Abstract
Vapour levels of metallic mercury in the atmosphere of an abandoned mercury mine and distillation plant at Abbadia S. Salvatore (Mount Amiata, Tuscany, Italy) were detected by means of the mercury accumulation rate in leaves of azaleas located in 100 sampling sites. The response of azalea leaves to a constant mercury concentration in the air (30 ng/L) was calibrated in the field, in relation to indoor conditions. No significant methylation of mercury was found to occur in spontaneous vegetation or contaminated azalea samples. The volatilization of mercury at different temperatures and the use of bioconcentrators to detect mercury vapours in contaminated areas is discussed. © 1994.
