Title: Lichens as bioindicators of aerial fallout of heavy metals in Zaria, Nigeria

Abstract

Lichens and other epiphytic cryptogams possess efficient ion-exchange mechanisms which enable many species to accumulate airborne metals and which probably contribute to their tolerating metals at concentrations high enough to cause death to other plant species. A direct relationship between the distribution pattern of lichens and the trace metal content of the surrounding air has been demonstrated. The present study used lichens to assess the aerial fallout of heavy metals from traffic in Zaria, northern Nigeria.
