重庆某化工厂污染土壤的环境毒理学分析

Environmental Toxicology Analysis of Contaminated Soil in A Certain Chemical Plant in Chongqing

以重庆某化工厂污染土壤为研究对象,测定其成分,分析环境毒理学,考察其环境毒理行为。结果表明:污染土壤中含有烃类、氯及重金属等污染物质。在当前的评估指标下,该污染土壤应仅视为有毒,但不含各类致癌物质,不具有诱变风险,对性繁殖能力、生育能力、人体发育、母乳喂养没有任何影响,对目标器官不具有特定毒性,没有急性毒性风险,没有皮肤腐蚀性或皮肤刺激性风险,所以不会造成眼溃疡,对皮肤和呼吸道没有致敏性。污染土壤的环境危险风险为慢性毒性2类。污染土壤毒性较小,所以可以对其进行较好的资源化开发利用。

With a chemical plant polluted soil in Chongqing as the study object, through determination of its components and environmental toxicology analysis, the environmental toxicology behavior was examined. The results showed that there are some pollutants such as organic compound chlorine and heavy metals. In the current evaluation indicators, the contaminated soils should be only considered as noxious, be- cause there are no carcinogenic product, no mutagen product, no having effect on sexual reproduction and fertility or human body develop- ment, no having risk on or through human breast feeding, no having risk of specific toxicity on target organs（ STOT）, no having risk of acute toxicity, no having risk of skin corrosion or skin irritation, no having risk of the contaminated soileyes lesions, and no sensitizing for skin, breath, and so on. Moreover, the environment hazard risks of are rated chronic toxicity category 2. Therefore, there is a little toxicity of the contaminated soil. which can be a good resource for their development and utilization.
