The use of bio-indicators and soils to evaluate depositions of contaminates in the soil in a micro area
The controlled landfill in poiatica (RE) was monitored using mosses, transplanted mosses and soils. The following trace elements were analysed in mosses and soils: Al, Hg, V, Cd, Cr, Cu, Ni, Pb and Zn. In order to better evaluate the depositions, some radionuclides were studied in soil samples (7Be, 137Cs, 226Ra, 40Ke, 210Pb). Normalization of moss and soil concentrations allows one to evaluate the Enrichment Factor (EF), i.e. the parameter which helps discriminating between anthropic and natural origin of elements in mosses. The results are particularly interesting, as they show there was no specific influence from the landfill, in terms of atmospheric depositions. This was the first time in Italy where traditional analytical techniques for Environmental Impact Assessment were coupled with bio-monitoring techniques.
