All heavy metals were determined by an electrochemical method (PSA). Sediment analyses showed that concentrations of these heavy metals in the samples from rural upstream were higher than those from urban downstream, suggesting that the main source of metal pollution in Piles river was originated by agricultural activities. There were significant correlations between copper, lead and cadmium concentrations in e
