摘要
本文通过对大冶有色冶炼厂以南农田Cd含量调查,发现该区农田均已遭受较为严重的Cd污染。该区农田水稻土Cd的平均含量为51.1mg/kg,最高竟达99.5mg/kg,污染指数Pi均>3,属严重污染。此外,还分析了造成如此高的Cd污染的原因,提出了一些综合治理对策。
Investigation of Cd contents in soils south to the Daye Smeltery revealed that farmland in that region was seriously contaminated with Cd. The Cd content of the paddy fields there was 51.5 mgCd/kg on average, with the highest reaching 99.5mgCd/kg and Pi above 3, which indicated that the paddy fields were seriously contaminated. Besides, causes of such a high contamination were investigated and on such a basis countermeasures are put forth in the paper for control of the contamination.
