| 中文摘要: |
| 采用快速溶剂萃取-氟罗里硅土柱净化-气相色谱/质谱联用法测定环境空气中 POPs 类有机氯农药及其降解产物。艾氏剂、狄氏剂、异狄氏剂、六六六、滴滴涕、七氯、氯丹、灭蚁灵及其降解产物的检出限为 2.0 ng ～4.6 ng,空白加标回收率为62.1% ～118% ,RSD为6.8% ～ 15.2% 。 |
| 英文摘要: |
| A method wasestablished to determineorgano - chlorinepesticidesofPOPsand theirdegradative productsin the ambientairby accelerated solventextraction - florisilpurify-GC/MS. The detection limitsofdri nox, dieldrin, endrin, BHC, DDT, heptamul, chlordane, dechlorane and theirdegradativeproducts were from 2.0 ngto 4.6 ng. The blank recoveries were from 62.1% to118% and the RSD were from 6.8% to15.2%. |
