百草枯问世已五十余载,在国内应用也达30余年。因触杀性强、死草速度快、杀草范围广、应用空间大、无土壤残留等突出优点,近几年始终是第二大吨位农药品种,为农业安全生产发挥了巨大作用。但百草枯毒性极大,一旦中毒即被脏器吸附,无特殊解救药剂。据介绍,成人口服20%水剂5毫升就足以致死。近几年因冲动或误服百草枯水剂,已视为人类非正常死亡的重要杀手之一。 Paraquat has been around for more than 50 years and has reached more than 30 years in China. In recent years, it has always been the second largest tonnage of pesticide species, which has played a great role in agricultural safety production because of its strong contact ability, fast speed of dead grass, wide range of grass killing, large application space and no soil residue. But paraquat toxicity is extremely large, once poisoning is organ adsorption, no special rescue agent. According to reports, adult oral 20% aqueous solution 5 ml is enough to die. In recent years due to impulse or mistreatment of paraquat agents, has been considered as one of the important killers of human deaths.
