Metals concentration of insect and plant were useful for evaluating metal contamination and
were proposed to be an effective index as metal contamination of river. Heavy metals of water, river insect and
water plant were studied in order to clarify influence of geological condition on water, insect and plant metal
contamination. Cu, Co, Cr and Ni concentrations of river water were lower than those of insect and plant. Cu
and Co concentrations in river insect and water plant were affected by the Cu mines because their
concentrations were high in the Cu mine area. Cr and Ni concentrations in river insect and water plant were
affected by serpentinite because their concentrations were high in the serpentinite area. It was found that metals
concentrations in moss and plant root were effective indicator for the influence of geological condition because
Cu and Ni concentrations of plant root and Co and Cr concentrations of moss indicated highest concentration
and wide range.
