Abstract

Chlorophyll-a and its degradation products (pheopigment) contained in the sediment were determined to evaluate the eutrophication status in the downstream of Nakdong River. The chlorophyll-a and pheopigment concentrations of sediment ranged 11-646 mg $\mu \textrm m^{-2}$ (mean 172 mg $\mu \textrm m^{-2}$) and 48-1,564 mg $\mu \textrm m^{-2}$ (mean 454 mg $\mu \textrm m^{-2}$) over 11 sampling stations of the Nakdong River. The chloropigment concentrations in this local area were higher than other values reported previously and this river waters showed hypertrophic status in view of sedimentary chloropigment. Total chloropigment standing crops of sediment, which are the residuals after the longterm degradation, were 2.2-3.6 fold higher than chlorophyll-$\alpha$ contents of overlying water. The amounts of chloropigments of sediment suggest a large contribution of phytoplankton to the sediment. While chloropigment standing crops are evaluated with organic-C and nitrogen contents, the algal contribution to the carbon and nitrogen pool of the sediment were estimated to be approximately 30% and 40%, respectively.
