摘　　要：矿业活动区环境重金属污染对人群健康的危害是人们关注的重大环境问题。以2009年某金矿区水土环境重金属污染区内的A村村民头发为研究对象,同时以环境相对清洁的B村人群头发中重金属含量为对比值。研究结果表明,污染区不同年龄段人群头发中的重金属平均含量具有一定的统计学意义,不同性别、不同年龄段人群头发中,Hg、Pb、Cd平均含量分别是对照区人发中的7.81倍、6.75倍和4.20倍。总体而言,污染区人发中重金属含量仍在持续累积。人发中高含量的重金属与人体健康存在较好的相关性,金矿区环境污染对人群健康危害严重。The harmful effect of heavy metal contamination on people＇s health in the mining area is an important environmental problemthathasarousedmuchdiscussion.ThispaperreportedacasestudyofvillageAsufferingfromheavymetalpollution.Hairswerecollect at random, and then heavy metal concentrations were analyzed during 2005 and 2009. The analytical results were compared with the analytical results of the samples collected at village B suffering from no contamination. The ratios show that the average heavy metal concentrationsatdifferentageintervalsshowstochasticlaw.AverageratiosofHg,PbandCdwere 4.83,6.68 and4.16 respectivelyduring 2009. The cumulative single indexes of Hg, Pb and Cd were the highest in the adult male, and the ratio sorting order of heavy metals from lager to lower are total index（7.81）, boy（7.20）, adult female（6.75） and girl（4.20）. Generally, the heavy metal concentrations are continually increased in the contamination area, and there is a good relationship between the high heavy metal content and people＇s healthrisk.Itisthereforeconcludedthatthecontaminationhasexertedaseriousthreattopeople＇shealthinthegoldminingarea.
