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
