Are there any Black Doms out there? If you are a black malelooking for a black sub, pleaseconsider me. Theriault, Hilda Iturra, and Suzanne Gingras To better define the association between exposure to vinyl chloride monomer VCM and the occurrence of birth defects, this epidemiological study was made Full service massage Chilliwack county Shawinigan, Quebec, Canada, where a vinyl chloride polymerization plant has operated since Birth-defect rates in Shawinigan during Mael last 15 years were compared with rates in three other communities, and seasonal and spatial variations in Shawinigan's birth-defect rate were correlated with estimated VCM concentrations in the environment.
Shawinigan had an excess of birth defects which fluctuated seasonally in a way that could correspond to changes in VCM concentration in the environment. Mothers who gave Malf to malformed children were younger on average in Shawinigan than in the comparison communities. However, there was no excess of stillbirths in Shawinigan, the excess in birth defects involved most systems, and owrkers in birth-defect rates among school districts could not be accounted for by estimates of VCM in the atmosphere.
The occupational and residential histories of parents who gave birth to malformed infants were compared with those of parents of normal infants. The two groups did not differ in occupational exposure or closeness of residence to the vinyl chloride polymerization plant.
Introduction Vinyl chloride monomer VCM is carcinogenic in man and other animals and mutagenic in microbial assays, Drosophila, yeast, mammalian cells, and man. VCM generates mutations primarily through one of its metabolites, chloroethylene oxide, and with the involvement of Shawinigwn microsomal enzymes.
Although miscarriages and fetal losses among the wives of workers exposed to VCM have been studied, such effects remain undocumented. VCM was found in the fetal and maternal blood and the amniotic fluid of pregnant rats after exposure to air containing VCM; two studies of VCM teratogenicity in animals failed to demonstrate fetal malformations, but Male sex workers Shawinigan increased fetal death rates. It is processed into polyvinyl chloride PVC; a plastic through polymerization reac- tions in autoclaves.
