In this study, we present the results of microscopic observations of pine needles L. collected in the area of cement-lime pressure in the south-western part of the Świętokrzyskie Mountains in the region of Białe Zagłębie. Images of scanning electron microscopy (SEM) confirm the presence of particles with a size of about 2 to 20 µm on the surface of the needles. Analysis using X-ray energy dispersion spectroscopy (EDS) allowed, in turn, to identify lead, iron, aluminium, calcium, and silicon in particles deposited in the surface layer of assimilation organs and dispersed in the surface layer of vegetation tissue within cell structures. Chemical composition, size and shape of particles of foreign bodies on the needles' surface allow them to be identified as cement-lime dust coming from production plants located in the Białe Zagłębie. Negative influence on the condition and liveliness of Scots pine in the study area is manifested by images on which stomata is sealed, which limits the possibility of gas exchange.
在本研究中，我们展示了在比奥莱特扎格列地区的圣十字山脉西南部水泥石灰压力区域采集的松树针叶的微观观察结果。扫描电子显微镜（SEM）图像证实，针叶表面存在尺寸约为2至20微米的颗粒。通过X射线能量色散光谱（EDS）分析，进而确定了沉积在同化器官表层并分散在植被组织表层细胞结构内的颗粒中的铅、铁、铝、钙和硅。针叶表面异物颗粒的化学成分、大小和形状使其被鉴定为来自比奥莱特扎格列地区生产工厂的水泥石灰粉尘。气孔被封闭的图像表明，研究区域内的苏格兰松树的状况和活力受到了负面影响，这限制了气体交换的可能性。
