This paper discusses the bioavailability of Lake Erie tributary sediment phosphate as determined by chemical extraction and algal uptake. This report includes the following: (1) Review of the literature on procedures to estimate biologically available sediment phosphate (BSP) including sequential chemical extraction, resin extraction, P desorption and various algal bioassay techniques; (2) Sequential chemical extraction of P from suspended sediments in Lake Erie drainage Basin tributaries; (3) Algal uptake of sediment P from several suspended sediments from Lake Erie Basin tributaries; (4) Conclusions from the project studies; and (5) Extrapolation and implications for the Lake Erie Basin.
