Abstract

The presence of acid rain in the remote Amazon rainforest of southwestern Venezuela suggests the possibility of long-range transport of industrial pollutants to that region. Heavy metal concentrations were analyzed in samples of bryophytes and epiphyllous organisms growing on leaves and on bark in this forest. Concentrations of Cd, Pb, Ni, and Cr were higher in leaves with epiphylls than in leaves without epiphylls. All heavy metal concentrations in bryophytes from the Amazon basin site were lower than in bryophytes from temperature zones. The results indicate that long-range transport of air pollutants from industrial centers to the remote Amazon basin is occurring at only extremely low rates. Heavy metal concentrations in bryophytes and epiphylls at this site may still be considered close to present day background levels.
