in occupational epidemiology.  (+info)

Exposure of C57BL/6 mice to carbon disulfide induces early lesions of atherosclerosis and enhances arterial fatty deposits induced by a high fat diet. (3/101)

Even though atherosclerotic cardiovascular disease (ACVD) is the number one cause of death in the United States, the effects of environmental toxicants on this process are less well studied than the effects of chemicals on the second leading cause of death, cancer. There is considerable epidemiological evidence that workers exposed to carbon disulfide (CS2) have increased rates of ACVD, and there is conflicting evidence of the atherogenic potential of CS2 from animal studies. Chemical modification, such as oxidation of low-density lipoproteins (LDL), is tightly associated with increased LDL uptake by macrophages and the development of arterial fatty streaks. CS2 has been previously demonstrated to modify several proteins in vitro including LDL, and others in vivo through derivatization and covalent cross-linking. To investigate both the capacity of CS2 to induce arterial fatty deposits by itself, and its ability to enhance the rate of fatty deposit formation induced by a western style, high fat diet, groups of 20 female C57BL/6 mice were exposed to 0, 50, 500, or 800 ppm CS2 by inhalation. Half the animals in each group were placed on an atherogenic high fat diet and half on a control diet (NIH-07). Animals were sacrificed after 1, 4, 8, 12, 16, or 20 weeks of exposure, and the rates of fatty deposit formation under the aortic valve leaflets were evaluated. Exposure of mice on the control diet to 500 and 800 ppm CS2 induced a small but significant increase in the rate of fatty deposit formation over non-exposed controls. A more striking result was observed in the animals on the high fat diet. There was marked enhancement of the rate of fatty deposit formation in mice exposed to 500 and 800 ppm over the animals on the high fat diet alone. In addition, there was a small but significant enhancement in mice exposed to 50 ppm over the rate of fatty deposit formation induced by the high fat diet alone. Analysis of erythrocyte spectrin for protein cross-linking revealed a dose-dependent formation of alpha- and beta-heterodimers in animals on both diets. These data demonstrate that CS2 is atherogenic at high concentrations, but more importantly, suggest that, in conjunction with other risk factors, CS2 at relatively low concentrations can enhance atherogenesis.  (+info)

Simultaneous analysis of urinary 2-thiothiazolidine-4-carboxylic acid and thiocarbamide as a biological exposure index for carbon disulfide exposure. (4/101)

The objectives of this study were to develop optimal analytic methods for detecting urinary 2-thiothiazolidine-4-carboxylic acid (TTCA) and thiocarbamide simultaneously and to evaluate the usefulness of these metabolites to a biological exposure index (BEI) for carbon disulfide (CS2) exposure. For this experiment, synthesized TTCA and thiocarbamide were used. The synthesized TTCA was identified by infrared spectrophotometer, nuclear magnetic resonance spectrometer and thin layer chromatography. The recovery rates of both metabolites were calculated to find the optimum analytical method. The amounts of urinary TTCA and thiocarbamide were measured by using an ultraviolet detector connected to high performance liquid chromatography (HPLC) after the administration of CS2 (350, 700 mg/kg) into Sprague-Dawley rats intraperitoneally. The maximum absorbance wave lengths for TTCA and thiocarbamide were 272 and 236 nm, respectively. Ethyl acetate extraction with NaCl as a salting-out reagent was used as a simultaneous extraction method for these metabolites. HPLC conditions for these metabolites included using a NH2 column, 50 mM KH2PO4: acetonitrile (85:15) and pH 3. Excreted amounts of urinary TTCA and thiocarbamide were increased significantly following CS2 administration. TTCA, which was already adopted as a BEI for CS2 by the American Conference of Governmental Industrial Hygienists (ACGIH), seems to be a more useful BEI for CS2 exposure than thiocarbamide. However further studies are needed to increase analytical efficiency before thiocarbamide can be adopted as a BEI and to apply this analytic method for simultaneous analysis of these metabolites in workers exposed to CS2.  (+info)

Toluene-3,4-dithiol analysis of blood for assessing carbon disulfide exposure. (5/101)

Carbon disulfide is a neurotoxic compound used in the production of viscose rayon, and is a major decomposition product of dithiocarbamates used in industry, agriculture, and medicine. Methods used currently for assessing exposure to CS2 are limited in their ability to evaluate cumulative exposures and provide useful information for relatively short periods of time after exposure has ended. The present investigation evaluates a method for monitoring CS2 exposure that consists of cleaving the thiocarbonyl function of free CS2 or certain CS2-generated modifications on proteins using toluene-3,4-dithiol. The resulting toluene trithiocarbonate product is then quantified using reverse-phase high-performance liquid chromatography. The sensitivity, dose response, kinetics and specificity of this biomarker in blood were examined in rats administered CS2 by inhalation, intraperitoneal injection, or gavage for acute through subchronic periods. Dithiol reactive functions in plasma and hemolysate demonstrated a linear dose response over a wide range of exposure levels, were dependent upon the duration of exposure, and appeared to have an appropriate sensitivity for evaluating occupational levels of exposure. Elimination rates of dithiol reactive functions may also be dependent upon exposure duration and exhibit different kinetics for plasma and hemolysate suggesting that elimination rates may be useful for estimating cumulative exposure and intervals between exposure and sample procurement. Dithiol analysis, used in conjunction with previously established erythrocyte protein cross-linking biomarkers, may provide a means to characterize the internal dose of CS2 resulting from acute through chronic periods, and may provide insight into the level of CS2-mediated covalent protein modifications occurring within the nervous system.  (+info)

Indicators of cardiovascular risk among workers exposed to high intermittent levels of carbon disulphide. (6/101)

The effects of exposure to carbon disulphide have been studied mostly among workers in the viscous rayon industry, where the usual exposure profile has been relatively steady exposure over work shifts. We investigated 13 workers in a small chemical company who were exposed to low levels, peaking intermittently to relatively high levels in the range of 100-200 ppm at the end of the work shift, a pattern that may change the risk profile. Our investigation was part of a compliance order that was fought by the company and our access and follow-up was limited. Two workers had burns on their bodies associated with exposure to caustic. Four had elevations in total serum cholesterol, one had elevated serum triglycerides and three had elevations in fasting blood glucose--two of them were known to be diabetics before employment and one had a history of unexplained peripheral neuropathy. No consistent pattern suggestive of a defined lipoprotein abnormality was obvious but several atherogenic profiles were observed. Five had abnormalities on electrocardiogram, four of whom appeared to be among the most heavily exposed. The presence of these changes taken together in this context may suggest accelerated atherosclerotic changes. Tests of liver and kidney function were within the normal range for all workers, as was a complete blood count. Four of the workers had evidence of a bilateral reduction in hearing threshold at 4,000 Hz. A complete set of recommendations was forwarded to the employer, emphasizing further control of exposure to carbon disulphide, personal protection requirements and a cardiovascular risk reduction programme. Conditions improved in the plant following modifications introduced in response to a stop work order from the provincial government's occupational health and safety agency. However, a fire in 1998 put the company out of business and ended further follow-up or interventions. We conclude that these findings, while difficult to interpret because of the circumstances of the investigation, are compatible with an atherogenic effect of exposure to peaking levels of carbon disulphide. The observation should be tested in a larger population with fewer confounding factors and greater control over the investigation.  (+info)

Characterization of carbon disulfide neurotoxicity in C57BL6 mice: behavioral, morphologic, and molecular effects. (7/101)

Female C57BL6 mice were exposed to 0 or 800 ppm carbon disulfide (CS2), 6 h/d, 5 d/wk for 20 weeks. The neurologic function of all mice was assessed once at the end of exposures using a functional observational battery. General health effects included a decrease in body weight gain, piloerection, hunched body posture, and ptosis. Treatment-related effects included altered gait (uncoordinated placement of hind limbs and ataxia) and impaired function on an inverted screen test. In addition, rearing and locomotor movement were decreased in treated mice. Focal to multifocal axonal swelling was seen predominantly in the muscular branch of the posterior tibial nerve, and occasionally giant axonal swelling was detected in the lumbar segment of the spinal cord. Electron microscopic examination revealed swollen axons with massive accumulation of neurofilament proteins within the axoplasm. Covalent cross-linking of erythrocyte spectrin (surrogate protein to neurofilament protein) was demonstrated in mice exposed to CS2 but not in mice receiving filtered air. These data provide supportive evidence that covalent cross-linking of neurofilament proteins is a significant feature of the axonal swellings in mice produced by inhalation exposure to CS2.  (+info)

Behavioral toxicology of carbon disulfide and toluene. (8/101)

Organic solvents are pervasive in the communal and industrial environments. Although many are potent central nervous system agents, clearly delineated behavioral effects have played only a minor role in the formation of exposure standards. A comprehensive behavioral pharmacology and toxicology of these compounds is one aim of US/USSR collaboration. The current report describes some actions of carbon disulfide and toulene. Earlier data about the actions of carbon disulfide on pigeon operant performance indicated disruption of schedule-controlled key-pecking. Primate data are now described from a situation designed to determine aversive thresholds to electrical stimulation. Effective concentrations of carbon disulfide produced both a rise in the amount of electric shock tolerated and a diminution of the response force exerted by the monkeys. In experiments with toluene, pigeons were shown to elevate key-pecking rate in an operant situation at certain concentrations. Toluene also was studied for its capacity to maintain self-administration in the same way as drugs of abuse. Monkeys worked to gain access to toulene vapor just as they work for opiates or amphetamines. The current experiments demonstrate how comprehensive the range of behavioral toxicology needs to be to deal with environmental health issues.  (+info)

Exposure to carbon disulfide can occur by breathing it in the air and by drinking water or eating foods that contain it. Breathing very high levels can be life threatening because of its effects on the nervous system. Breathing low levels for long periods may result in headaches, tiredness, trouble sleeping, and slight changes in the nerves. Carbon disulfide has been found in at least 210 of the 1,430 National Priorities List sites identified by the Environmental Protection Agency (EPA).
We investigated past working exposure to CS2 characteristics from investigable 633 ex-workers identified as CS2 poisoning-related occupational diseases including cumulative CS2 exposure index. Furthermore, we studied the prevalence of their major chronic diseases associated with CS2 poisoning recently after many years. Comparing work environment measurement data reported in the 1991-1992, these values were similar to them. After the subjects were identified as CS2 poisoning-related occupational diseases, there are subjects over 70 years of average age with chronic diseases. Disorders of the nervous system and sensory organs, hypertension, psychoneurotic disorder, cerebrovascular disease, diabetes, coronary artery disease, and arrhythmia are the descending order of the prevalence for their chronic diseases.. In our study, there were several advantages to the survey method. We used an evidence-based approach to estimate past exposure to CS2 and to examine the presence or absence of chronic ...

The results of an experimental investigation of a new geometry for producing phase conjugation by Brillouin-enhanced four-wave mixing are presented. In this geometry, the four-wave mixing medium is carbon disulfide, and the backward-going pump wave is created from the transmitted forward-going pump wave by stimulated Brillouin scattering (SBS) in glycerol. The two pump waves are hence phase conjugates of each other, and the quality of the phase-conjugation process is not degraded even by the use of an aberrated pump wave. The probe wave is created by SBS in carbon disulfide, which has a Brillouin frequency half that of glycerol, and the conjugate wave is therefore generated at the same frequency as the probe. Since the pump and signal waves differ in frequency by the Brillouin frequency of the carbon disulfide four-wave mixing medium, high reflectivities (approximately 2000%) are obtained as a result of Brillouin resonance enhancement.. © 1987 Optical Society of America.

Control of rodent infestations using acute-rodenticide baiting is frequently fraught with difficulties involving bait-shyness and neophobic effects. To simulate some of the parameters encountered in baiting situations, pre-weighed quantities of Environmental Protection Agency (EPA) standard challenge bait mixture were used as a highly palatable bait base to induce feeding without the need for food deprivation in Wistar-strain laboratory albino rats. Individual animals were tested for attractant effects of 3 odors (rat urine, preputial gland extract, and carbon disulfide) and a natural repellent odor (coyote urine) in an observation area constructed of clear plastic panels containing a central alley and 2 choice compartments. Three measures of rat preference - the bait intake levels of challenge bait, arena compartment choice, and time expended in each compartment - suggested that the carbon disulfide at 10 ppm had an attractant effect. None of the other tested odors produced consistent effects on these

The higher the ratio of cellulose to combined sulfur, the lower the solubility of the cellulose xanthate. The xanthate is dissolved in aqueous sodium hydroxide (typically 2-5% w/w) and allowed to depolymerize to a desired extent, indicated by the solutions viscosity. The rate of depolymerization (ripening or maturing) depends on temperature and is affected by the presence of various inorganic and organic additives, such as metal oxides and hydroxides.[3] Air also affects the ripening process since oxygen causes depolymerization.[4] Rayon fiber is produced from the ripened solutions by treatment with a mineral acid, such as sulfuric acid. In this step, the xanthate groups are hydrolyzed to regenerate cellulose and release dithiocarbonic acid that later decomposes to carbon disulfide and water:[5] ...
ABSTRACT. A simple catalyst-free, and highly regioselective approach to 2-hydroxyalkyl dithiocar bamates is described which involves a one-pot reaction of various amines and carbon disulfide,CS2, with epoxides in ethanol at room temperature.. 1. Introduction. The formation of carbon-sulfur bond, especially under a green and safe condition, is an important transformation in organic synthesis. Sulfur containing compounds are found in many products of biological [1-4] and medical [5-7] relevance as well as in commercial drugs [8].. Dithiocarbamates are a class of fungicides extensively used worldwide on a range of crops mainly due to their efficiency in controlling plant fungal diseases and relatively low mammalian acute toxicity [9]. They have also received much attention due to their wide utility as potent anticancer agents [10,11] and cell apoptosis inhibitors [12-14]. Dithiocarbamates have found applications in the rubber industry as vulcanization accelerators [15], in controlled radical ...
Foliage has an OK crown. It gets a bit disorganized at the very end. So if any drones photograph the top of my head maybe Ill deny I knit it. Overall its a beautiful hat and a well-crafted pattern.. Knitting with Sueno set me to wondering about how they manage to get rayon from bamboo. Generally, rayon production of any kind isnt a pretty picture. Its all chemically reshaped cellulose. Bamboo will do as well as wood pulp to produce rayon. And since bamboo grows fast its likely a more ecologically sensitive choice if you want to end up with rayon. But both processes create carbon disulfide as a byproduct. Thats very nasty stuff. Especially if anyone inhales the fumes. Im hoping that the workers who have to cook up this stuff are adequately protected.. This next orange hat is Jennifer Myricks Skywalk. I knit mine in Plymouth Yarns Worsted Merino Superwash.. ...
The cellulosic component of the wood is unaffected by this treatment, but the cementing material called lignin, which is present in the wood, is converted into its sulphonated compound which is soluble in water. This can be washed off, thereby purifying the remaining cellulose. This cellulose is treated with excess of water. After this it is treated with a bleaching agent (sod hypochlorite) and finally converted into paper boards or sheets. This is called wood pulp, which is normally purchased by the manufacturers of viscose rayon ...
Carbon subsulfide is an inorganic chemical compound with the formula C3S2. This deep red liquid is immiscible with water but soluble in organic solvents. It readily polymerizes at room temperature to form a hard black solid. C3S2 was discovered by Béla Lengyel, who assigned it an unsymmetrical structure. Later, infrared and Raman spectroscopy showed that the structure is symmetrical with a D∞h point group symmetry, i.e. S=C=C=C=S. This compound is analogous to carbon suboxide whose structure is O=C=C=C=O. Lengyel first synthesized this compound by passing carbon disulfide (CS2) vapor through an electric arc with carbon electrodes. This treatment produced a black solution that after filtration and evaporation gave a cherry-red liquid. He determined the molecular mass by cryoscopy. Later preparations of C3S2 include thermolysis of a stream of CS2 in a quartz tube heated to 900 to 1100 °C as well as flash vacuum pyrolysis (FVP) of 1,2-dithiole-3-thiones. Among its few known reactions, C3S2 ...
Quinoline, hygroscopic, yellowish oily liquid, is an aromatic nitrogen compound characterized by a double-ring structure contains a benzene and a pyridine. (Pyridine is a ring structure compound of five carbon atoms with a nitrogen atom). These two rings are fused at two adjacent carbon atoms. Quinoline itself is the simplest member of the quinoline. It can be prepared by the distillation of coal tar or by synthesis from aniline. It is soluble in water as well as in alcohol, ether, and carbon disulfide. Isoquinoline differs from quinoline in nitrogen position. Quinoline family compounds are widely used as a parent compound to make drugs (especially anti-malarial medicines), fungicides, biocides, alkaloids, dyes, rubber chemicals and flavoring agents. They have antiseptic, antipyretic, and antiperiodic properties. They are also used as catalyst, corrosion inhibitor, preservative, and as solvent for resins and terpenes. They are used in transition-metal complex catalyst chemistry for uniform ...
This study describes a novel model of cancer. Cancer is caused, according to this model, by two toxic molecules, COF2 (carbonyl fluoride) and CS2 (carbon disulfide). COF2 acts as a catalyst and produces CS2. CS2 acts as a catalyst and produces COF2. Hence, the molecules COF2 and CS2 have the ability to reproduce each other, i.e. to create a chain reaction where COF2 and CS2 are multiplied. COF2 and CS2 are toxic. It is proposed that long-term cell exposure to COF2 and CS2 may disturb cell apoptosis and cause uncontrolled cell growth, i.e. cancer. Consequently, cancer is caused by a disease causing mechanism or agent and not by a pathogen. However, cancer can be initiated by e.g. a bacteria or virus that contains the molecules COF2 and CS2, wherein these molecules start a chain reaction producing COF2 and CS2 in the infected area and where the result can be cancer. The study describes why Fe2O3 (iron (III) oxide) may have a therapeutic effect on cancer.
Link to pdf of Chapter 2 Occupational Medicine: State of the Art Reviews; Chapter 2: Research Findings Linking Workplace Factors to CVD Outcomes Authors: Paul Landsbergis, Kyle Steenland, Lawrence Fine, Karen Belkic, Peter Schnall, Dean Baker, Tores Theorell, Johannes Siegrist, Richard Peter, Robert Karasek, Michael Marmot, Chantal Brisson, Finn Tuchsen Abstract A variety of workplace conditions have been implicated as risk factors for cardiovascular disease (CVD). These include shift work, long work hours, and chemical (e.g., carbon disulfide, nitrate esters, carbon monoxide, methylene chloride, solvents), physical (e.g., cold, heat, noise, passive smoking, sedentary work) and psychosocial conditions. The most consistent evidence is provided by sources of psychosocial stress at work. The evidence strongly suggests a causal association between job strain (a combination of high psychological demands and low job decision latitude, or low job control) and hypertension and CVD. Low decision latitude is also
A modified procedure was developed for the measurement of the effective air exchange rate, which represents the relationship between the pollutants emitted from indoor sources and the residents level of exposure, by placing the dosers of tracer gas at locations that resemble indoor emission sources. To measure the 24-h-average effective air exchange rates in future surveys based on this procedure, a low-cost, easy-to-use perfluorocarbon tracer (PFT) doser with a stable dosing rate was developed by using double glass vials, a needle, a polyethylene-sintered filter, and a diffusion tube. Carbon molecular sieve cartridges and carbon disulfide (CS2) were used for passive sampling and extraction of the tracer gas, respectively. Recovery efficiencies, sampling rates, and lower detection limits for 24-h sampling of hexafluorobenzene, octafluorotoluene, and perfluoroallylbenzene were 40% ± 3%, 72% ± 5%, and 84% ± 6%; 10.5 ± 1.1, 14.4 ± 1.4, and 12.2 ± 0.49 mL min−1; and 0.20, 0.17, and 0.26 μg m-3,

As poor air quality is a major cause of respiratory diseases, regular monitoring of air quality is important. Air quality can be expressed on the basis of the concentration of pollutants such as acetaldehyde, acrylonitrile, aniline, benzene, carbon tetrachloride, chloroform, and chloromethyl methyl ether in the air. VOC monitors are used to measure different levels of VOC gasses in the ...
0005]Accordingly, a device is needed to extract low levels (trace levels) of volatile, semi-volatile, and non-volatile compounds from the oral cavity, including breath and saliva, for the purpose of advancing the field of breath metabolomics. Such a device would also be useful in dental, food and flavor sciences. For example, in dental science, oral health may be assessed by sampling metabolites present in the saliva and breath. Common maladies such as gum health may be diagnosed based on the presence and concentration of known metabolites generated by infection including compounds associated with foul odor such as carbon disulfide, methyl mercaptan, and dimethyl sulfide. In food and flavor sciences, flavor and taste are known as chemosenses, meaning the sense of taste and smell (flavors, tastes and fragrances) are the brains interpretation of signals generated by interactions of chemicals (from foods and fragrances) with receptors in the mouth and nose. By detecting and measuring these ...
Shungite (Sh) are the black Precambrian rocks of Karelia (Russia) where the first natural occurrence of fullerenes was found. Carbon-rich Sh - a natural composite with a submicronic degree of uniformity in distribution carbon and mineral components that allows to consider them as metastable solid solutions. Presence of fullerenes and aluminosilicate components in such Sh supposes a wide spectrum of catalytic transformations of substance. Various types of the substance organization during concentrating of the water - carbon disulfide shungite-extracts are considered. The organization of fullerene-like quasi-crystall particles from icosahedral composite molecules of type a core C60 - shell S42 structure is shown in [1]. At a final stage of such particle origin the stress crack are formed and the recrystallization of substance as a film polycrystal (the upper optical micrograph) by account of high concentration CS2 inside a shell is possible.. The globular organization of aluminosilicate component ...

In this experiment, I recrystallized garden sulfur (90% pure) to make pure sulfur crystals that gleam in the light and are a light yellow color. First, I acquired a solvent for sulfur. Since sulfur dissolves well in toluene, xylene, and carbon disulfide, I picked the most common option--xylene. My xylene came from paint thinner (it listed xylene as an component). To separate the xylene from the methanol and acetone also in the paint thinner, I mixed equal volumes of water and paint thinner and vigorously shook. This should be done outside, as the vapors are unhealthy. I poured the mixture into a graduated cylinder and let it settle for 15 minutes. The xylene, which is insoluble in water, floated at the top, while the acetone and methanol remained in the water layer. I syringed off the xylene and ended up with ~45mL from three 50mL batches of paint thinner ...

Pulp is steeped in a sodium hydroxide solution and converted to alkali cellulose. The addition of carbon disulfide causes cellulose xanthate to form. The xanthate is dissolved in diluted sodium hydroxide solution, filtered, deaerated, ripened and metered through spinnerets into a sulfate regenerating bath. After that, the fibers are stretched, cut, desulfurized and bleached with a sodium hypochlorite solution or a hydrogen peroxide solution. The fibers are repeatedly washed between the individual subsequent treatment steps. After the last wash, finishing agents are applied to ensure the running and gliding properties for further processing. As a final step, the fibers are dried and pressed into bales. Zinc sulfate is removed or recovered from the wastewater (At site in Lenzing only). Sulfur-containing gases generated during spinning are collected and recovered once ...
A compound is a substance composed of two or more elements chemically combined with each other. Historically, the distinction between compounds and mixtures was often unclear. Today, however, the two can be distinguished from each other on the basis of three primary criteria. First, compounds have constant and definite compositions, while mixtures may exist in virtually any proportion. A sample of water always consists of 88.9% oxygen and 11.1% hydrogen by weight. However, a mixture of hydrogen and oxygen gases can have any composition whatsoever.. Second, the elements that make up a compound lose their characteristic elemental properties when they become part of the compound, while the elements that make up a mixture retain those properties. In a mixture of iron and sulfur, for example, black iron granules and yellow sulfur crystals can often be recognized. Also, the iron can be extracted from the mixture by means of a magnet, or the sulfur can be dissolved out with carbon disulfide. One part ...
Sulfur is pale yellow, odorless, brittle solid, which is insoluble in water but soluble in carbon disulfide. In every state, whether gas, liquid or solid, elemental sulfur occurs in more than one allotropic form or modification; these present a confusing multitude of forms whose relations are not yet fully understood.. In 1975, University of Pennsylvania scientists reported synthesis of polymeric sulfur nitride, which has the properties of a metal, although it contains no metal atoms. The material has unusual optical and electrical properties.. High-purity sulfur is commercially available in purities of 99.999+%.. Amorphous or plastic sulfur is obtained by fast cooling of the crystalline form. X-ray studies indicate that amorphous sulfur may have a helical structure with eight atoms per spiral. Crystalline sulfur seems to be made of rings, each containing eight sulfur atoms, which fit together to give a normal X-ray pattern.. ...

CONCLUSIONS 1.) The refinery database that has been generated shows that refinery fuel gas (RFG) varies widely in inorganic, organic and sulfur content. 2.) The existing refinery analytical techniques are not capable of accurately measuring all of the sulfur compounds in RFG at the low levels that are now of interest in the field. 3.) Newly developed analytical methods are indicating that significant levels of sulfur species other than HzS, such as Carbonyl Sulfide (COS), Carbon Disulfide (CSz), Dimethyl Disulfide (DMDS) and Mercaptans (RSHs) are present in RFG streams. 4.) Existing refinery amine systems typically remove 99.5 + % of the inlet HzS. The average sulfur content in the existing RFG database is 180-250 ppmv, based on the updated measurement techniques. 5.) The different sulfur removal processes that were investigated vary considerably in their abilities to remove specific sulfur compounds. 6.) No praYeD single technology was identified that can reduoo typical RFGs to 40 ppmv ...

We present an experimental and theoretical study of resonant inelastic x-ray scattering (RIXS) in the carbon disulphide CS 2 molecule near the sulfur K-absorption edge. We observe a strong evolution of the RIXS spectral profile with the excitation energy tuned below the lowest unoccupied molecular orbital (LUMO) absorption resonance. The reason for this is twofold. Reducing the photon energy in the vicinity of the LUMO absorption resonance leads to a relative suppression of the LUMO contribution with respect to the emission signal from the higher unoccupied molecular orbitals, which results in the modulation of the total RIXS profile. At even larger negative photon-energy detuning from the resonance, the excitation-energy dependence of the RIXS profile is dominated by the onset of electron dynamics triggered by a coherent excitation of multiple electronic states. Furthermore, our study demonstrates that in the hard x-ray regime, localization of the S 1s core hole occurs in CS2 during the RIXS ...
The cytochrome P450 enzyme CYP2E1 occurs in many parts of the human body (skin, nose, heart, brain, lung, liver, kidney etc.), but is most concentrated in the human liver. It makes up only about 7% of the total P450 enzymes in the liver.[16]. CYP2E1 accounts for approximately 7% of total CYP450 in the human liver.. Many sulphur-containing agents block this enzyme, such as carbon disulphide, diethyldithiocarbamate, and disulfiram.[16]. ...

The roots of cardiovascular diseases amount to a medical tangle, in large part because of so many contributing factors. Physicians routinely ignore the basic reasons why heart disease develops; namely, poor eating habits, obesity, and a lack of physical activity. Instead, they focus on symptomatic treatments, such as reducing cholesterol levels. Unfortunately, statins create an illusion of protection, while setting the stage for complacency and a panoply of short- and long-term side effects. Why bother eating healthier foods, losing weight, or exercising when a tiny pill will lower your cholesterol and supposedly solve everything? Nearly everyone has heard that elevated blood levels of cholesterol are a cause of heart disease. Elevated cholesterol is certainly a sign that something is awry, but the evidence that cholesterol itself causes coronary heart disease is flimsy at best. (Calcium forms part of the fatty deposits that form inarteries, but we are not exhorted to consume less calcium!) Most ...
Cardiovascular disease is actually a general term used for conditions that affect the heart or even the blood vessels. CVD is associated usually with the accumulation of fatty deposits right inside your arteries, called atherosclerosis. There would certainly be a rise in the risk of blood clotting. CVD could be related to the damage to your arteries present in the heart, brain, eyes, and kidneys. Cardiovascular disease is actually one of the major causes of disability and death in many nations today. Here are some kinds of cardiovascular diseases.. Ischemic Heart Disease. Ischemic Heart Disease is supposed to be the most common kind of CVD in many industrialized nations across the globe. It is associated with blood circulation issues to your heart muscle. A partial blockage present in one or even more of your coronary arteries could lead to a short supply of oxygenated blood (ischemia) resulting in symptoms like dyspnea or shortness of breath and angina or chest pain. A full blockage of one of ...
