А CASE STUDY OF GREENING IN A RUSSIAN INDUSTRIAL CITY}, volume={23}, url={https://geomatejournal.com/geomate/article/view/3727}, abstractNote={<p>Urban trees can be effectively used as a biomonitor and phytoremediator of air pollution, but not all species are equally capable of filtering the air. Lead-containing PM<sub>2.5</sub> has raised severe public health concerns in industrial cities. PM<sub>2.5</sub> pollution episodes occur in Chelyabinsk (Russia) because of a zinc production plant located in the urban area. During zinc production from lead-zinc concentrates, the environment around the enterprise may become contaminated with lead. We measured the amount of Pb in PM<sub>2.5</sub> and Pb accumulated by the leaves of <em>Betula pubescens</em>, <em>Populus nigra L</em>., <em>Acer negundo L</em>. and <em>Pinus silvestris L.</em> from the 32 sites. The lowest value of Spearman’s coefficient was found for pine needles. The stomata of the needles were clogged with anti-icing agents that had accumulated over the winter. Pb found in the tree leaves correlated significantly with that found in the PM<sub>2.5</sub><em>. </em>The correlations of Pb concentration were maximal for birch tree leaves. The leaves of all three species studied − <em>B. pubescens, P. nigra, A. negundo</em> − can be used as phytoremediators of Pb air pollution in the Chelyabinsk urban area.</p>}, number={100}, journal={GEOMATE Journal}, author={Krupnova, Tatyana and Rakova, Olga and Berentseva, Susanna and Gavrilkina, Svetlana and Udachin, Valerii}, year={2022}, month={Dec.}, pages={70–77} }
