Bioavailability Physical, Chemical, and Biological Interactions

    256 Pages
    by CRC Press

    Practical and provocative, Bioavailability reviews prevalent understanding of the physical-chemical-biological mechanisms that control the bioavailability of both organic and inorganic contaminants in aquatic environments.

  • Discusses the complex issues that surround many regulatory issues
  • Emphasizes the need to identify and control that portion of the total concentration that is biologically available and can cause adverse effects, i.e., "active"
  • Examines the influence of dynamic factors, such as pH, alkalinity, and light on these mechanisms
  • Addresses the subject of speciation for both organic and inorganic contaminants
