有机磷杀虫剂3911(又名甲拌磷、西梅脱)在国内试用于棉子处理,由于其残效期长,防治棉蚜效果好,并能兼治多种地下害虫,对促进棉花增产有良好效果,颇受棉农欢迎。但本品对哺乳动物的毒性很大(比1605、1059的毒性大数倍),非但毒作用带窄,且可经呼吸道、消化道及皮肤等途径侵入体内。因此研究使用3911拌、浸棉子和播种过程的劳动卫生问题具有一定的卫生学意义,同时也是生产和使用部门迫切希望解决的问题。
Organophosphorus insecticide 3911 (also known as phorate, cimex) trial in the domestic cotton treatment, due to its long-term effects of cotton aphid control effect is good, and can cure a variety of underground pests, to promote cotton yield Good effect, popular cotton farmers welcome. However, this product is highly toxic to mammals (several times more toxic than 1605,1059), not only has a narrower effect and can invade the body through the respiratory, digestive and skin pathways. Therefore, it is of certain hygienic significance to study the labor hygiene problem of using 3911 mixing, soaking cotton seed and sowing process, and it is also an issue urgently desired to be solved by the production and use departments.
