铬的职业危害受到国内外学者的关注。其化合物易溶于水,氧化性强,含铬废水、废气是重要的环境污染源。生产过程中的铬盐、尘、酸雾可经呼吸道、皮肤和胃肠道进入人体。目前趋向认为铬是一种致癌物,国外报导,铬化合物生产工人所见癌症多发生于呼吸系统。为探讨生产重铬酸钠(Na_2Cr_2O_7)过程中对工人健康的危害,于1985年4月对某厂(灌县化工厂)开展了卫生学调查,结果如下:该厂有职工195人,其中生产工人128人,男工92
Occupational hazards of chromium by domestic and foreign scholars attention. Its compounds are easily soluble in water, strong oxidizing, chromium-containing wastewater, exhaust gas is an important source of environmental pollution. Chromium salts, dust and acid mist in the production process can enter the human body through the respiratory tract, skin and gastrointestinal tract. Current trends that chromium is a carcinogen, foreign reports, chromium compounds produced by workers in the cancer occurred in the respiratory system. In order to explore the hazards to workers’ health in the course of producing sodium dichromate (Na_2Cr_2O_7), a hygiene investigation was carried out in a factory (Guanxian Chemical Plant) in April 1985, with the following results: The factory has 195 workers and workers, of which production 128 workers, 92 men
