百草枯(1,1′—二甲基—4,4′—双吡啶氯化物)是四价双吡啶化合物之一,由于除莠作用强,而广泛地应用在农业上。双吡啶的除莠能力显然与其对电子亲和力有关,使电子以异常途径进入分子氧中,干扰大鼠肝细胞的组份、细菌和高等植物的正常功能。空气中的氧量增加时,可加强双吡啶除莠剂对植物的作用。因肺是特殊高组织氧压的器官,人和其他哺乳动物百
Paraquat (1,1’-dimethyl-4,4’-bipyridyl chloride) is one of the tetravalent bipyridine compounds and is widely used in agriculture due to its strong herbicidal activity. Herbicidal ability of bipyridines is clearly related to their electron affinity, allowing electrons to enter the molecular oxygen in an abnormal manner, interfering with the normal function of rat hepatocyte components, bacteria and higher plants. When the amount of oxygen in the air is increased, the effect of the dipyridyl herbicide on plants can be enhanced. Due to the lungs are particularly high tissue oxygen pressure organs, humans and other mammals
