• Abstract:

  The present work aimed the study of atmospheric deposition of toxic elements near to a tannery industry from black material deposited collected on leaf surfaces of cinnamon trees (Cinnamomum zeylanicum). Elements such as As, Ba, Cr, Cu, Fe, Ni, Pb, Sb, V, and Zn were analyzed by inductively coupled plasma mass spectrometry (ICP-MS). For comparison purpose two sites with similar black particles deposited on leaves away from tannery industry were considered. Results showed that toxic elements measured in the black particles collected near tannery area were significantly higher than those in comparison sites. Enrichment factors (EF) of As and Cr were markedly impacted by anthropogenic emissions, whereas the other elements were moderately/slightly enriched. Cluster analysis identified Cr element as anthropogenic source from leather industry, while As possibly attributed to wide use of pesticides and herbicides in agricultural practices. The results indicated that emissions from the leather industry and agricultural activities are the main source of pollution in this area
