Magne et al. (1974) made a somewhat similar study, but their emphasis was on the enhancement of the solubility of uranium in granites through the activity of heterotrophic bacteria. In their experiments microbial activity increased the amount of uranium in solution by factors of 2 to 97. Several organisms may have been involved. Bacillus licheniformis being the one species definitely isolated. Species of Thiobacillus were absent, so that the enhancement of solubility observed was probably quite unrelated to leaching processes depending upon the oxidation of pyrite. ...

After about three decades of extensive research on acid deposition some of the effects of acidity in regions devoid of any buffering capacity are well known. Leaching of calcium and mobilization of toxic aluminum from soils and often profound changes of plant and heterotrophic species composition in lakes, including the demise of the most sensitive fishes, amphibians and insects, are the most deleterious and indisputably established impacts. In contrast, the exact role of acid deposition in the reduced productivity and dieback of some forests remains uncertain. ...
