The Olmaliq industrial area in Uzbekistan is believed to represent a risk to the environment and to human health due to the dispersal of contaminants into the air and soil. This study was undertaken to delineate the track of airborne contaminants’ migration and to assess the distribution of such particles deposited on Populus nigra L. cv Italica leaves and soils. Particles were identified using scanning electron microscopy–energy-dispersive X-ray spectroscopy (SEM-EDX), while bulk soil composition was quantified by applying inductively coupled plasma mass spectrometry (ICP-MS). The results of this study confirmed the research hypothesis, indicating the industrial center as a source of pollution and human exposure to metallic contaminants. The Olmaliq area in particular is strongly influenced by atmospheric pollutants from local industries. The spread of ultra-fine particles is mainly governed by the industrial output and the direction of prevailing winds.

黑杨Italica叶作为矿物学和地球化学解释无机大气气溶胶成因的重要工具

据信，由于污染物扩散到空气和土壤中，乌兹别克斯坦的Olmaliq工业区对环境和人类健康构成威胁。进行这项研究是为了确定空气中污染物迁移的轨迹，并评估沉积在黑杨（Populus nigra L. cv Italica）上的此类颗粒的分布。叶子和土壤。使用扫描电子显微镜–能量色散X射线光谱仪（SEM-EDX）识别颗粒，同时通过应用电感耦合等离子体质谱仪（ICP-MS）定量分析大块土壤成分。这项研究的结果证实了研究假说，表明工业中心是污染的源头，也是人类接触金属污染物的源头。尤其是Olmaliq地区，受到当地工业的大气污染物的强烈影响。超细颗粒的扩散主要受工业产量和盛行风的方向控制。
