氯乙烯引起的健康危害及防护效果评估

评估氯乙烯(Vinylehlorid,VC)接触职工的健康情况。通过流行病学方法,对VC接触人群健康情况进行调查。通过暴露组和对照组临床症状和体征相比,暴露组的症状与体征检出率均高于对照组,其中头晕、手足麻木、皮肤干燥、四肢乏力的检出率明显高于对照组。白细胞下降、血红蛋白下降的检出率分别为6.4%、11.0%,明显高于对照组。VC暴露组人群血清的AH、HP、MG、CG显著高于对照组,具有统计学意义。暴露组人群血清中CAT、MDA、SOD、GSH、AST、ALT、ATP水平与对照组相比,具有统计学意义(P0.05)。

Appraisal on Vocational Health Hazards Caused by Vinylehlorid and the Protective Effect

Vocational health hazards of Vinylehlorid （VC） were evaluated. An investigation was carried out via epi- demiologic methods. Through comparison of both clinical symptoms and signs and symptoms of the exposed group and the control group, it was shown that both symptoms and relevance ratio of signs of the exposed group were higher than those of the control group, featuring evident relevance ratios of dizziness, numbness of the extremities, dry skin and limb weakness. Besides, the relevance ratio of white blood cell decreasing and hemoglobin decreasing was 6.4% and 11.0% respectively, higher than those of the control group. Serum examination results showed that AH, HP, MG and CG of the exposed group were prominently higher than those of the control group, which has a statistical signifi- cance. Also, CAT, MDA, SOD, GSH, AST, ALT and ATP of the exposed group have statistical significance （P〈0.05）.
