AIMS To determine the concentrations of pentane (a marker of lipid peroxidation) and other volatile organic compounds in the breath of patients with schizophrenia. METHODS Volatile organic compounds were assayed by gas chromatography/mass spectroscopy (GC/MS) in 88 subjects--25 with acute schizophrenic psychosis, 26 with psychiatric disorders other than schizophrenia, and 37 normal volunteers...

Carbon disulfide (CS2) has been historically associated with the manufacturing of rayon, cellophane, and carbon tetrachloride production. This study is one of the first to identify elevated atmospheric levels of CS2 above national background levels and its mechanisms to dysregulate normal glucose metabolism. Interference in glucose metabolism can indirectly cause other complications (diabetes, ...

Carbon disulfide has long been recognized as a potent inhibitor of nitrification, and it is the likely active component in several nitrification inhibitors suitable for field use. The effects of this compound on Nitrosomonas europaea have been investigated, and the site of action has been determined. Low concentrations of CS2 (less than 400 microM) produced a time-dependent inhibition of ammoni...

Carbon disulfide (CS2) is a typical organic sulfur compound emitted from many industrial processes, such as petrochemical, smelting, et al. Chemical adsorption promising method for CS2 removal and Fe based adsorbents usually show excellent performance. Single-atom catalysts (SACs) always perform magical effects in various heterogeneous reactions. In this work, pyrolyzing coordinated polymer (PC...

Carbon disulfide (CS2) intoxication may induce peripheral neuropathy, encephalopathy, and cardiovascular diseases. In our studies, abnormalities of the peripheral nerves including clinical symptoms and electrophysiological findings were still present 3 years after cessation of CS2 exposure. The data indicate that CS2 neuropathy may persist for a period of time. The involvement of central nervou...

OBJECTIVES We conducted a 6-year cohort study to evaluate the relationship between carbon disulfide (CS2) exposure and reductions in the motor and sensory nerve conduction velocity (MCV and SCV) of the median nerve. METHODS Study subjects at baseline included 432 exposed workers and 402 unexposed workers. Among the exposed workers, 145 workers terminated CS2 exposure during the follow-up peri...

Carbon disulfide is the solvent of choice for eluting adsorption packages prior to analysis by GC/FID. In laboratories which utilize mass selective detectors instead of flame ionization detectors, diethyl ether, a much friendlier solvent, can be used in place of the CS2. No loss of sensitivity occurs, and there is a salutary impact on bench workers' health as well as on the aroma of the fire de...

Adsorbent tube samples are collected by drawing workplace air through either coconut shell charcoal or Anasorb 747 tubes with personal sampling pumps. Diffusive samples are collected by exposing either 3M 3520 Organic Vapor Monitors (OVMs) or SKC 575-002 Passive Samplers to workplace air. Samples are desorbed with 60/40 (v/v) N,N-dimethylformamide/carbon disulfide (DMF/CS2) and analyzed by gas ...

INTRODUCTION Occupational exposure to carbon disulfide (CS2) leads to inhalative and dermal uptake and thereby to internal exposure. In order to prevent occupational contact dermatitis, gloves and skin protection creams are used at the workplace. The aim of the study was the evaluation of the influence of personal skin protection and irritation on the internal exposure to CS2 of employees in th...

Reactions have been observed between excited ions of carbon disulfide and carbon disulfide, water, iodine and ethylene. The ions CS3\ C,S,+, C2S3\ H2OS+, CSI+, SI+, C2H : iS+ and C2H4S+ are formed in these reactions. An additional contribution to the C2S2+ ion results from reaction of CS+ with CS2 • The reaction of I2+ with CS2 leads to the ion CS2I+. Reactions of excited molecular ions have al...
