Health status of workers of polyvinyl chloride processing plants. II. Results of various biochemical studies


, : Health status of workers of polyvinyl chloride processing plants. II. Results of various biochemical studies. Medycyna Pracy 35(1): 13-20

In 255 workers of two PVC processing plants no changes have been found in routine laboratory tests. No deviations have been found in blood serum, bilirubin, cholesterol, creatinine, nitric residue of urea, calcium and phosphorus, either. Similarly, the activity of acid phosphatase and gammaglutamylotranspeptidase was not changed. In most examined groups a slight statistically significant increase in ALAT activity has been found, in others--increase in the activity of AspAT and basic phosphatase. Workers exposed to lead did not exhibit any laboratory plumbism symptoms. On the other hand, a significant decrease in the activity of erythrocytes deltaaminolevulinic acid dehydratase has been found. The studies suggest that workers processing PVC most probably exhibit slight toxic liver lesion.
