โœฆ Synopsis

The epiphytic lichen Parmelia caperata was used systematically as a bioaccumulator of radionuclides in the Travale-Radicondoli geothermal field (central Italy). The results showed that radioactivity in this area is not different from that of other non-geothermal areas and that the exploitation of geothermal resources should not cause an enrichment in radioactivity. However, the survey also revealed a negative association between total fl radioactivity in lichens and the distance from geothermal power plants, so that the latter may represent a source of local radionuclide pollution.

Natural emissions of Hg are attracting increased interest both for their environmental implications and for possible applications in the exploration of mineral, petroleum and geothermal fields. However, daily and seasonal fluctuations in concentrations of Hg in the atmosphere, caused by meteorologic
