Effects of Acid Precipitation on Elemental Transport from Terrestrial to Aquatic Ecosystems

摘要

Significant progress has been made in terrestrial-aquatic transport methodology. Several techniques and conceptual frameworks are available for assessment of acid rain effects on these transport processes. Using the anion mobility model, for instance, it is possible to assess the relative effects of acid rain vs natural, internal acid production on elemental transfer rates. However, further research is needed in order to quantify these effects on a regional scale for sensitivity assessments. Sensitivity must be defined as to what ecosystem and what effects are being considered. Criteria have been developed, but there is a major need for more information on natural acid production.
