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...

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...

A highly sensitive and selective method for simultaneous determination of some hydroxyl group-containing endocrine disruptors, including bisphenol A (BPA), bisphenol B (BPB), bisphenol E (BPE), bisphenol F (BPF) and 4-nonylphenol (4-NP), was developed. The method consists of precolumn derivatization of the analytes, solid-phase extraction (SPE) and subsequent chromatographic analysis by high-pe...

Polyvinyl chloride (PVC) is made by polymerizing vinyl chloride monomer and is a plastic that softens on heating. The addition of a small amount (<5%) of plasticizer produces a hard PVC, whereas the addition of 30 to 50% plasticizer results in a soft PVC. Soft PVC is used to make several products, including chemical shoes, cables, gloves, hoses, and film. The principal component of PVC hose is ...

Investigations of the effect of the excitation light wavelength on the intensity distribution in the fluorescence band of l,4-diphenyl-l,3-butadiene (DPB) in polyvinyl alcohol) films (PVA) at 296 and 87 K for samples before and after heating to 423 K, and fluorescence lifetime measurements have shown that trans-trans and cis-trans conformers are responsible for the emission of fluorescence. The...

BACKGROUND Contact allergy to plastic gloves is rare. Benzisothiazolinone is a biocide that is mainly used in industrial settings. We first suspected delayed-type contact allergy to benzisothiazolinone from polyvinyl chloride (PVC) gloves in 2004. We looked through our medical records from 1991 to 2005 to find similar cases. OBSERVATIONS We found a total of 8 patients who are allergic to benz...
