摘要
酸沉降地区,土壤、植物汞污染已较明显,且随沉降物的增加而加重。与此同时,地下水、牛奶中Hg含量提高。此外,为中和土壤酸度而施用的渣肥,也使土壤含汞量提高3～4倍。
Hg pollution of soil and plant is increasingly significant with increase in acid precipitation in the investigated area Meanwhile, contents of Hg in groundwater and milk were elevated. Addition of coal cinder for neutralizing soil acidity increased soil Hg content by 3-4 times.
