摘要：

Five different procedures of sediment decomposition were compared, for evaluating the one more appropriated for assessing anthropogenic metal pollution. Exchangeable-metal extraction in sodium acetate, weak extraction in hydroxylamine hydrochloride/acetic acid, moderate extraction in diluted hydrochloric acid, oxidising strong acid digestion and total decomposition with hydrofluoric acid were tested. The mildest sodium acetate attack, which gives also better account for the bioavailable metal fraction, is the more effective in enhancing differences between polluted sediments and nonpolluted ones. Copper, lead and zinc are the best indicators of trace metal pollution of surface sediments.
