《沉寂的春天》这本书一出版,DDT就被停用了。
维基百科上有背景:
1、《寂静的春天》(英语:Silent Spring),又译作《沉寂的春天》[1],作者是美国海洋生物学家雷切尔·卡森(英语:Rachel Carson),于1962年出版。[2]美国最高法院大法官威廉·道格拉斯曾为《寂静的春天》英文版作序。这本书促使公众普遍关注农药与环境污染。《寂静的春天》促使美国于1972年禁止将DDT用于农业上。
2、DDT,又作滴滴涕,学名双对氯苯基三氯乙烷(Dichloro-Diphenyl-Trichloroethane),化学式:(ClC6H4)2CH(CCl3)。白色晶体,不溶于水,溶于煤油,可制成乳剂,对人类毒性低,曾经是最著名的合成农药和杀虫剂。后来人们发现DDT不易降解,积累下来对鱼类和鸟类生存繁殖不利,破坏生态平衡,因此在世界大部分地区已经停止使用DDT,只有少数地区继续使用以对抗疟疾。
