ABSTRACT
We have analyzed the contents of copper, lead and cadmium in water,
sediments and eel populations of Piles river in an upstream rural area and a
downstream urban area. 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
