Biological availability of sediment phosphorus inputs to the lower Great Lakes
In this study, river water samples were collected from several major tributaries to the Lower Great Lakes during storm runoff events in the spring and early summer of 1980 and 1981. Suspended sediments from these samples were subjected to a chemical fractionation sequence of NaOH-CDB-HCl, as well as algal bioassay analyses of sediment P bioavailability using the Dual Culture Diffusion Apparatus (DCDA) technique of DePinto. Sediments from several of the bioassy experiments were reconcentrated after the bioassays and resubjected to the chemical fractionation sequence. Several other forms of P inputs to the Lower Great Lakes were also analyzed for chemical composition and/or bioavailability.
