摘　　要：对东莞市麻涌镇新基水系、东太水系、大步水系3条中小河流底泥中重金属含量应用污染负荷指数法进行了评估研究,为中小河流清淤疏浚、淤泥处理处置提供科学依据。结果表明:新基、东太、大步水系综合污染等级分别为III级、I级和II级;Cd、Cu污染较为普遍和严重。In order to provide scientific basis for dredging and sediment treatment to small and medium rivers, the heavy metal con- tent of river sediment sampled from 3 small and medium rivers in Machong Town are evaluated by using the Pollution Load Index. The results show that the pollution level of heavy metals in Xinjin river is III; Dongtai river is I while Dabu river is II. Particularly, the Cd and Cu pollution are common and serious.
