摘　　要： 实验采用分光光度法以东莞市5个不同公园为研究对象,对公园灰尘污染状况和重金属的形态分布特征进行了研究。结果表明:东莞城市公园灰尘中Cu、Zn、Cr的平均含量分别为627.4、4733.1、2874.1mg/kg,其平均含量均超过东莞市土壤重金属元素的背景值,分别为背景值的36.9、92.8、56.9倍,可见东莞城市公园灰尘的重金属污染较为严重,其中Zn污染最严重。 The experiment was conducted on 5 different parks in Dongguan city by spectrophotometric method,the dust pollution and the morphological distribution of heavy metals in the park were studied.Result showed the average contents of Cu,Zn and Cr in the dust of Dongguan city Park were 627.4,4733.1 and 2874.1 mg/kg,the average content exceeded the background values of soil heavy metal elements in Dongguan city,which were 36.9,92.8,and 56.9 times as the background values respectively,it can be seen that the heavy metal pollution of dust in Dongguan City Park was more serious,of which Zn pollution was the most serious.
