Based on the testing and analyzing the organochlorine insecticides (such as HCHs, DDTs and dieldrin) and PCBs contents in the sediment and water body covered the sediment, this paper plots and describes the various organic pollutants distribution, simultaneously analyzes the organic pollutants sources according to the main pollution sources along the coastwise of Daya Bay.

本文通过对大亚湾海域上覆水和沉积物中有机氯农药(HCHs、DDTs和狄氏剂等)和多氯联苯等有机污染物含量的调查分析，分别对各有机污染物的分布状况进行了描述，同时根据目前大亚湾海域及其沿岸主要污染源的分布状况对各有机污染物的来源进行了初步分析。

The microwave-assisted extraction and Florisil solid phase extraction conditions were optimized. Under the optimum condition, the recoveries of 18 organochlorine pesticides (α-HCH,β-HCH,γ-HCH,δ-HCH, heptachlor, aldrin, heptachlor epoxide, endosulfan Ⅰ, p, p'-DDE, dieldrin, endrin, endosulfan Ⅱ, p, p'-DDD, o, p'-DDT, endrin aldehyde, endosulfan sulfate, p, p'-DDT, methoxychlor) were

优化了微波萃取和固相萃取柱净化条件，在最优条件下18种有机氯农药（α-HCH、β-HCH、γ-HCH、δ-HCH、七氯、艾氏剂、环氧七氯、硫丹Ⅰ、p，p'-DDE、狄氏剂、异狄氏剂、硫丹Ⅱ、p，p'-DDD、o，p'-DDT、狄氏剂、异狄氏剂醛、硫丹硫酸酯、p，p'-DDT、甲氧滴滴涕）的回收率在

They found volatilization of dieldrin tended to decrease as bulk density increased.

他们发现狄氏剂的挥发常随紧实度的增加而减低。

Hours later,these mice were decapitated,and the striatums were isolated from thebrains. The levels of dopamine, serotonin ( 5-HT ), homovanillic acid, 5-hydroxyindoleacetic acid ( 5-HIAA ) andnorepinephrinein the striatum were measured by high-performance liquid chromatography with electrochemical detection.

给3组小鼠分别喂食Dieldrin 50 mg·kg-1体重、Dieldrin 40 mg·kg-1体重和等量的生理盐水，3 h后处死小鼠，取纹状体匀浆用高效液相色谱-电化学检测法测定纹状体中多巴胺、5-羟色胺(5-HT)、高香草酸、5-羟基吲哚乙酸(5-HIAA)和去甲肾上腺素的含量。

Dieldrin at great dose can influence metabolism of DA in the striatum of mice and it may be one of the environ-mental factors inducing Parkinson's disease.

大剂量的Dieldrin可影响小鼠纹状体中DA的代谢，可能是致帕金森病的环境因素之一。

Results :Dieldrin(50 mg/kg body weight)can decrease the concentrations of DA and NA in the striatum of mice.

结果：喂食Dieldrin 50 mg·kg-1体重能降低小鼠纹状体中NA、DA及HVA的含量。

Relief efforts are proved most fruitful due to the effectiveness of certain pesticides. Dieldrin, the most effective locust killer, has been widely accepted in many countries.

第三段后半部分说大多数批准使用的杀虫剂效果都不明显，药效不强的杀虫剂使救援行动受到限制，而最有效的杀虫剂Dieldrin对人体有害而被禁用，所以其余几项不对。

Aim:To study the effect of Dieldrin on dopamine,serotonin(5-HT)and their metabolites. Methods : The C57-BL mice were divided into 3 groups,and were administrated orally Dieldrin 50mg/kg body weight,40mg/kg body weight andequal amount normal saline ,respectively.

目的：探讨急性Dieldrin中毒对C57BL小鼠纹状体多巴胺及其代谢产物含量的影响。

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。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
