摘要

///The assessment of the spatial-temporal variation of regional environment contamination is very important for monitoring the environment quality variation and contamination trend. 330 sediment samples were collected in Dexing area and analyzed for As, Hg, Cd, Cr, Zn, Cu and Pb in 2004. Heavy metal levels were determined using inductively couple plasma-atomic emission spectrometry and X-ray fluorescence spectrometry. The results show that there existed only slight contamination of As, Cd, Cu and Pb in 1989, which was mainly concentrated within a small area along the middle-lower courses of the Dexing River and that there were different degrees of contamination of As, Cd, Zn, Cu and Pb in sediments in 2004, especially in the areas of the Dexing River, Dawu River and middle-lower reaches of the Le’an River, which were rarely contaminated in 1989.
