MONITORING DURING TIME OF RELAPSES OF AN INCINERATION PLANT (original) (raw)

The principal purpose of this study is to quantify the baseline or "zero" levels of trace elements prior to the start up of the incineration plant of Parona (Pv) and subsequently, to evaluate, after 3 years in operation, possible changes in concentration of several elements and organic compounds in the immediate hinterland. The investigation covered about 65 km 2 . During 2002 and 2005, soil and moss samples were collected using standard procedures for the identification of the sampling points, and collection and treatment of the soil and moss samples. Soil samples were analysed for heavy metal, dioxin and furan contents; moss samples were analysed for heavy metal contents. The concentration of all elements studied, including dioxins and furans, are typical for agricultural areas exposed to anthropogenic pressures. However, differences in concentration were not observed between the two sampling periods. All values were below the limits of the D.L. Nr. 152, Column A. "Soil for residential/green use". In mosses, as well as in soils, no significant differences in concentration were observed between samples collected during the two campaigns. Study of the mosses allowed quantification of
