【 摘 要 】

Sediment samplesfrom the Barigui River in Curitiba, south of Brazil, were evaluated followinggranulometric composition, organic carbon content, nitrogen, phosphorus andmetals such as zinc, lead, chrome, nickel and cadmium. The sediments shown highpercentage of phosphorus and nitrogen. Also the elemental organic C:N:P exceedthe Redfield ratios possible because the large amount of sewage input into river.The presence of metals is also high, however the metal cadmium has not beenfound. But the other metals are in greater concentrations and possibly the presenceof these metals is given by industrial and domestic sewage.
