磷化锌的性状及毒性作用:磷化锌是效果很好的毒鼠剂,由红磷与锌粉共熔成磷化氢与锌盐作用制备而成,为深灰色或似黑色有熌光的粉末状物质,有特殊的磷化氢气味或大蒜样气味。比重较重(4.72～4.76),不溶于水和酒精,稍溶于油类,遇酸易分解成有剧毒的磷化氢气体。在干燥状态下比较稳定,受潮后会逐渐分解放出有毒的磷化氢,放置过久会失效,但在一个月内分解不多。大灰鼠的致死量为每公斤体重15～30毫 Properties and toxic effects of zinc phosphide: zinc phosphide is very effective rat poison, made of red phosphorus and zinc powder co-melt into phosphine and zinc salt, which is dark gray or black with calendering Powdery substance with a special smell of phosphine or a garlic-like odor. The proportion of heavy (4.72 ~ 4.76), insoluble in water and alcohol, slightly soluble in oil, met the acid easily decomposed into highly toxic phosphine gas. In the dry state is relatively stable, will gradually decompose after damp release of toxic phosphine, placed too long will fail, but not much decomposition within a month. Large squirrel lethal dose of 15 to 30 milligrams per kilogram of body weight
