Trees are widely used for biomonitoring and filtering air in industrial, urban, and rural areas. This research was undertaken to examine accumulation capacities of macroelements (Ca, K, Mg, Na) and trace metals (As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Zn) in needles and bark of Pinus sylvestris and leaves and bark of Quercus petraea growing in the vicinity of the chlor-alkali plant PCC Rokita in Brzeg Dolny (Lower Silesia, SW Poland). Because Scots pine is well studied and considered a useful bioindicator, we have used this species as a base for comparison of the accumulation ability of sessile oak that shows some features of good bioindicator, but whose biogeochemistry was scarcely studied. Results showed that for both species leaves contained more macroelements (Ca, K, Mg), whereas the bark was richer in most trace metals (Cd, Cr, Cu, Fe, and Pb). However, trees studied differed with respect to element content. Oak bark and leaves were more effective in accumulating macro- and trace elements (bark Cd, Co, Cr, Cu, K, Mg, Mn, Na, Ni, Pb and leaves Ca, Cr, Cu, Fe, K, Mg, Na, Ni) than Scots pine tissues. Nevertheless, foliar metal accumulation index of these species was similar, suggesting that their overall ability to accumulate trace metals was similar.
树木广泛用于工业、城市和农村地区的生物监测及空气过滤。本研究旨在检测生长在布热格多尔内（波兰西南部下西里西亚省）的氯碱厂PCC Rokita附近的欧洲赤松针叶和树皮以及岩栎树叶和树皮中常量元素（钙、钾、镁、钠）和痕量金属（砷、镉、钴、铬、铜、铁、锰、镍、铅、锌）的积累能力。由于欧洲赤松已得到充分研究且被视为一种有用的生物指示物，我们以该树种为基础，比较具有一些良好生物指示物特征但生物地球化学研究较少的无梗花栎的积累能力。结果表明，对于这两个树种，树叶中常量元素（钙、钾、镁）含量更高，而树皮中大多数痕量金属（镉、铬、铜、铁和铅）含量更丰富。然而，所研究的树木在元素含量方面存在差异。与欧洲赤松组织相比，无梗花栎的树皮和树叶在积累常量和痕量元素（树皮中的镉、钴、铬、铜、钾、镁、锰、钠、镍、铅以及树叶中的钙、铬、铜、铁、钾、镁、钠、镍）方面更有效。尽管如此，这些树种的叶片金属积累指数相似，表明它们积累痕量金属的总体能力相似。
