Carbon disulphide poisoning in viscose rayon factories.
The manufacture of rayon by the viscose process exposes workers to the hazards of carbon disulphide (CS2) poisoning. When the viscose industry was started the toxicity of carbon disulphide was scarcely known among manufacturers, and the processes used were primitive; this resulted in many cases of CS2 poisoning in all those countries where viscose plants had been established. Since then, techni...
متن کاملPolyneuropathy induced by carbon disulphide in viscose rayon workers.
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...
متن کاملA follow-up study of coronary heart disease in viscose rayon workers exposed to carbon disulphide.
In 1967 two cohorts of 343 men each were formed and matched with respect to age, district of birth, and similarity of work. One cohort comprised viscose rayon workers with at least five years' exposure to carbon disulphide during any period between 1942 and 1967, and the other cohort consisted of workers from a paper-mill with no such exposure. The concentrations of carbon disulphide and hydrog...
متن کاملExposure to carbon disulphide and ischaemic heart disease in a viscose rayon factory.
The cohort of viscose rayon workers previously described by Tiller et al has been reconstructed and followed up to the end of 1982. The pattern of mortality at ages 45 to 64 for the extended period 1950-82 is similar to that described by Tiller et al for 1950-64. The spinners, the workers most heavily exposed to carbon disulphide, have a significantly higher mortality from all causes than the l...
متن کاملA morbidity study of viscose rayon workers exposed to carbon disulphide.
A historical cohort study of the morbidity of CS2 and control workers was carried out in a viscose rayon factory and an adjacent cotton mill. A total of 725 male workers was employed at the two factories on I May 1966. All records of medical treatment received by these men from general practitioners, hospitals, and plant clinics for the period from I May 1966 to 31 December 1970 were obtained f...
