Abstract

This study aimed to determine the concentration of heavy metals (Cr, Fe, Co, Ni, Zn, and Pb) that accumulated in the lichen Dirinariapictaand in the ambient air of different industrial areas in Peninsular Malaysia. Heavy metal content was analyzed using wet digestion method with concentrated nitric and hydrochloric acids. Samples were analyzed using ICP-MS. Back trajectory analysis was conducted using the Hybrid Single-particle Lagrangian Integrated Trajectory model to track down the transportation routes of contaminants. Principle component analysis (PCA) was also performed to identify possible sourcesof heavy metals in ambient air where Dirinaria picta was sampled. Results showed that Fe accumulated the most, followed by Zn, Pb, Cr, Ni, and Co, in both locations. A significant correlation (p<0.05) was found between heavy metal concentration in the air and the lichen. Sumatra, Indonesia could be one of the possible sources of heavy metals in Malaysia. Motor vehicles/industries are the main source of pollutants in ambient air, followed by soil, sea spray, and the earth crust.
