| 摘 要： | 对国内某钢铁企业厂区内土壤和烧结厂排放烟气中二噁英类物质进行了采样研究,得出土壤中二噁英类物质浓度范围是1.05~6.91pgⅠ-TEQ/g,平均值为3.22pgⅠ-TEQ/g;烟气中的浓度范围是0.23~0.48 ngⅠ-TEQ/Nm3,平均值为0.32 ngⅠ-TEQ/Nm3,给出了土壤和烟气中二噁英类物质形态分布特点,并根据形态分布存在的相似性推断出土壤中二噁英类物质主要来源于烧结厂烟气的排放。

| Abstract: | Flue gas in the sinter processes and soil samples from an iron and steel company were collected and analyzed in China. Results of dioxins concentrations in soil and flue gas samples ranged from 1.05 to 6.91pg I --TEQ/g with average of 3. 22pg I -- TEQ/g and from 0. 23 to 0. 48ng I -- TEQ/Nm^3 with average of 0. 32ng I -- TEQ/Nm^3 , respectively. Similar congener profiles based on two types of samples indicate the potential pollution on soil from stack gas emission of sinter plant. |
