Componential analysis of extractives is important for better understanding the structure and utilization of biomass. In this investigation, wheat straw (WS) was extracted with petroleum ether (PE) and carbon disulfide (CS2) sequentially, to afford extractable fractions EFPE and EFCS2, respectively. Detailed componential analyses of EFPE and EFCS2 were carried out with Fourier transform infrared...

A 70-year-old man developed a slowly progressive cerebellar syndrome after having been exposed to carbon disulfide (CS2) in a viscose rayon plant for 27 years. Ataxia, dysmetria, dysarthria and adiadochokinesia appeared 7 years after retirement from work (at age 54), and were later accompanied by cognitive deterioration, dysmnesia, spatio-temporal disorientation, emotional lability, and paranoi...

carbon disulfide is used predominantly in the manufacture. it has affects the nervous system. in this study, the applicability of spme as a passive sampler for determination of carbon disulphide in air was studied. effect of sampler and environmental parameters on uptake of carbon disulphide was studied as well. four fibers were tested to select the best sampler for determine carbon disulfide i...

The objective of this study was to investigate the effect of occupational exposure to carbon disulphide (CS2) on the total cholesterol, blood pressure and prevalence of coronary heart disease (CHD). A cross-sectional study involving 252 viscose rayon workers and 252 age and sex matched controls was carried out. Depending on the job and specific work place, the CS2 concentrations were between 10...

Objectives—A prospective cohort study was initiated to clarify whether the current level of exposure to carbon disulphide (CS2) is low enough to prevent occurrence of subclinical health impairments or to ameliorate health eVects due to past high exposure. This paper describes the eVects of exposure to CS2 on the nervous and endocrine systems, and the subjective symptoms in a baseline observatio...

background : among the industrial activities that may cause odor nuisance problems, baking waste one is of the sources of bad odor, and therefore individuals complain from the industry. the aim of this study was to evaluation of pollutants released from poultry rendering plant and also performance of existing refiners in removing these pollutants.   methods : in this study, 66 air samples were ...

OBJECTIVES To understand the prevalence of polyneuropathy and correlations among the clinical manifestations, electrophysiological findings, and degree of exposure to carbon disulphide (CS2) in workers who were exposed to variable concentrations of CS2 in a viscose rayon factory. METHODS All the 163 workers received a detailed physical and neurological evaluation. Fixed point air samples were...

Exposure to carbon disulphide (CS2) in a viscose plant was measured by personal monitoring and by application of the iodine azide test and quantification of 2-thio-thiazolidine-4-carboxylic-acid (TTCA) in urine samples. A relation was found between the rise in urinary TTCA concentration during the workshift and the exposure index E1. The correlation (r) between the exposure index and the atmosp...
