This study is the initial air quality modeling application to investigate the atmospheric dispersion of particulate matter (PM₁₀) released from an industrial plant in a mid-sized city in the northwestern region of Turkey. The study aims to determine how an industrial application might affect air pollution levels in the urban area of that city. Different types of PM₁₀ emission sources at the plant were analyzed to determine their contribution to the overall PM₁₀ level. The main concern of the study was to define whether the PM₁₀ emission from the plant produced any air quality effects on the nearby hospital and downtown area. According to the modeling result, the maximum daily PM₁₀ concentration was observed mostly in the southern part of the plant. The highest daily downwind PM₁₀ was estimated to be 286.3 μg m⁻³, while the annual mean of downwind PM₁₀ concentration was estimated to be 72.6 μg m⁻³. It was found that the highest PM₁₀ was emitted from the line source (282.2 μg m⁻³)—located at the south and southwest of the plant—that has been continuously used for hauling raw materials to the cement plant. In this study, the hauling roads (as a line source) were the hot-spot at the plant and needed serious maintenance for the reduction of PM₁₀ emissions from the plant. In the study area, a sensitive community state facility was subject to be considered an environmental concern since the central hospital complex was located nearby the PM₁₀ source. For this purpose, the American Meteorological Society/Environmental Protection Agency Regulatory Model (AERMOD) was followed to determine whether the plant caused any severe PM₁₀ effect on the central hospital. The results indicate that the maximum hourly PM₁₀ concentrations were predicted as 20 μg m⁻³ for the central hospital area. Overall, the modeled PM₁₀ concentrations from the source at different time scales and locations did not exceed the national air quality limits in the area.

颗粒物（PM10）对空气质量的影响来自工业来源。

这项研究是空气质量建模的初始应用程序，用于研究从土耳其西北地区中型城市的一家工厂排放的颗粒物（PM ₁₀）在大气中的扩散。该研究旨在确定工业应用如何影响该城市市区的空气污染水平。分析了工厂中不同类型的PM ₁₀排放源，以确定它们对总PM ₁₀水平的贡献。该研究的主要关注点是确定该工厂的PM ₁₀排放是否对附近的医院和市区产生了空气质量影响。根据建模结果，每天最大PM ₁₀在植物的南部大部分观察到浓度。最高的顺风PM ₁₀每日估计为286.3μgm ^-3，而顺风PM ₁₀浓度的年平均估计为72.6μgm ^-3。发现最高的PM ₁₀从位于工厂的南部和西南部的线源（282.2μgm ^-3）发出，该线源一直用于将原料拖运到水泥厂。在本研究中，运输道路（作为线源）是工厂的热点，需要认真维护以减少PM ₁₀工厂的排放。在研究区域中，由于中央医院大楼位于PM ₁₀排放源附近，因此敏感的社区州设施被视为环境问题。为此，遵循了美国气象学会/环境保护局的监管模型（AERMOD），以确定该工厂是否对中心医院造成了严重的PM ₁₀危害。结果表明，中心医院区域的每小时最大PM ₁₀浓度预计为20μgm ^-3。总体而言，在不同的时间尺度和位置，从源头模拟的PM ₁₀浓度未超过该地区的国家空气质量限值。
