乌梁素海水体与沉积物中半挥发性有机物污染水平及风险评估黄子晏1,2，张亚辉1，曹家乐1,2，杜士林1*，张瑾2，何连生11.中国环境科学研究院环境检测与实验中心2.安徽建筑大学环境与能源工程学院摘要为研究乌梁素海水体与表层沉积物中半挥发性有机物(SVOCs)的污染特征和风险水平，对乌梁素海7个点位的水体和沉积物样品进行检测分析。结果表明：水体与沉积物中SVOCs的总浓度为449.7～691.0ng/L及144.4～587.5µg/kg；多环芳烃(PAHs)和邻苯二甲酸酯(PAEs)是所有样品中发现的主要污染物；其他SVOCs未检测到或仅检测到微量。水体与沉积物中PAHs污染主要来自石油源及煤炭、生物质燃料燃烧混合来源；PAEs污染主要来自塑料和化工工业，以及生活垃圾；水体和沉积物中主要污染物的生态风险总体上呈低风险。从饮水和暴露接触的角度，乌梁素海呈现的健康风险水平较低。关键词乌梁素海；半挥发性有机物；水体；沉积物；风险评估中图分类号：X52文章编号：1674-991X（2023）02-0607-10doi：10.12153/j.issn.1674-991X.20220376Distributionandriskassessmentofsemi-volatileorganiccompoundsinwaterandsedimentofUlansuhaiNurHUANGZiyan1,2,ZHANGYahui1,CAOJiale1,2,DUShilin1*,ZHANGJin2,HELiansheng11.EnvironmentalAnalysisandTestingLaboratory,ChineseResearchAcademyofEnvironmentalSciences2.CollegeofEnvironmentandEnergyEngineering,AnhuiJianzhuUniversityAbstractInordertostudythepollutioncharacteristicsandrisklevelofsemi-volatileorganiccompounds(SVOCs)inwaterandsurfacesedimentsofUlansuhaiNur,waterandsedimentsamplesfrom7sitesweredetectedandanalyzed.ThetotalconcentrationofSVOCsinwaterandsedimentaryspeciesrangedfrom449.7to691.0ng/Land144.4to587.5µg/kg,respectively.Polycyclicaromatichydrocarbons(PAHs)andphthalateesters(PAEs)werethemaincontaminantcompoundsfoundinallsamples.OtherSVOCswerenotdetectedoronlytrace.PAHspollutioninwaterandsedimentmainlycamefrompetroleumsourceandmixedsourceofcoalandbiomassfuelcombustion.PAEspollutionmainlycamefromplasticsandchemicalindustryanddomesticwastes.TheecologicalriskofthemaincontaminantsinwaterandsedimentofUlansuhaiNurwasatalowlevelingeneral,andthehealthriskalsopresentedalowlevelintermsofdrinkingwaterandexposure.KeywordsUlansuhaiNur;semi-volat...
