The use of biological responses to contaminant exposure by lichen species has become a useful tool in environmental quality evaluation and risk assesment. Lichen Hypogymnia physodes and Usnea hirta samples were collected in 2006 from 10 sites around iron-steel factory in Karabük, Turkey. H. physodes and U. hirta samples from Yenice forest were used as a control. The aim of present study was to evaluate the bioaccumulation ability and to determine the environmental impact of an iron-steel factory in Karabük. Seven elements (Zn, Cu, Mn, Fe, Pb, Ni, Cr and Cd) were analysed by atomic absorption spectrometry (AAS). The analytical results were compared statistically by using SPSS. As expected, the study area (Yenice forest, Karabük) chosen as control site (site no 11) showed significantly lower impact in comparison to other site (site no 1-10). Compared with the two lichen species, H. physodes showed highest metal accumulating capacity while U. hirta showed lowest. These criteria attested the best suitability for H. physodes, followed by U. hirta.
利用地衣物种对污染物暴露的生物反应已成为环境质量评估和风险评估中的一种有用工具。2006年，从土耳其卡拉比克钢铁厂周边的10个地点采集了地衣扁枝衣（Hypogymnia physodes）和长松萝（Usnea hirta）样本。来自耶尼切森林的扁枝衣和长松萝样本用作对照。本研究的目的是评估生物累积能力，并确定卡拉比克一家钢铁厂对环境的影响。采用原子吸收光谱法（AAS）分析了七种元素（锌、铜、锰、铁、铅、镍、铬和镉）。使用SPSS对分析结果进行统计学比较。正如预期的那样，作为对照地点（第11号地点）的研究区域（耶尼切森林，卡拉比克）与其他地点（第1 - 10号地点）相比，影响显著较低。与这两种地衣物种相比，扁枝衣表现出最高的金属积累能力，而长松萝表现出最低的能力。这些标准证明扁枝衣最适合，其次是长松萝。
