Detemination of heavy metal concentration in vegetation around cement factory of Behbahan by using plant bioindicators
One of the most important of pollution forms in cement factories is air pollution by dispersing particles to atmosphere. The particles are contained a certain amount of heavy metals.
The aim of present study is detection of heavy metals from dust of the Behbahan cement factory using Eucalyptus camaldulensis and Ziziphus spina-christi as biomonitoring tools. Sampling was carried out random systematic to determination of heavy metal (Cr, Ni, Cd and Pb) concentration in tree leaves and were measured by ICP-AES atomic absorption. Results were: - Average concentrations of metals Cr, Ni, Cd and Pb in Eucalyptus camaldulensis leaves 2.29, 11.64, 0.06 and 1.62 ppm respectively.
- Average concentrations of metals Cr, Ni, Cd and in Pb Ziziphus spina-christi leaves 1.66, 4.38, 0.04 and 2.07 ppm respectively.
The results showed heavy metal concentrations were different in plant species taken from different places and directions and species of the factory. The data showed only the mean of chromium and nickel metals on Eucalyptus camaldulensis and chromium on Ziziphus spina-christi was higher than world standard. Also the concentration of elements on trees was decreased with distance of the pollution source.
