: [目的 ]了解新兴工业开发区环境致癌物污染。 [方法 ]对某一工业开发区的空气、水、土壤等环境进行致癌物含量及其致突变性的测定。 [结果 ]大气的飘尘浓度多数超过国家标准 ,苯并 (a)芘浓度也接近或超过建议标准 ;自来水厂大气污染较重 ,自来水厂的沉淀池水和出厂水苯并 (a)芘含量增加且超标 ,其致突变强度也比水源水增加 ;土壤表层、水管积灰和树叶的苯并 (a)芘含量也增加 ,认为主要是大气污染物沉降的结果。 [结论 ]要降低环境致癌物浓度 ,首先是减少向大气排放有关污染物
: [Objective] To understand the environmental carcinogen pollution in emerging industrial development zones. [Methods] Determination of carcinogen content and its mutagenicity in air, water, soil and other environments in an industrial development zone. [Results] Most of the airborne dust concentration exceeded the national standard, and the benzo(a)anthracene concentration also approached or exceeded the recommended standard; the air pollution at the water plant was heavier, and the content of benzene(a) and thorium in the tap water and tap water of the water plant increased. Exceeding the standard, its mutagenic intensity is also higher than that of source water; the content of benzo(a)anthracene in the surface layer of the soil, the fouling of the water pipes, and the leaves also increases, which is considered to be the result of the deposition of atmospheric pollutants. [Conclusion] To reduce the concentration of environmental carcinogens, the first is to reduce the emission of relevant pollutants into the atmosphere.
