【 摘 要 】

Sediment samples from the Barigui River in Curitiba, south of Brazil, were evaluated following granulometric composition, organic carbon content, nitrogen, phosphorus and metals such as zinc, lead, chrome, nickel and cadmium. The sediments shown high percentage of phosphorus and nitrogen. Also the elemental organic C:N:P exceed the 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 been found. But the other metals are in greater concentrations and possibly the presence of these metals is given by industrial and domestic sewage.
