BIOMONITORING OF LEAD POLLUTION ON THE URBAN FLORA
In this study, the first aim was to find out the measures of lead (Pb) as the heavy metal pollution in Sarajevo, Bosnia and Herzegovina. The second aim was to test if chicory, Cichorium intybus L., can be used as a biomonitor of heavy metal pollution. Twenty-eight sites (urban, suburban and rural) in Sarajevo were investigated during the summer period in 2010. Concentrations of Pb were determined in leaves and roots of Cichorium intybus L. and also in soils collected from a wide range of sites with different degrees of metal pollution. As a result of measurements, the highest values of lead accumulations in plants have been observed in roots as expected. The highest values were detected as 30.10 mgkg-1 dry weight in roots and as 28.20 mgkg-1 dry weight in leaves in the PMF garden in Pofalici. On the other hand, the highest value of lead was detected as 450.05 mgkg-1 dry weight in soil in Museum Garden. Theoretically it is expected to observe highest accumulation in soils, roots and leaves, respectively. After getting results, it is observed the relationship of lead accumulation among soils, roots and leaves as expected. Cichorium intybus L. was found to be a useful biomonitor in the determination of lead pollution. Key words: Cichorium intybus L., lead pollution, biomonitoring, Sarajevo
