论文部分内容阅读
这是一篇于1971年7月20～23日在丹麦哥本哈根召开的斯堪的那维亚和德国药理学会联合会议上发表的论文。滴滴涕(DDT)自1943年问世,近30年来,世界上已喷洒了成百万吨。总的说来,在生产、操作和使用上是比较“安全”的农药。有机氯农药基本上不溶于水,而易溶于各种有机溶剂和油脂。由于其脂溶性和不易分解,故能长期潴留在生物(脂肪)材料中。由于其不易溶于水,易吸附于分散的微粒,以及不易被物理、化学和微生物等物质所分解,故能在土壤和环境中长期存留。
This is a paper published at a joint conference of the Scandinavian and German Pharmacological Society held in Copenhagen, Denmark from July 20 to July 1971. DDT has been around since 1943 and millions of tons have been sprayed in the world in the last 30 years. In general, pesticides that are “safe” in production, operation and use. Organic chlorine pesticides are basically insoluble in water, but soluble in various organic solvents and fats. Because of its fat-soluble and not easy to decompose, it can long-term retention in biological (fat) material. Because it is not easily soluble in water, easily absorbed in the dispersed particles, and not easily broken down by physical, chemical and micro-organisms and other substances, it can be long-term retention in soil and environment.
