The pollution with As, Cd, Co, Cr, Cu, Fe, Mn, Pb, Sb and Zn on the territory of Bulgaria has been evaluated using standardized samples of leaves of Populus nigra 'Italica' collected during the last 10 years. Background values for the respective elements are established in the leaves of the plant. The comparisons of urban and industrial pollution to some other European countries indicates similar or lower concentrations. Using cluster analysis of the analytical data the territory of Bulgaria is divided into six regions with different pollution levels.
利用过去10年收集的意大利黑杨树叶标准化样本，对保加利亚境内砷、镉、钴、铬、铜、铁、锰、铅、锑和锌的污染情况进行了评估。确定了植物叶片中各元素的背景值。将保加利亚城市和工业污染与其他一些欧洲国家进行比较，结果表明其污染浓度相似或更低。通过对分析数据进行聚类分析，保加利亚领土被划分为六个污染水平不同的区域。
