| 摘 要： | 利用PUF被动采样装置,对珠江三角洲地区大气中有机氯农药(OCPs)进行监测.结果显示,广东省大气中有机氯农药主要是滴滴涕(DDTs)、六六六(HCH)及氯丹(Chlordane),其中DDTs约占总OCPs的54.5%;香港大气中农药残留主要是氯丹和DDTs,氯丹约占总含量的51.3%.珠三角地区大气中有机氯农药空间分布差异明显(580-5500pg·m-3),香港平均浓度远远低于广东省.另外,广东省仍有工业DDT在使用,造成广东省大气中有"新"的工业DDT输入;而三氯杀螨醇是香港大气中DDT高含量的重要来源;广东省和香港HCH主要源于林丹使用的残留,香港的Eastern及Tsuen Wan源于工业六六六使用的残留;珠江三角洲所有采样点的HCB含量较低,大气中HCB少量残留可能是HCB作为药物中间体的化学合成及HCB在大气中长距离传输的结果. |

| Abstract: | This was achieved using a PUF passive air sampling system,based on the Guangdong province and Hong Kong in Pear river delta(PRD)between Aug.15 and Oct.14,2005.The results showed residues of OCPs are DDTs(54.5%),HCH and chlordane in Guangdong province,Residues of OCPs are chlordane(51.3%)and DDTs in HK.Using the comparison of isomer and content of compounds bring forward origin of higher residues of OCPs in PRD.Dicofol and tech-DDT is source of higher concentration of DDTs in HK.Source of HCH is usage of hexachloro-cyclohexane in PRD and technique-666 in HK.Concentration of HCB is low in PRD.Residues of HCB in air is from agriculture production and chemosynthesis. |
