| 摘 要： | 武汉市硚口区某小区在企业搬迁遗留场地上建设而来,所在场地经二次开发利用后的土壤环境质量状况还不清楚。为此在小区场地布设8个采样点,采集24份土壤样品,在分析镍、铜、镉、铅、砷、汞6种重金属元素和苯并a]芘、石油烃、六六六、滴滴涕等4种有机污染物含量的基础上,采用污染指数法评价土壤环境质量。分析结果表明,土壤中上述10种污染物的含量分别为33.44×10-6~48.76×10-6、26.41×10-6~39.44×10-6、0.224×10-6~0.369×10-6、19.73×10-6~47.08×10-6、5.36×10-6~11.46×10-6、0.030×10-6~0.098×10-6、3.82×10-9~27.70×10-9、5.3×10-6~129.0×10-6、0.20×10-9~30.80×10-9、1.4×10-9~109.0×10-9;单项污染指数分别为0.223~0.325、0.013~0.020、0.011~0.018、0.049~0.118、0.268~0.573、0.004~0.012、0.007~0.050、1×10-5~16×10-5、0~0.030、0~0.017;研究区综合污染指数为0.333~0.369。研究区当前的土壤环境质量属于清洁水平。

| Abstract: | A areola in Qiaokou District of Wuhan City is constructed on the site of enterprise relocation.The soil environmental quality of the site after secondary development and utilization is not clear.For this purpose,24 soil samples are collected from 8 sampling sites in the areola.Based on the analysis of 6 heavy metal elements(nickel,copper,cadmium,lead,arsenic and mercury)and 4 organic pollutants(benzo(a)pyrene,petroleum hydrocarbon,HCH and DDT),the soil environmental quality is evaluated by pollution index method.The analysis results show that the contents of the above 10 pollutants in soil is 33.44×10-6~48.76×10-6,26.41×10-6~39.44×10-6,0.224×10-6~0.369×10-6,19.73×10-6~47.08×10-6,5.36×10-6~11.46×10-6,0.030×10-6~0.098×10-6,3.82×10-9~27.70×10-9,5.3×10-6~129.0×10-6,0.20×10-9~30.80×10-9,1.4×10-9~109.0×10-9,respectively.The single pollution index is 0.223~0.325,0.013~0.020,0.011~0.018,0.049~0.118,0.268~0.573,0.004~0.012,0.007~0.050,1×10-5~16×10-5,0~0.030,0~0.017,respectively.The comprehensive pollution index of the study area is 0.333~0.369.The current soil environmental quality in the study area belongs to the clean level. |
