Trace elements monitoring in contaminated sites using mosses of the species Hypnum Cupressiforme
A controlled landfill in Poiatica (RE) was monitored using indigenous mosses of the species Hypnum cupressiforme. In this way it was possible to evaluate the depositions that took place in the last 7-8 years. Moreover, the landfill was monitored for a period of about one year by means of transplanted mosses, which allow to assess the variations in concentration with time. The elements analysed were: Cd, Cr, Cu, Hg, Ni, Pb, V, and Zn. Soil samples were also collected and analysed in order to evaluate any possible enrichment in concentration due to 'soil-effect'. The results did not show any particular influence from the landfill in the last 7-8 years. The enrichment factor showed that the concentrations of heavy metals in mosses was mainly due to the high vehicular traffic on untarred roads in the area of the landfill. The latter data were confirmed by the analysis of transplanted mosses.
