随着毒理学的进展,许多国家对多种毒物的毒性进行了研究,并制订了不少单个毒物的卫生标准。但是,环境中往往同时存在着多种毒物,因此必须对毒物的联合作用进行研究并制订混合毒物的卫生标准。在研究混合毒物的毒性之前,应先了解这些物质混合后所发生的理化反应及其对毒性的影响。混合毒物共存时如发生化学反应而产生
As toxicology progresses, many countries have studied the toxicity of many poisons and developed a number of hygienic standards for individual poisons. However, many kinds of poisons exist in the environment at the same time. Therefore, it is necessary to study the synergistic effect of poisons and formulate the hygienic standard of mixed poisons. Before studying the toxicity of mixed poisons, you should first understand the physical and chemical reactions that occur when these materials are mixed and their effect on toxicity. Mixed poison occurs when a chemical reaction occurs
