متن کاملIncidence of cancer among vinyl chloride and polyvinyl chloride workers.
The results of a follow up study of the incidence of cancer and the mortality in a cohort of 454 male workers producing vinyl chloride and polyvinyl chloride are presented. The study population was restricted to employees with more than one year's work experience in the study plant between 1950 and 1969 and the cohort was followed up from 1953 to the end of 1979. Twenty three new cases of cance...
متن کاملVinyl chloride and polyvinyl chloride exposure and occupational lung disease.
S everal recent reports,12 and one in this issue (see page 828), have contributed new observations on pulmonary disease in vinyl chloride (VC ) -and polyvinyl chloride (PVC) -exposed patients. Earlier reports, a few even preceding the identification in 1974 of vinyl chloride as a human carcinogen (with hemangiosarcoma of the liver the marker tumor, but most probably not the only tumor), had cen...
متن کاملIncidence of cancer among workers exposed to vinyl chloride in polyvinyl chloride manufacture.
Based on results from two previous studies where an excess of melanomas was found in a cohort of workers exposed to vinyl chloride (VCM), a follow up of the incidence of cancer in the same cohort of 428 workers was carried out to scrutinize whether or not the excess could be confirmed by new cases. The total number of deaths in the study group from 1953 to the end of 1993 was 132 v 141 expected...
متن کاملInfluence of Temperature on the Ultrasonic Degradation of Poly(vinyl acetate) and Poly(vinyl chloride)
This study investigates the effect of temperature on the ultrasonic degradation of polyvinyl acetate and polyvinyl chloride in chlorobenzene. The time evolution of molecular weight distribution was determined using gel permeation chromatography. Continuous distribution kinetics was used to obtain the degradation rate coefficients. The rate coefficients decrease with increasing temperature, and ...
