在环境卫生学分析监督问题中,作者首先提出研究污染物的转化问题.这一问题是十分迫切的,因为物质在环境理化因子作用下发生转化,导致毒性较原始物质高的化合物生成.例如,空气中苯在理化因子作用下可生成众多(达20种)的化合物,其中有一些高毒性化合物.水中物质在氯化、臭氧化、煮沸、废水生物净化和其它方程净化时也发生转化,生成许多化合物,甚至高毒性化合物.因此,分析监督若只针对原始物质,则在生活区中检出原始物质浓度不大,就会
In the analysis of environmental hygiene supervision, the author first proposed the study of the conversion of pollutants.This issue is very urgent, because the material under the influence of environmental and physical and chemical factors, resulting in higher toxicity than the original material generated compounds.For example, Under the action of physico-chemical factors, benzene in the air can generate many (up to 20) compounds, some of which are highly toxic compounds, which are also converted when chlorinated, ozonated, boiled, purified from waste water and other equations are purified Many compounds, and even highly toxic compounds.Therefore, if the analysis of supervision only for the original material, then detected in the living area of the original substance concentration is not, it will
