摘要: 采用气相色谱-质谱联机方法(GC-MS)分析了东北某钢铁厂及周边居住区、风景区共11个采样点表层土壤样品16种多环芳烃(PAHs),结果表明,钢铁工业区16种PAHs(∑PAHs)浓度范围为3.39×103-1.54×105 ng·g-1,平均浓度3.21×104 ng·g-1;居住区∑PAHs浓度范围为587-6.70×103 ng·g-1, 平均浓度3.82×103 ng·g-1;风景区千山∑PAHs浓度385 ng·g-1.∑PAHs和Bap浓度均呈工业区>居住区>风景区趋势.与国内外其他研究结果相比,该钢铁工业区及其周边居住区土壤PAHs污染相对较为严重,11个采样点中有9个采样点土壤∑PAHs为严重污染,4个采样点苯并(a)芘(Bap)浓度超过加拿大土壤质量基准.利用特征比值法(Diagnostic Rate)和主成分分析法(Principal component analysis, PCA)对钢铁工业区及其周边地区土壤进行了源解析,结果表明,钢铁工业区土壤中PAHs主要来源于焦炉、燃煤、柴油燃烧等污染源,周边地区土壤除受工业污染源排放影响外,机动车汽油、柴油污染排放也有重要影响.

Abstract: Sixteen polycyclic aromatic hydrocarbons (PAHs) in 11 surface soil samples from an iron and steel plant in northeast of China and its surrounding areas, including residential and scenic areas, were analyzed by GC-MS(Gas Chromatography- Mass Spectrometry). The concentrations of ∑PAHs were 3.39×103-1.54×105 ng·g-1 with a mean of 3.21×104 ng·g-1 in the iron and steel industrial park, 587-6.70×103 ng·g-1 with a mean of 3.82×103 ng·g-1 in the surrounding residential area, and 385 ng·g-1 in the scenic. The concentrations of ∑PAHs and Bap in the industrial areas were the highest, followed by the residential area. Compared with other studies, the soils in the iron and steel industrial plant and its surrounding residential area were heavily polluted by PAHs. Nine of total 11 soil samples showed serious contamination by PAHs. Moreover, Bap concentrations in 4 samples exceeded the limit of Canada Soil Quality standard. Source analysis was performed using Diagnostic Rate and Principal Component Analysis (PCA) methods. The results showed that coal and diesel combustion contributed to PAHs pollution in the iron and steel industrial park. Moreover, vehicle gasoline and diesel emission was another important source of PAHs pollution in the surrounding area along with industrial emission.-
