狄氏剂

"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。"

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。

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。

Increasing number of chemicals have been found to be estrogenic or possessing other endocrine disruptive effects. Among them are some organochlorine pesticides and other organochlorine chemicals, such as DDT and its metabolite p, p'-DDE, kepone, toxaphene, dieldrin, and PCBs, dioxins, and furans.

现在已经有越来越多的化学物被发现具有雌激素样作用或其它内分泌干扰作用，其中有相当一部分为有机氯农药或其他有机氯化合物，如滴滴涕及其代谢产物p，p'-DDE、开蓬、毒杀芬、狄氏剂以及多氯联苯、二恶英和呋喃类等。

Dieldrin is related to aldrin, and its toxicity to earthworms is similar.

狄氏剂与艾氏剂有关，对蚯蚓的毒性是相似的。

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 ester s.

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。

They then exposed laboratory mice to low, but "environmentally relevant" dosages of dieldrin - about 1 to 3 milligrams per kilogram.

然后，他们暴露在实验室的老鼠低，但&环保&的有关剂量狄氏剂-约1至3毫克每公斤。

The effects of aldrin and dieldrin on the reproduction of B.

以17β-雌二醇为阳性对照，运用生命表技术和群体累积培养方法，评价了艾氏剂和狄氏剂对萼花臂尾轮虫生殖的影响。

Dieldrin, which was most commonly used to control agricultural pests and termites, was banned for most uses by the Environmental Protection Agency in 1974 after it was found to be harmful to fish and other wildlife.

狄氏剂，这是最常见的用来控制农业害虫和白蚁，被取缔后，为大多数用途，由美国环境保护局在1974年后，发现它仍然是有害的，以鱼类和其他野生动物。

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。
