Abstract:

2006年3月,采集湖南省东北部7个地区蔬菜土壤样品,采用GC-ECD检测、GC/MS-MS确证的方法对土壤中20种有机氯农药进行分析,并探讨有机氯农药在蔬菜土壤中的残留现状及组成。结果表明,HCHs和DDTs检出率高达100%,残留量范围分别为0.15~16.80μg·kg-1和6.05~57.91μg·kg-1。OCPs的主要残留物是DDTs,占残留总量的70%以上。绝大部分地区土壤中α-HCH/γ-HCH比值大于1,DDT/(DDE+DDD)比值小于1,表明HCHs和DDTs主要来自于早期的使用,但岳阳和衡阳地区近期可能有新的DDTs农药输入。艾氏剂、狄氏剂、γ-氯丹和环氧七氯也有不同程度的检出。与国内外相关报道相比,HCHs和DDTs残留水平较低。
