Summary

Practical & provocative, Bioavailability reviews prevalent understanding of the physical-chemical-biological mechanisms that control the bioavailability of both organic & inorganic contaminants in aquatic environments. *Discusses the complex issues that surround many regulatory issues *Emphasizes the need to identify & control that portion of the total concentration that is biologically available & can cause adverse effects, i.e., "active" *Examines the influence of dynamic factors, such as pH, alkalinity, & light on these mechanisms *Addresses the subject of speciation for both organic & inorganic contaminants
