美国的农药产量约占全世界的1/2,最高年产量达73万吨(1975年),比过去30年(1945年以后)增加了40倍。美国60%以上的农药用飞机喷撒,致使污染范围(水,空气,土壤等环境)扩大,形成了严重的社会问题。美国环境保护厅在对农药及有害物质加强法制管理的同时,最近还进行了大规模的农药环境污染的现场调查和农药对健康的影响等调查。据加利福尼亚州调查统计,1973～1975和1977四年内,该州发生职业性农药中毒事故5,492例。其中1975年1,343例,全身性中毒占39%,皮肤疾患33%,眼疾患23%。据加利福尼亚和佛罗里达两个州的统计资料估计,美国一年内约发生一万例中毒事故,各医院每年要接收
Pesticide production in the United States accounts for about one-half of the world’s total. The highest annual output reached 730,000 tons (1975), an increase of 40 times over the past 30 years (since 1945). More than 60% of the pesticides in the United States are sprayed on aircraft, resulting in the expansion of the scope of pollution (water, air, soil and other environments), posing a serious social problem. The United States Environmental Protection Agency in the pesticide and hazardous substances to strengthen the legal management, but also recently conducted a large-scale pesticide environmental pollution on-site investigations and pesticide health effects survey. According to a California state survey, 5,492 occupational pesticide poisoning accidents occurred in the state in 1973-1975 and 1977. Of 1,343 cases in 1975, systemic poisoning accounted for 39%, skin disorders 33%, eye diseases 23%. According to statistics from the two states of California and Florida, it is estimated that in the United States, about 10,000 poisoning accidents occur in a year and each hospital receives
