AIM To assess the effects of occupational exposure to carbon disulfide (CS2) concentrations below the threshold limit value (31 mg/m3) on the structural and the functional properties of the arteries, heart rate, blood pressure and lipids. METHODS Study subjects were 85 male workers in the viscose industry and 35 men without such exposure. The CS2 concentration was determined by personal activ...

In a cross-sectional study, prevalence of dysfunctions of the central nervous system was assessed in 134 male workers exposed to different levels of carbon disulfide (CS2) in a rayon viscose plant and compared to 38 non-exposed workers. In three groups of workers from the same plant with different levels of CS2 (heavy, intermediate, none) estimated by personal samplers, disorders in the central...

To determine relatively useful diagnostic procedures of carbon disulfide (CS2) poisoning in terms of validity and cost-effectiveness, several diagnostic tests are evaluated on 1,552 people by prevalence ratio (exposed/nonexposed), dose-response relationship, sensitivity and specificity, and the cost of the tests. Several symptoms with high kappa indices are found to be useful in various combina...

Gas chromatography/mass spectrometry revealed the presence of both carbon disulfide (CS2) and carbonyl sulfide (COS) on rat breath. Behavioral experiments indicated that rats exposed to an unfamiliar diet moistened with CS2, like rats exposed to an unfamiliar diet placed on the fur of an anesthetized rat, subsequently exhibited enhanced preference for the unfamiliar diet. Rats in experimental g...

Biofiltration of industrial carbon disulfide (CS2)-contaminated waste air streams results in the acidification of biofilters and therefore reduced performance, high water use, and increased costs. To address these issues, we isolated 16 extremely acidophilic CS2-converting Acidithiobacillus thiooxidans strains that tolerated up to 6% (vol/vol) sulfuric acid. The ecophysiological properties of f...

Molecular dynamics simulation studies were performed to investigate the structural and dynamic properties of liquid carbon disulfide (CS2) from ambient to elevated pressure conditions. The results obtained have revealed structural changes at high pressures, which are related to the more dense packing of the molecules inside the first solvation shell. The calculated neutron and X-ray structure f...

use of zinc and iron oxide are common in the desulfurization process from natural gas. in thisresearch, after determinations of the size and specifications through tem and xrd for each of the metaloxides, two different size ratios were used, 0.66 for zinc oxide and 0.142 for iron oxide. further, absorption of sulfur compounds in gas (hydrogen sulfide (h2s), carbonyl sulfide (cos), methyl mercap...

Abstract. Tidal salt marsh soils can be a dynamic source of greenhouse gases such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), well sulfur-based trace disulfide (CS2) dimethylsulfide (DMS) which play roles in global climate carbon–sulfur biogeochemistry. Due to the difficulty measuring coastal ecosystems (e.g., flooding, salinity), our current understanding is based on snaps...

A photonic crystal fiber with a hollow core filled carbon disulfide (CS2) is proposed as new source of supercontinuum light. We numerically study guiding properties modeled fibers including the dispersion and effective mode area fundamental mode. As result, octave spanning SC spectrum was achieved in wavelength range near-IR from 1.25 μm to 2.3 90 fs pulse energy 1.5 nJ at pump 1.55 μm. The are...

The social environment plays a critical role in smoking initiation as well as relapse. We previously reported that rats acquired nicotine self-administration with an olfactogustatory cue only when another rat consuming the same cue was present during self-administration. Because carbon disulfide (CS2) mediates social learning of food preference in rodents, we hypothesized that socially acquired...
