2、枯水期采集沟塘水、浅层井水、深层井水水样,对水样中的铅元素使用电感耦合等离子体质谱法(ICP—MS7500a)测定。运用健康风险评价模型对农村饮用水中铅元素所引起的建康风险进行初步评价,同时分析3种水源在丰、枯水期的健康风险差异。结果在158份水样中,铅元素的检出率为93.67,平均值为2.35/xg/L,水样超标率为1.27。水样中非致癌重金属铅引起健康危害的风险水平是7.54×1O。/a,丰水期明显高于枯水期(t=7.32,P3、浅层井水和深层井水。结论淮安市农村居民饮用水中铅含量有一定超标,但是非致癌风险均在可接受风险范围。关键词:农村居民;饮用水;铅;健康风险评价中图分类号:R123.9文献标识码:A文章编号:1006—9070(2014)05—0001—03DetectionandriskassessmentofleadintypicalruraldrinkingwaterinHuai’anHUWei,YANGMeng—xue,ZHANGQin,XUQiu—jing,HEYuan,wANGChuang,PANEn~chunHuai’a4、nCenterforDiseaseControlandPrevention,Huai’an223001,ChinaAbstract:0bjectiveTostudyleadconcentrationsindrinkingwaterandhealtheffectsontheruralresidentslivednearbyHuaiheRiverinnorthernJiangsuProvince.MethodsWatersamplesfromditchpond,shallowwells,deepwellswereres5、pec—tivelycollectedduringperiodsofhighflowandlowflowfrom28villagesof14townsin3countiesofHuai’anCity,whichloca—tedinHuaiheRiverBasin.Elementofleadinwatersampleswasdeterminedbyinductivelycoupledplasma—massspectrometry(ICP—MS7500a).Andhealthriskassessmentwasusedt6、oanalyzethehealtheffectsontheruralresidentsinthreewatersourcesduringhighflowperiodandlowflowperiod.ResultsIn158watersamples,thedetectionrateofleadelementis93.67,withameanconcentrationof2.35/ag/L.Theratioofsuper—scaleofwatersamplesis1.27.Thehealthhazardscausedb7、yheavymetalleadinwatersamplesinpersonalrisklevelwas7.54×lO一/a.Thehealthriskofhighflowperiodissignifi—cantlyhigherthanitoflowflowperiod(f=7.32,P8、eshallowwellsanddeepwells.ConclusionLeadconcen—trationsindrinkingwaterinruralareainHuai’anCityexceededthestandardtoacertaindegree,butthehealthhazardcausedbyitwasintherangeofaccepta
