The uptake rate and equilibrium time of organochlorine pesticides were obtained during the laboratory experiment. All the equilibrium time are 594 hours except that δ-BHC's is 234 hours and both p, p'-DDE and o, p-DDT's are 70 hours. Uptake rates of α-BHC, hexachlorobenzene,β-BHC,γ-BHC,δ-BHC, heptachlor, aldrin, heptachlor epoxide, p, p'-DDE, dieldrin, endrin, p, p'-DDD, o, p-DDT and p, p'-DDT are 0.061, 0.071, 0.098, 0.066, 0.033, 0.014, 0.007, 0.062, 0.108, 0.052, 0.029, 0.032, 0.061mL/h, respectively.

得出了有机氯农药在水相和半透膜之间分配的平衡时间和富集系数，平衡时间除δ-BHC为234h和p，p'-DDE、o，p-DDT为70h外，其余组分均为594h；α-BHC、六氯苯、β-BHC、γ-BHC、δ-BHC、七氯、艾氏剂、七氯环氧、p，p'-DDE、狄氏剂、异狄氏剂、p，p'-DDD、o，p'-DDT、p，p'-DDT富集系数分别为：0.061、0.071、0.098、0.066、0.033、0.014、0.007、0.062、0.108、0.052、0.029、0.032、0.061mL/h。

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。

Because the concentrations of heptachlor, aldrin, o, p-DDT, p, p'-DDE and p, p'-DDT in SPMD are lower than those in water, these contaminants are not suitable to be sampled by this SPMD. The results of field experiment done at the Liangshui river prove the feasibility of SPMD used in groundwater monitoring. But detailed work is needed to be done in order to explain some unusual field experiment results.

七氯、艾氏剂、o，p-DDT、p，p'-DDE以及p，p'-DDT组分在膜中的平衡浓度远小于它们在水中浓度，不适于用此种半透膜取样器进行富集；在凉水河岸边的野外实验结果也验证了半透膜装置监测地下水有机氯农药的可行性，但其个别组分的结果出现异常，需要在该地区进一步开展工作进行研究。

With the existence of additional carbon sources, sodium lactate, sodium propionate or sodium acetate, the faster pH rised, the faster p, p'-DDT dechlorinated, which indicate that the existence of short chain organic substrate supplies sufficient electron donors for the dechlorination process, and p, p'-DDT can obtain electrons more easily during the stage of pH rising.

并且由于p，p'-DDT的还原脱氯与细胞色素氧化酶及辅基FAD有关，外加碳源下p，p'-DDT的缺氧降解多数发生在体系pH值上升的阶段，且pH值上升较快时对应的p，p'-DDT缺氧降解较快，而在无外加碳源的体系中，由于可供p，p'-DDT还原脱氯的电子量限制了p，p'-DDT还原脱氯的速度，未发现上述现象。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides.
