SYSTEMATIC REVIEW AND CASUAL FRAMEWORK FOR EVALUATING AIR POLLUTANT IMPACTS TO FRESHWATERS
The United States Environmental Protection Agency (EPA) is mandated under the Clean Air Act to periodically review the adequacy of the National Ambient Air Quality Standards (NAAQS), for human health and welfare, including effects on water and wildlife. Four of six criteria air pollutants have the potential to impact freshwater ecosystems. Deposition of oxides of nitrogen and oxides of sulfur affect biogeochemical and biological function of lakes and streams, while lead and particulate matter-associated metals and organics are toxic to some biota. The foundation for review of the NAAQS is the Integrated Science Assessment (ISA), containing a synthesis and evaluation of the most policy-relevant science developed from a systematic literature review, typically including thousands of papers documenting effects in ecosystems. Causality is evaluated based on evidence of pollutant exposure and effects from field and laboratory studies. EPA has developed a framework to provide a consistent and transparent approach for considering aspects of causality in the ISAs.
