Abstract

In order to assess the contribution of emission sources to the pollution of areas remote from industrial facilities, a combined approach of factor analysis and multivariate statistics was used for detecting the origin of heavy metal pollution in the lead – zinc mine environ. Three moss species (Hypnum cupressiforme, Scleropodium purum and Camptotecium lutescens) were used as biomonitors for determination the air-distribution of total 21 elements. The values for the metals contents were determined in moss samples by atomic emission spectrometry (ICP-AES). Data processing was applied with combinations of multivariate statistical methods: factor analysis, principal component analysis and cluster analysis, enabled discrimination of the lithologic and anthropogenic sources of heavy metals in the mosses. Higher contents of Pb and Zn were assumed (average values 60 and 75 mg kg-1, respectively). Also the contents of Cd, Cu and Mn were also assumed as anthropogenic influenced from the emission source, in order of their range values: 0.08-1.73; 4.11-21.4; and 55.5-376 mg kg-1, respectively. Multivariate factor analysis produced two factors (F1 and F2), expressed as statistically significant elements associations. The first factor associates the following elements: Ag, Ba, Cd, Cu, Fe, K, Mg, Mn, Mo, Na, Pb, Zn. The second factor associates the elements: Al, Cr, Li, and V. Principle component analysis was used for visualizing the correlations between factor components extracted from the elements contents (as variable) and the expressiveness of three moss species (as cases). No characteristic correlation was assumed to the element contents vs. individual moss species; higher contents of the anthropogenicaly introduced elements (Cd, Cu, Pb, Zn) positively correlate with the distance from the pollution source (lead-zinc mine).
