摘　　要：通过采集珠三角东部城市生活垃圾焚烧厂、危险废物焚烧厂和医疗废物焚烧厂周边表层土壤和荔枝叶片样品,分析Cd、Pb、Hg、As、Cr、Cu、Ni、Zn和Co 9种重金属含量,研究了土壤重金属的含量水平及来源,以及叶片重金属的含量水平和富集系数。结果表明:研究范围内表层土壤Cd与垃圾焚烧厂和医疗废物焚烧厂关系紧密;As与医疗废物焚烧厂和危险废物焚烧厂关系紧密;荔枝叶片对Cd、Cu、Hg的富集系数较高。在焚烧厂周边环境的重金属污染调查中,Hg、Cd和As等应受到重点关注。The contents of nine selected heavy metals (Cd,Pb,Hg,As,Cr,Cu,Ni,Zn and Co)were determined and analyzed through collecting samples of the top soils and leaves of Litchi chinensis surrounding three solid waste incineration plants in the east of Pearl River Delta,including a municipal solid waste incineration plant,a hazardous waste incineration plant and a medical waste incineration plant,and the contents and sources of heavy metals in the soils as well as the contents and bioaccumulation factors of heavy metals in the leaves were also studied.The results showed that :in the top soils,Cd was strongly related to the municipal solid waste and medical waste incineration plants;whereas As was strongly related to the medical waste and hazardous waste incineration plants;the bioaccumulation factors of Cd,Cu and Hg in the leaves of Lichi chinensis were high.The above results indicated that Hg,Cd and As deserved more serious attention during surveys of heavy metal pollution in areas;surrounding the incineration plants.
