本文较系统地介绍了制订地面水中有害物质卫生标准的卫生毒理学方法;并根据巳有的卫生标准资料,分析了有害物耍的半数致死量(LD_(50))与毒作用阈,感官性状作用阈以及对地面水一般卫生状况影响阈浓度之间的关系。卫生毒理学研究的主要任务是确定有害物质长期对机体作用的条件下的最大无作用浓度。对于其毒性在文献中阐述尚不够清楚的某些化学物质,研究应包括急性、亚急
This paper systematically introduces the method of hygienic toxicology for establishing the hygienic standard of harmful substances in surface water, and based on the existing hygienic standard data, analyzes the half-lethal dose (LD_ (50)) and toxic effect threshold The threshold of action, and the threshold level of influence on general sanitation of surface water. The main task of the study of health toxicology is to determine the maximum non-effect concentration of harmful substances under long-term effects on the body. For some of the chemicals whose toxicity is not clearly understood in the literature, the study should include acute, subacute
