Study of The Status of Organochlorine Pesticide Residue in The Soil of Zhenjiang Region

2006年11月采集了镇江地区69个土壤表层样品,利用ASE萃取后使用GC(ECD)法测定样品中的BHC和滴滴涕的含量。结果表明,镇江地区土壤中的BHC的检出率不高,但是滴滴涕的检出率比较高;冲积平原的检出率高于林地和滩涂;蔬菜和水稻种植区域的污染比草地、灌木丛和林地要严重。

Gathered 69samples of surface layer soil, to be extracted by ASE and then be analyzed the contents of BHC and DDT by GC （ECD）.
