ABSTRACT
Macro air pollution effects refer to those consequences of air pollution exhibited on a large geographical scale, with the scale ranging from regional to global. Examples of such effects include acid rain, losses in the stratospheric ozone layer, and global warming. Acid precipitation causes multiple effects on both terrestrial and aquatic ecosystems. Acid precipitation can affect soil chemistry, leaching, and microbiological processes. Soil microorganisms and microbiological processes can be altered by acid precipitation. Two important effects of acid precipitation on soil are associated with changes in the leaching patterns of soil constituents and with the potential removal and subsequent leaching of chemical constituents in the precipitation. The consequences of climatic change on water quality include possible changes in the precipitation regime and the occurrence of acid rain. Direct consequences of climatic changes on water quality occur. For example, temperature increases can decrease levels of dissolved oxygen in the water.
