烧结炼铁过程中二噁英排放浓度及同类物分布研究

The Concentration and Distribution Research on the Congeners of Dioxins during the Sintering Process of Steel Industry

二噁英是一种高毒性持久性有机物,可对人体及周围环境造成深远影响。文章通过对国内某钢铁生产企业烧结工段废气及周边土壤二噁英物质的监测研究,得出二噁英排放浓度及厂区周边土壤中的污染程度。并依据废气及土壤中17种二噁英同类物的分布特征的相似性进一步推断出土壤中的二噁英主要来源于该厂的烧结工段。

Dioxins has been widely accepted as a high toxic persistent organic pollutant, it arouses severe and deep impacts to the human beings and surrounding environment. By monitoring and study on the waste gas and nearby soils during sintering process of a steel industry, to unfold the level of Dioxins contaminations of soils near the steel manufactural industry. Besides, according to the distribution characteristics of 17 Dioxins Congeners of waste gas and soils, putting forward to the contaminations of Dioxins in surrounding soils are mainly contributed by the sintering process of the industry.
