en عمومى General مقاله اصیل Original Article <div style="text-align: justify;">Introduction: The intensification of industrial and transportation activities has significantly contributed to air pollution, particularly in cement industrial zones.<br> Methods: This study aimed to model the dispersion of sulfur dioxide (SO2) and carbon monoxide (CO) pollutants around the dedicated port of a cement factory using the AERMOD dispersion model and to assess the associated health risks. A quantitative descriptive approach was employed, involving data collection, field data analysis, and geospatial mapping. The AERMOD software was utilized to simulate the spatial distribution of SO2 and CO emissions, followed by an environmental health risk assessment for the surrounding population.<br> Results: The modeling results showed that the highest concentrations of SO2 and CO reached 196 and 24,407 &mu;g/m&sup3;, respectively. Pollutant dispersion predominantly occurred toward the northeast, influenced by wind patterns and emission source characteristics. Environmental health risk assessment results indicated that long-term exposure to CO&mdash;particularly beyond 15 years&mdash;results in a Risk Quotient (RQ) greater than 1, signifying potential non-carcinogenic health risks. Conversely, SO2 exposure remains below the risk threshold (RQ < 1) for the general population.<br> Conclusion: These findings highlight the urgent need for enhanced emission control measures and focused protection for vulnerable groups. Moreover, they underscore the importance of implementing stricter environmental regulations to mitigate the health impacts of industrial port operations.</div> Environmental pollutants, Air pollution, Cardiovascular system, Respiratory tract disease, Cement plant 1 8 http://ehemj.com/browse.php?a_code=A-10-1-459&slc_lang=en&sid=1 A Muh Cipta Prawira Putra ciptaprawira@gmail.com 100319475328460022544 0009-0003-2834-9802 No Department of Environmental Health, Faculty of Public Health, Hasanuddin University, Makassar, Indonesia Anwar Daud anwardaud66@gmail.com 100319475328460022545 100319475328460022545 No Environmental Studies Center, Hasanuddin University, Makassar, Indonesia Agus Bintara Birawida agusbirawida@gmail.com 100319475328460022546 100319475328460022546 Yes Correspondence to:Department of Environmental Health, Faculty of Public Health, Hasanuddin University, Makassar, Indonesia Anwar Mallongi anwar_envi@yahoo.com 100319475328460022547 100319475328460022547 No Department of Environmental Health, Faculty of Public Health, Hasanuddin University, Makassar, Indonesia Lalu Muhammad Saleh lalums@unhas.ac.id 100319475328460022548 100319475328460022548 No Department of Occupational Health and Safety, Faculty of Public Health, Hasanuddin University, Makassar, Indonesia Muhammad Fahmi Aziz muhammadfahmiaziz@g.ecc.u-tokyo.ac.jp 100319475328460022549 0009-0006-3102-2722 No Department of Human Ecology, School of International Health, The University of Tokyo, Tokyo, Japan
