| Summary: | In our study, the concentrations of elements were determined in leaves and deposited dust of Quercus
robur and Celtis occidentalis which were washed with distilled water, rainwater and tap water. According to our results, each washing solutions had a significant effect on the elemental concentrations in the
foliage dust. The highest concentrations of aluminum, chromium, copper, iron, manganese and zinc were
detected in the foliage dust which was washed down with rainwater. The highest strontium and barium
concentrations were found in the foliage dust which was washed down with tap water. We observed
chromium and manganese accumulation in Q. robur leaves, while the concentrations of barium, copper
and strontium were the highest in C. occidentalis leaves. Our results demonstrated the effect of rainwater
on tree leaves which phenomenon occurs naturally. Rainwater may wash down the dry deposited foliage
dust from the leaf surface, but it also delivers a certain concentration of elements through wet deposition. |
