Determination of bioavailable phosphorus from water samples with low suspended sediment using an anion exchange resin method.

ABSTRACT: Measurement of phosphorus in surface waters for eutrophication studies is common. Phosphorus is commonly adsorbed to suspended sediment, but can desorb under certain conditions. Only a fraction of measured total phosphorus is bioavailable to aquatic organisms like algae, and for assessment, monitoring, and regulatory applications, researchers need to understand what proportion of total phosphorus in mixed water-sediment samples is bioavailable. Ion exchange resins have high capability of taking up dissolved ions like phosphate (PO₄ ^3-) and a long history of use in examining bioavailable phosphorus in surface water runoff. Previous work using resins to quantify bioavailable phosphorus was undertaken in waters with high total suspended sediment (TSS) concentrations (200
