Abstract

 

EreÄŸli, a province with ıron-steel industrial activities, is situated on the coast of Black Sea in Northwestern Anatolia. Heavy metal pollution caused by industrial activities is a threat to environmental quality and human health. Allium cepa L. is a bioindicator due to its sensitivity to environmental pollution. Fe, Hg, Zn, Hg, Crshowed greater accumulation in its leaves in four different sampling points. A significant decrease at Hg and Pb concentrations was not seen in its leaves. This study showed that the leafy plants contaminated with toxic heavy metals during industrial activities and EreÄŸli’s air quality has been poor.

 

Key words: Heavy metal, bioindicator, ındustrial pollution, Western Anatolia.
