To evaluate the biological activity of river sediments, we attempted to measure activities of enzymes in the sediments. The activities of amylase, cellulase, urease and phosphatase contained in Tama River sediments were measured using a simple method. This method was not influenced by pollutants in the sediment and reflected the activities of enzymes in the sediment. Sediment enzyme activity was closely related to the amounts of total organic carbon, total nitrogen, total phosphorus and respiration rate, and appeared to reflect microbial decomposition activity of organic substances in the sediments . In addition, protective effects of the sediment against the enzyme inhibitors were investigated.
