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

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.

[Health status of workers in polyvinyl chloride processing plants. I. Evaluation of occupational exposure. Subjective and capillaroscopy studies. Conduction velocity in the motor nerves].

The examinations covered 255 workers of two polyvinyl chloride processing plants. All workers were subject to general medical examinations including electrocardiography. In a part of workers employed in the plant located in the Katowice Voivodeship, the dermatological tests and neurological examinations including testing the velocity of conduction in motor nerves were carried out and the selected group was subject also to capillaroscopy and dermatothermometry.
