AB  - Environmental persistence is an important property that can enhance the potential 
      of a chemical substance to exert adverse effects and be transported to remote 
      environments. The persistence of organic compounds is governed by the rates at 
      which they are removed by biological and chemical processes, such as 
      biodegradation, hydrolysis, atmospheric oxidation, and photolysis. The 
      persistence workgroup in a recent Society of Environmental Toxicology and 
      Chemistry (SETAC) Pellston workshop (Pensacola, FL, USA, January 2008) focused on 
      evaluating persistence of organic compounds in environmental media (air, water, 
      soil, sediment) in terms of their single-medium degradation half-lives. The 
      primary aim was to provide guidance to authors and reviewers of chemical dossiers 
      for persistent organic pollutants (POPs) and persistent, bioaccumulative, and 
      toxic substances (PBTs) proposed for action. A second objective was to provide a 
      summary of the current state of the science with respect to POP fate assessment. 
      Assessing the persistence of chemical substances in the environment is not 
      straightforward. A common misconception is that, like many chemical properties, 
      environmental persistence is an inherent property of the substance and can be 
      readily measured. In fact, rates of degradation of a substance in the environment 
      are determined by a combination of substance-specific properties and 
      environmental conditions. This article addresses how persistence can be evaluated 
      based on an assortment of supporting information. Special attention is given to 
      several critical issues, including transformation products, nonextractable 
      residues, and treatment of uncertainty and conflicting data as part of a 
      weight-of-evidence assessment.
