异氰酸甲酯(MIC)是一种高毒化学物。在印度博帕(Bhopal)城,明显接触MIC的三十二万多人中,引起2000多人死亡,50000多人住院治疗。1984年12月3日凌晨,发生了MIC毒气泄漏事故,持续了约40分钟。在1.5～2小时内,毒气覆盖面积达60平方公里左右。毒气笼罩了人口约九十万的博帕城的大部分。搏帕事故显然是由MIC贮存罐进水导致剧烈的放热反应而引起的。据报道,安装在化工厂适当位置的几个安全保护装置失灵。约20吨MIC及可能的有毒反应产物逸入了大气。
Methyl isocyanate (MIC) is a highly toxic chemical. In Bhopal, India, more than 320,000 people were significantly exposed to MIC, killing more than 2,000 people and treating more than 50,000 hospitalizations. In the early hours of December 3, 1984, a MIC gas leak took place, which lasted about 40 minutes. In 1.5 ~ 2 hours, gas coverage area of about 60 square kilometers. Gas poisoned most of the city of Bhopal with a population of about nine hundred thousand. Phappa accident apparently caused by the MIC storage tank water lead to a violent exothermic reaction. Several safety guards installed in the chemical plant were reported to be malfunctioning. About 20 tons of MIC and possible toxic reaction products escape into the atmosphere.
