Abstract
The present study assesses time-series data derived from a 3-year monitoring campaign of heavy metals in atmospheric wet and dry depositions in a coastal forest ecosystem in central Italy. Monitoring atmospheric deposition is a key issue when evaluating the impact of anthropogenic sources, and their absolute and potential toxicities to humans and other living organisms. Information from a permanent assessment of heavy metals is therefore crucial for the evaluation of environmental quality. Time trends in heavy metal atmospheric concentrations in Castelporziano forest (Rome), a natural ecosystem in central Italy, are considered a reliable indicator reflecting differences in spatial and temporal distribution of pollution sources. Preliminary analysis of atmospheric depositions in various sites of the forest highlights the influence of anthropogenic factors and of transport processes in both the short- and long-range distances. Further studies are recommended to investigate the relation between atmospheric deposition, meteorological variables, and runoff tree water. The use of other heavy metal indicators from specific sources of pollution, such as arsenic, is also discussed.
