河南省济源市一个体工厂于2002年12月在生产过程中发生急性砷化氢中毒,造成9人中毒,死亡1人。时过不久,巩义市一个体企业发生同样的中毒事故,造成2人中毒。 砷化氢属高毒类,为某些工业在生产过程中所产生的废气。多种金属(如锌、锡、锑、铅、铜等)矿石中常含有硫化砷。含砷矿石在冶炼、加工、储存过程中遇酸(硫酸、盐酸)、湿均可产生砷化氢。另外使用乙炔生产合成染料,氰化法提炼金、银等也可产生砷化氢。故中毒可见于多种行业,而
A body factory in Jiyuan City, Henan Province, developed acute poisoning of arsine in the production process in December 2002, resulting in the poisoning of nine people and the death of one person. Soon after, a body of Gongyi City, the same poisoning incidents occurred, causing two poisoning. Hydrogen arsenide is a high toxic, for some industries in the production of waste gas generated. A variety of metals (such as zinc, tin, antimony, lead, copper, etc.) ore often contain arsenic sulfide. Arsenic ore smelting, processing, storage process met acid (sulfuric acid, hydrochloric acid), wet can produce arsine. In addition, the production of synthetic dyes using acetylene, cyanide method of extracting gold, silver, etc. can also produce arsine. It can be seen in a variety of poisoning industry, and
