This report has been assigned to the ECOLOGICAL RESEARCH series. This series 

 describes research on the effects of pollution on humans, plant and animal spe- 

 cies, and materials. Problems are assessed for their long- and short-term influ- 

 ences. Investigations include formation, transport, and pathway studies to deter- 

 mine the fate of pollutants and their effects This work provides the technical basis 

 for setting standards to minimize undesirable changes in living organisms in the 

 aquatic, terrestrial, and atmospheric environments.
