Acid rain in an Amazon rainforest [PDF]
Tellus B, 1983 Acid rain is reported from the Amazon territory of Venezuela. The volume weighted average pHwas 4.7 for 70 storms sampled from January 1979 through February 1980. At this location,remote from point sources of industrial pollution, acid rain might result from naturalbiogeochemical processes in the rainforest, from global atmospheric pollution, or from ...
