作者调查三组接触多氯联苯(PCBs)的工人,其中228人从事大功率电容器制造,39人从事变压器维修。用个体采样器测定空气中PCBs浓度,并测定皮肤污染PCBs水平。检查的临床和生化指标有下列各项:血红蛋白、血细胞压积、白细胞计数及分类;血清钙、无机磷、葡萄糖、尿素氮、尿酸、胆固醇、总蛋白、白蛋白、总胆红素、碱性磷酸酶、乳酸脱氢酶、 The authors investigated three groups of workers exposed to PCBs, 228 of them manufacturing high-power capacitors and 39 of them working on transformer repairs. The concentration of PCBs in the air was measured using individual samplers and the levels of PCBs contaminated on the skin were determined. The following clinical and biochemical indicators were examined: hemoglobin, hematocrit, leukocyte count and classification; serum calcium, inorganic phosphorus, glucose, urea nitrogen, uric acid, cholesterol, total protein, albumin, total bilirubin, Phosphatase, lactate dehydrogenase,
