This research aimed to measure particulate matter concentrations (PM, PM, PM, PM, and total suspended particles) at five locations in Miercurea Ciuc, while also monitoring road traffic intensity and meteorological parameters. Significant differences in particulate matter concentrations were observed across various points in the city. On weekdays, morning aerosol levels were notably higher than those in the afternoon, whereas weekend concentrations were generally lower and more stable throughout the day. Early morning measurements showed a strong correlation with peak traffic periods. During rainy conditions, PM levels returned to baseline values. In the city center, PM concentrations were typically higher (93.16% of the time) than those recorded by the Environmental Protection Agency, averaging 3.27 times greater than at the HR station.
本研究旨在测量米尔库雷亚久克五个地点的颗粒物浓度（PM、PM、PM、PM和总悬浮颗粒物），同时监测道路交通强度和气象参数。在城市的各个地点观察到颗粒物浓度存在显著差异。在工作日，早晨的气溶胶水平明显高于下午，而周末的浓度通常较低且全天更为稳定。清晨测量结果与交通高峰期呈现出很强的相关性。在降雨条件下，PM水平恢复到基线值。在市中心，PM浓度通常更高（93.16%的时间），高于环境保护局记录的浓度，平均比人力资源站高出3.27倍。
