以锌废渣为原料生产镉的主要职业危害是混合粉尘的空气污染。由于粉尘中个别成分毒性高而有关其作用特点的报道较少,作者进行了本实验研究。用提炼镉的原料—铜—镉精矿(40～42%锌、6～7%铜、2.5～3.0%镉、0.6～0.8%铅和砷、锡、镍、钴、铊等)粉尘对140只大鼠染毒,研究其病理作用。实验分三组进行:
The main occupational hazard of producing cadmium with zinc waste as raw material is the air pollution of mixed dust. Due to the high toxicity of individual components in the dust and the reports about its characteristics of action, the authors conducted this experimental study. Using the extracted cadmium dust - copper-cadmium concentrate (40-42% zinc, 6-7% copper, 2.5-3.0% cadmium, 0.6-0.8% lead and arsenic, tin, nickel, cobalt, Only rats were poisoned to study their pathological effects. The experiment was divided into three groups:
