The West Anatolian Region is one of the most important areas for industrialization, population density and traffic in Turkey. Therefore, the leaves of Populus nigra L. (Salicaceae), which are used as biomonitor to investigate the levels of the trace elements Cd, Pb, Fe, Zn and Cu, were sampled at 30 locations having different pollution levels in the region. The concentrations of elements were determined by atomic absorption spectrometry. The samples were collected at both reference and contaminated locations where iron was found as the priority element. The strong association between a gradient of contamination and concentration in all samples tested indicates that they are reflecting well the environmental changes, and that they appear as appropriate biological indicators of heavy metal contamination.
安纳托利亚西部地区是土耳其工业化、人口密度和交通最为重要的地区之一。因此，作为生物监测器用于调查镉、铅、铁、锌和铜等微量元素水平的黑杨（杨柳科）叶片，在该地区30个污染程度不同的地点进行了采样。通过原子吸收光谱法测定元素浓度。样本在对照点和污染点均有采集，其中铁被视为首要元素。在所有测试样本中，污染梯度与元素浓度之间的强关联表明，它们能很好地反映环境变化，并且是合适的重金属污染生物指标。
