The effect of coating polymers on accumulation of airborne heavy metals by lichens

Research output: Contribution to journalArticlepeer-review

Abstract

Thalli of the fruticose lichen Ramalina duriaei (De Not.) Jatta collected at a rural unpolluted area were coated with synthetic coating polymers. The coated lichens were transplanted to a polluted site near a busy road intersection, for a period of 5 months. After the exposure period the content of Cu, Pb, and Ni in the thalli was measured. It was found that some of the coating polymers were effective in reducing the accumulation of Cu and Ni in the lichen thallus, but could not prevent the prevention of Pb. The coating treatment reduced chlorophyll degradation which occurred in the uncoated lichens.
