Both methods are time- and solvent-consuming during the processing. In this study, headspace solid-phase dynamic extraction was applied to exame 13 organochlorine pesticides (γ-HCH、heptachlor、δ-HCH、aldrin、heptachlor epoxide、o,p'-DDE、α-endosulfan、p,p'-DDE、dieldrin、endrin、o,p'-DDT、β-endosulfan、p,p'-DDT) in water and soils. That was a rapid, solvent free and no clean-up procedures technology.

本研究以近年发展之顶空微针动态抽取技术(Headspace solid-phase dynamic extraction， HS-SPDE)进行水及土壤中十三种有机氯农药(γ-HCH、heptachlor、δ-HCH、aldrin、heptachlor epoxide、o，p'-DDE、α-endosulfan、p，p'-DDE、dieldrin、endrin、o，p'-DDT、β-endosulfan、p，p'-DDT)检测方法建立，此技术为一无需溶剂萃取，不需净化之快速检测方法。
