狄氏剂

Over the next few decades, however, dieldrin and other banned pesticides should dissipate in the environment and become less of a factor in the development of Parkinson's disease, according to Miller.

在未来的几十年里，不过，狄氏剂和其他违禁农药应散失在环境中，并成为较少的一个因素，在发展柏金逊病，据苗。

Although no longer used, dieldrin can persist in the environment for decades and move up through the food chain, particularly in dairy products and meats, to humans, Pennell said.

虽然不再使用，狄氏剂，可长期存在于环境中，几十年来，并提出了通过食物链中，特别是在乳制品和肉类，给人类， pennell说。

"Our current study clearly shows that pesticides such as dieldrin appear to accelerate or exacerbate the already underlying disease," said Gary Miller, Ph.D., an associate professor of environmental and occupational health at Emory University.

&我们目前的研究清楚地表明，农药如狄氏剂，似乎加速或加剧已经潜在疾病的，&加里表示，米勒，博士，副教授，环境与职业健康埃默里大学。

"One may get a jar-type attachment for the garden hose, for example, by which such extremely dangerous chemicals as chlordane or dieldrin are applied as one waters the lawn," she observed.

&可能得到一个花园水龙带的附属瓶装物，那些极度危险的如chlordane和狄氏剂之类的化学药剂就会在灌溉时喷洒到草坪上。&

Another recent study, by the same Emory/Georgia Tech team, found that fetal rodents exposed to dieldrin had brain alterations that made them more susceptible to Parkinson's-inducing toxins.

最近的另一项研究中，由同一埃默里/格鲁吉亚的高科技队伍，发现胎鼠暴露于狄氏剂过脑部改动，使得它们更易于受到parkinson's诱导毒素。

This paper studied four pretreatment methods by adding three different retention time organochlorine pesticides(α-BHC、Dieldrin、pp′-DDT) to fish sample and making different concentration(0.01、0.1、1),then using GC-ECD determinate its recoveries.

研究了用气相色谱——电子捕俘器法测定鱼肉中有机氯农药的四种不同前处理方法。通过向鱼样中加入三种不同保留时间的有机氯农药(α—六氯苯、狄氏剂、滴滴涕)，并测定三种不同浓度(0.01、0.1、1)时加标回收率。

Some organic insecticides are natural, such as rotenone, pyrethrins, and nicotine. Others are synthetic, such as chlorinated hydrocarbons (e.g., DDT, dieldrin, lindane); carbamates, related to urea (e.g., carbaryl, carbofuran); and parathions, organic phosphorus esters.

有机的杀虫剂可能是天然的，如鱼藤酮、除虫菊和尼古丁；或是合成的，如氯代烃类(例如，滴滴涕、狄氏剂、林丹)、氨基甲酸酯，与尿素有关(如氨基甲醯、灭多虫和卡甲喃)、巴拉松、有机磷酸盐。

Objective A multiresidue method based on solid-phase extraction andgas chromatography with electron capture detector was developed for thesimultaneous determination of 15 pesticides (Dichlorvos, Dimethoate,Parathion-methyl, Malathion, Parathion, Fenpropathrin, Lambda-cyhalothrin,Cypermethrin,Esfenvalerate,Deltamethfin,Quintozene,Dieldrin,Heptachlor,α-Endosulfan,β-Endosulfan) in drinking water.

目的：建立同时检测饮用水中15种农药残留的固相萃取-气相色谱分析方法，所检测的农药包括5种有机磷：敌敌畏，乐果，甲基对硫磷，马拉硫磷，对硫磷；5种有机氯：五氯硝基苯，狄氏剂，环氧七氯，α-硫丹，β-硫丹；5种拟除虫菊酯：甲氰菊酯，三氟氯氰菊酯，氯氰菊酯，氰戊菊酯，溴氰菊酯。

Use of endrin in fishery management.

利用异狄氏剂的渔业管理。

Recovery studies were performed at 0.05, 0.1, and 0.5 mg/L spiked levels of each POPs, and the recoveries obtained ranged from 81.99% to 100.60% with relative standard deviations between 2.37% and 18.48%. The detection limits of the method ranged from 0.1 to 5 ng/g for the different POPs except endrin, trans-chlordane and cis-chlordane.

不同浓度水平的添加回收率试验表明，25种持久性有机污染物的添加回收率为81.99%～100.60%，相对标准偏差为2.37%～18.48%，除异狄氏剂、反式氯丹和顺式氯丹的检测限分别为20，30和20 ng/g外，其他有机污染物的检测限为0.1～5 ng/g。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
