摘  要：
利用GC-ECD对环鄱阳湖区11个县市蔬菜地土壤中有机氯农药测定的数据,研究蔬菜地土壤中有机氯农药残留状况,并进行生态风险评价。结果显示,蔬菜地土壤中HCHs、DDTs、氯丹和六氯苯均有检出,且DDTs、HCHs的残留量较高,总有机氯农药含量范围为2.39～47.28μg·kg-1。从整体上分析,处于工业分布区域的土壤中有机氯农药含量高于其他区域。有机氯农药组成特征研究表明,该地区土壤中除个别采样点有机氯农药主要来自于早期残留外,大部分地区有新的污染源输入。与国内其他地区蔬菜地土壤相比,环鄱阳湖区蔬菜地土壤中有机氯农药含量较低。生态风险分析显示,环鄱阳湖区蔬菜地土壤中HCHs残留对于土壤生物的风险较低,而DDTs可能对鸟类和土壤生物具有一定的生态风险。

摘  要：
The organochlorine pesticide residue in vegetable soil and its ecological risk were evaluated within 11 counties and cities around the Poyang Lake.The results showed that HCHs、DDTs、Chlordane、HCB could be detected in the samples from vegetable soil,and the residual concentrations of DDTs and HCHs were especially higher.According to the distribution of OCPs components,which ranged from 2.39~ 47.28 μg·kg-1,the higher concentrations of total OCPs could be found in the industrial regions.Contamination of OCPs in soils in the area around the Poyang Lake were relatively lower than other areas.The eco-risk analysis showed that HCHs residues in the soils had no obvious influence on the geobiont there,while DDTs might have certain ecological risks on birds and geobiont.
