玉林市典型工业区重金属铅污染的调查研究

以玉林市一些典型工业区的土壤为研究对象,用岛津AA-6601F原子吸收分光光度计测定土壤中全量铅和有效态铅含量,并对铅含量状况进行分析和评价.结果表明:这些工业区的土壤铅含量明显高于国家土壤背景值,按土壤环境质量评价的二级标准,已达轻度污染程度,土壤有效铅含量也比较高,都达到铅全量的20%以上,其中玉柴、环西大桥桥底的南流江畔、化肥厂附近农田、化肥厂排水沟旁、玉林地区饲料厂附近、市纸类制品厂(排水沟旁)、东校区外德兴造纸厂排水沟旁这7个区域中土壤有效铅含量超过铅全量的1/2.

An Analysis of Pollution of Heavy Metal Plumbum on Typical Industrial Area of Yulin City

Taking the soil in a typical industrial area in yulin as an sample, the content of soil heavy metal Pb was determinated by AA-6601F atomic absorption spectrophotometer. The analysis of soil heavy metals Pb was discussed in this paper. The results show that the total contents of Pb are higher than national background value obviously and have reached the criterion of slight pollution according to the second standard of soil environment quality. The all available Pb in soil samples were reach to 20%, and the s...
