摘    要:通过对冶炼厂综合堆渣场周边25个地表水、8个浅层地下水和19个稻米样品中重金属Cu、Zn、Pb、Cd、As含量的测定,发现该区地表水受到Cd、As的污染,在水作和旱作时超标率均在40.0%以上;浅层地下水受到Cd、Pb的威胁。稻米受到重金属Cu、Pb、Cd、As的复合污染,其中Cd污染最严重,超标率达100%,重度污染率达76.9%,其最高含量为标准(0.2 mg/kg)的37.6倍;其次为Cu、As、Pb,其超标率分别为38.5%,23.1%和15.8%。

关 键 词:综合堆渣厂  水环境  稻米  重金属污染  评价

Abstract:Heavy metals content were detected in 25 surface water samplers,8 shallow groundwater samples and 19 rice samples around the spoil area of the smeltery,revealing the content of Cu,Zn,Pb,Cd and As in the samples.The results showed that surface water was polluted by Cd and As,over 40.0% of the samples exceeded the concentration of official standards when the water was used for crops in both paddy and upland.Shallow groundwater was under threat.And rice was contaminated by Cu,Pb,Cd and As.Especially,the pollut...
Keywords:Spoil area  Water quality  Rice  Pollution of heavy metals  Assessment
