Multivariate analysis of pollution sources in Moravian-Silesian region

Methods of multivariate statistical analysis were used for identification of influence of industrial pollution sources on the air quality in Moravian-Silesian Region (MSR), the Czech Republic. Atmospheric concentrations of Cd, Pb, Co, Cr, Ni, Mn, Fe, Zn, Cu, Sb, V, Sr and As were monitored at 40 localities in MSR during the summer 2014. Cluster analysis divided the localities into 3 clusters. The cluster I is characterized by highest concentrations of all analyzed elements. Cluster I corresponds to contamination produced by element association Co-Cr-Ni-Mn-Fe. The 12 localities in cluster II are situated geographically in the area between Ostrava, Bohumin, Karvina, Orlova, Cesky Tesin and Havirov together with localities from cluster I. The cluster III contains localities with the lowest load. Most of localities are situated in region north-west of Ostrava, region of the Jesenik Mts, with exception of the locality Ostravice, Celadna.
