In this investigation we focus on the concentration of elements in Viscum album and its host (Sorbus aucuparia) as bioindicators of urban pollution. These broadly widespread species, very common in polluted areas may provide important information to monitor environmental quality throughout the year, especially for V. album. Cd, Co, Cr, Cu, Fe, Li, Mg, Mn, Ni, Pb and Zn concentrations were measured in the leaves and soil of the tree S. aucuparia as well as in V. album, a semi-parasite living on this tree species. The tree and the semi-parasite were studied in the urban environment of Oława (SW Poland). This area was selected because of the influence of a zinc smelter on the level of metal pollution of soil and plants and to compare the ability of S. aucuparia and V. album to accumulate metals. V. album appeared to be a better bioaccumulator of Cd, Ni, Pb and Zn and a weaker accumulator of Co than S. aucuparia in less polluted sites of Oława. S. aucuparia was a better bioaccumulator of Cd, Ni, Pb and Zn and a weaker accumulator of Co than V. album in more polluted sites. Cluster analysis of Cd, Co, Cr, Cu, Fe, Li, Mg, Mn, Ni, Pb and Zn concentrations in plants distinguished sites with lower and higher pollution levels which suggests a possibility of using these species for bioindication. However, the ratio of metals in V. album to S. aucuparia was different depending on the pollution level.
在这项研究中,我们关注槲寄生及其宿主(花楸树)中的元素浓度,将其作为城市污染的生物标志物。这些分布广泛、在污染地区非常常见的物种,可能为全年监测环境质量提供重要信息,尤其是对槲寄生而言。我们在花楸树的叶片和土壤中以及槲寄生中测量了 Cd、Co、Cr、Cu、Fe、Li、Mg、Mn、Ni、Pb 和 Zn 的浓度,槲寄生是一种半寄生植物,生长在这种树种上。我们在波兰西南部奥洛瓦的城市环境中研究了树木和半寄生植物。选择这个地区是因为锌冶炼厂对土壤和植物金属污染水平的影响,以及比较花楸树和槲寄生积累金属的能力。在奥洛瓦污染程度较低的地区,槲寄生对 Cd、Ni、Pb 和 Zn 的生物积累能力强于 Co,而花楸树对 Co 的生物积累能力则较弱。在污染程度较高的地区,花楸树对 Cd、Ni、Pb 和 Zn 的生物积累能力强于 Co,而槲寄生对 Co 的生物积累能力则较弱。对植物中 Cd、Co、Cr、Cu、Fe、Li、Mg、Mn、Ni、Pb 和 Zn 浓度的聚类分析区分了污染程度较低和较高的地区,这表明可以使用这些物种进行生物指示。然而,槲寄生中金属与花楸树的比例取决于污染水平。
