欧洲第二长河多瑙河,因罗马尼亚一座金矿氰化物的泄漏而严重污染。从金矿的沉砂池中泄出含氰化物的污染水10万m~3,沿途污染并毒死所有水生生物。这是自切尔诺贝利核电站事故以来中欧最严重的环境灾难。事故中多瑙河氰化物含量是法定最大含量0.1mg 的800倍。尽管氰化物含量事后很快就下降了,但迅速的稀释并不意味着污染已经过去,因为重金属会沉淀到泥沙中,它们分解缓慢,且覆盖面积很大,使300多 km 的河系受到严重污染,并至少要10a 才能消失。多瑙河沿岸国家委员会
The Danube River, the second longest river in Europe, is seriously polluted by the cyanide leak from a gold mine in Romania. From the grit chamber of the gold mine, cyanide-containing contaminated water is released from 100,000 m3 to 3 and contaminate and poison all aquatic organisms along the way. This is the worst environmental disaster in Central Europe since the Chernobyl nuclear accident. Danube cyanide content of the accident is the legal maximum content of 0.1mg 800 times. Although the cyanide content drops very quickly afterwards, rapid dilution does not mean that the pollution has passed as heavy metals precipitate into the sediment, which decomposes slowly and covers a large area, exposing the more than 300 km of river system Serious pollution, and at least 10 years to disappear.
