Modeling of particulate matter dispersion from a cement plant: Upwind-downwind case study

摘要: Abstract The main objective of this study was to identify and investigate the atmospheric dispersion fine particles from a cement plant stack in Doroud (Iran). For that, we used SCREEN3 software, developed by Environmental Protection Agency, Gaussian plume model for source. Simulated concentrations ambient air were compared with measured data evaluate performance both models. Upwind-downwind method also applied ground-level PM10, PM2.5 PM1.0 industry surroundings. maximum particle obtained within radius 1600–1800 m around source downwind direction. Within area modelled strongly correlated in-situ (r2 = 0.98). simulated results show that PM10 have significantly exceeded daily (50 μg/m3, about 62.8%) annual (20 μg/m3, 82.3%) limit values established World Health Organization. Therefore, due hazardous emissions distance greater than 7500 m, direction prevailing wind, is recommended build residents’ habitation. Quantification pollution impacts on public health has increasingly become critical component policy discussion. Both models provide useful information define areas environmental impact assessment recommendations implementation effective local policies mitigation strategies pollution.
