Evaluating the Capability of Woody Plants to Capture Atmospheric Heavy Metals in Budapest

Urban green infrastructure planning plays an important role in aspects of pollution reduction, such as heavy metal trapping. However, the reduction effects are both influenced by different conditions each city and species-specific interaction trees pollution. Herein, we investigated three common urban woody plants (Acer platanoides L., Fraxinus excelsior L. Westhof’s Glorie, Tilia tomentosa Moench) Budapest to compare their trapping abilities from airborne leaf dust deposits leaves. All samples were deconstructed a wet digestion method. Four high traffic-related elements (Zn, Cu, Pb, Ni) determined using atomic absorption spectrometer (AAS). The results showed that relevant concentration all measured was constant species, namely Zn < Cu Pb Ni. Although total content deposit increased towards end one vegetation period, highest percentage summer season particulate matter sources varied season. These indicate ideal candidates for monitoring. evaluated loaded T. during sampling times, followed A. platanoides, least F. excelsior. A significant correlation between contents found (0.926 at p<0.01 level). Therefore, suggest tomentosa, which has better atmospheric trace element capturing capacity than thus it is option area.
