The concentration and distribution of dissolved Cu, Zn, Cd, Ni, Pb and Fe, and Cu, Zn, Cd, Ni, Pb, Cr, Fe, Si, Ca, Mg, Mn and K in suspended matter have been determined in the rivers Porong and Solo and in Strait Madura (East Java), during the dry- and wet-monsoon periods. Based on element/Al ratios, the suspended matter supplied by each of the two rivers can be traced offshore. The main source of material supplied to the coastal area is the Solo river. The distribution of the trace-metal content in suspended matter collected in the rivers can be described as a mixture of metal-rich, organic-rich particles and a metal-poor, detrital fraction. Due to the presence of mud barriers at the river mouths, particles with high trace-element contents are trapped in the estuaries. Compared to European rivers the dissolved trace-metal concentrations in these rivers are relatively low. The dissolved concentrations of the different trace elements in Strait Madura show no uniform distribution pattern during the two sampling periods.
