| 摘要: |
| 本文选取了辽宁省盘锦市红海滩6个采样点的沉积物, 通过测定其中重金属和石油各组分的含量, 调查盘锦红海滩的重金属和石油的污染情况。结果表明, 各采样点中除退化区的Cu和茂盛区的Pb含量高于《海洋沉积物质量标准》(GB 18668-2002)Ⅰ类标准外, 其他各区域重金属含量均低于(GB 18668-2002)Ⅰ类标准。茂盛区的植物必需金属Fe、Mg、K含量在36.9～46.1 g/kg之间, 高于退化区和光滩区的30.7～38.0 g/kg; 退化区和茂盛区的土壤样品含油浓度较高, 在1.6～5.2 mg/kg之间, 光滩区的土壤样品含油浓度较低, 为2.5 mg/kg, 均远低于(GB 18668-2002)Ⅰ类标准500 mg/kg; 退化区的土壤中多环芳烃各组分含量在0.4～51.8 ng/g之间, 相比于其他地区的0.2～25.0 ng/g较高, 而光滩区土壤中多环芳烃各组分含量在0.2～3.8 ng/g之间, 相比于其他地区的0.3～51.8 ng/g较低; 不同区域土壤正构烃的组成(C10～C35)基本相同, 但是分布特征存在较大差别。 |

| Abstract: |
| This paper chooses the soil at red beach in six sampling sites of Panjincity, Liaoning Province. It studied the pollution of heavy metals and oil in red beach by measuring the content of heavy metals and petroleum in sampling sites area. The results showed that the content of Cu in degraded areas and Pb in lush areas werehigher than that of marine sediment quality standard (GB 18668-2002) class I standard, the heavy metals content in other areas is lower than (GB 18668-2002) Class I standard. The content of plant essential metals Fe, Mg and K in the flourishing area is between 36.9-46.1 g/kg, which is higher than that of the degraded area and the light beach area of 30.7-38.0 g/kg. The oil concentration of soil samples in degraded area and luxuriant area is higher, between 1.6 and 5.2 mg/kg, and the oil concentration of soil samples in floodplain is generally low, was 2.5 mg/kg, but they are far lower than (GB 18668-2002) class I standard 500 mg/kg. The content of polycyclic aromatic hydrocarbons in soil was between 0.4 and 51.8 ng/gin degraded area is relatively higher than that of other areas of 0.2 to 25.0 ng/g, but the content of PAHs in the soil of luxuriant areais was 0.2-3.8 ng/g, which was relatively lower than that in other areas between 0.3 and 51.8 ng/g. The composition of soil normal hydrocarbon in different areas is basically the same(C10-C35), but the distribution characteristics are quite different. |
