铬及其化合物在工业上应用极广,多用于电镀、金属加工、印染、颜料、油漆、电池等工业。金属铬毒性较小,六价铬化合物或其盐类毒性很大。从 Machle 等的流行病学调查结果可以看出,美国、英国、日本从事铬酸盐生产的工人肺癌的发病率比对照组高得多,其肺癌死亡约占他们所调查对象全部死亡数的20～45%(对照组仅为1～2%);在
Chromium and its compounds in a very wide range of industrial applications, used for electroplating, metal processing, printing and dyeing, paint, paint, batteries and other industries. Metal chromium is less toxic and hexavalent chromium compounds or their salts are highly toxic. According to the epidemiological findings of Machle et al., The incidence of lung cancer among workers working in chromate production in the United States, United Kingdom and Japan is much higher than that of the control group. The death of lung cancer accounts for about 20% of the total number of deaths from their surveyed subjects ~ 45% (control group only 1 ~ 2%); in
