Experimental and statistical investigations on atmospheric heavy metals concentrations in an industrial area of Southern Italy

In this paper we present experimental protocol and statistical procedures for evaluating atmospheric concentrations of TSP and heavy metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn) in the area of Tito Scalo (PZ, Southern Italy), a small industrial site, far from urban areas and surrounded by agricultural and naturalistic sites. In order to characterise the concentrations level and the temporal pattern of each pollutant, we have analysed data collected in two field surveys (April-December 1997, April-December 1998) with univariate and multivariate statistical methods. Furthermore we have investigated the relationships between pollutants concentrations and meteoclimatic parameters (temperature and rainfalls).
