对于慢性有机磷中毒问题,国内外学者几十年来一直存在着争论,其原因是多方面的。主要原因之一,是由于很多农药厂工人,接触农药品种很杂且经常更换,缺乏详细记录,对工人健康与接触情况未建立档案,因而对慢性中毒问题缺乏科学资料;另 For chronic organophosphate poisoning problems, domestic and foreign scholars have been there for decades controversy, its reasons are many. One of the main reasons is that many workers in pesticide factories are exposed to frequent and frequent changes in pesticide varieties and lack of detailed records. They have not established any records on the health and exposure of workers and therefore lack scientific information on chronic poisoning.
