砒霜(三氧化二砷)为高毒化学物品,其毒性甚大,大鼠经口的LD50为14.6 mg/kg,小鼠经口LD50为31.5mg/kg;人类口服10-15 mg可致急性中毒,60-300 mg可致死。2002年12月11日,广西某县境内发生一起运输车辆翻车引起的大量砒霜泄漏严重污染江河事故,在这起应急事故处理工作中,我们运用生石灰作为沉淀剂结合其它辅助措施,成功地对这起砒霜严重污染江河的事故进行了处理,达到了安全有效、简便易行、快速彻底的理想效果,现总结如下。1 事故发生的背景 一辆运输砒霜车辆因故翻车,车上装载的100桶(每桶200kg)共20吨砒霜的包装桶严重破损,大部分砒霜泄漏污染现场,
Arsenic trioxide (arsenic trioxide) is a highly toxic chemical, its toxicity is very large, the rat oral LD50 14.6 mg / kg, mouse oral LD50 31.5mg / kg; human oral administration of 10-15 mg can cause acute poisoning, 60- 300 mg can be fatal. On December 11, 2002, a large number of arsenic leaking caused by a rollover of a transport vehicle in a county of Guangxi Province caused serious pollution of rivers and rivers. In this emergency treatment work, we used quick lime as a precipitating agent and other auxiliary measures to successfully carry out this From arsenic poisoning to the serious pollution of the river’s accidents were handled, reaching a safe and effective, easy, rapid and complete ideal results are summarized below. 1 Accident Background A transport arsenic vehicle rollovers for some reason, the car loaded 100 barrels (200kg) a total of 20 tons arsenic cream barrels severely damaged, most of the arsenic frost leak contaminated sites,
