　　1984年12月2日子夜，位于印度博帕爾市郊的聯(lián)合碳化物公司農(nóng)藥廠，一個(gè)儲存45噸劇毒液體———異氰酸甲酯的貯罐壓力驟然升高，使閥門失靈，異氰酸甲酯外泄汽化，致3150人死亡，5萬多人失明，2萬多人受到嚴(yán)重毒害，15萬人接受治療，受此事件影響的多達(dá)150余萬人，約占該市總?cè)丝诘囊话?。又?003年12月23日，我國重慶市開縣高橋鎮(zhèn)發(fā)生特大天然氣井噴事故，由于噴泄出的天然氣中劇毒的硫化氫氣體濃度過高，造成243人中毒死亡，2142人不同程度中毒住院治療，引起了全社會的高度關(guān)注。</p><p><strong>　　破壞生態(tài)環(huán)境</strong></p><p> 　　1986年11月1日，瑞士巴塞爾市贊多茲化工廠?；穫}庫發(fā)生火災(zāi)，約30噸農(nóng)藥和化工原料流入了歐洲著名的萊茵河，使萊茵河受到磷酸和汞化物的嚴(yán)重污染，240多公里長的河道里漂起大量死魚，河水不能使用。有關(guān)專家曾經(jīng)指出：該次事故將使萊茵河污染治理工作至少倒退15年，并對河流生態(tài)造成長期的影響。</p><p> 　　又如1991年的海灣戰(zhàn)爭導(dǎo)致有關(guān)國家的油井、貯油設(shè)施及化工企業(yè)遭到破壞，大量外泄的原油嚴(yán)重污染附近海域及岸上設(shè)施，導(dǎo)致大批海鳥和魚類死亡，油井、貯油及煉油等設(shè)施火災(zāi)的濃煙籠罩了大片城市及鄉(xiāng)村上空，污染的煙云飄移至南歐，甚至喜馬拉雅山南麓也下了黑色油水混合雨，給廣大地區(qū)的生態(tài)環(huán)境造成了極大的破壞。</p>
