The objective of this study was to estimate the health effects attributed PM2.5 exposure in southwest Iran. In order HA-CVD, HA-RD, LC-M, I-As children, RAD, and WDL, exposure-response function method used. annual mean regularly exceeded 5.26-8.5 times from 2021 limit value established by WHO. dominance PM2.5/PM10 ratio decreased -34.6% 2015 2020. results showed that risks HA-CVD (- 51. 9), HA-RD 68.7%), LC-M 43.6%), 52.1%), RAD 56.8%), WDL 58.7%) declined per 105 inhabitants between 2018 2020 . Reducing particulate emissions industries road traffic led lower PM2.5, which will be effective decrease mortality rate.

Assessing the burden of diseases attributed to exposure to ambient particulate matter by air quality modeling

International Journal of Environmental Health Research, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 11

Published: April 29, 2025

This study aimed to assess PM2.5 exposure levels in Ahvaz, Iran, and quantify the associated burden of disease attributable particulate pollution. To uncertainty mortality morbidity, response function model for probabilistic risk assessment was used. The analysis aerosol variations by Aerosol Optical Thickness indicated a decline concentrations during pandemic. During period, annual mean exceeded limit value established World Health Organization. Cause-specific mortality, including trachea bronchus lung cancer, stroke, acute lower respiratory infections, also decreased 14-28% 2020. Restricted activity days work lost 11.8% 13.8%, respectively, correlating with concentrations. Years lived disability dropped from 242.7 170.4 years per 105 capita 2020 Mitigation strategies, green infrastructure, industrial regulation, improved urban planning, are needed reduce health risks this highly polluted region.

Understanding particulate matter emissions from cooking meals, health impacts and policy path in Ecuador

The Science of The Total Environment, Journal Year: 2025, Volume and Issue: 982, P. 179628 - 179628

Published: May 15, 2025

Cooking is a major source of indoor air pollution, but little known about its emissions or health impacts in Ecuadorian households. This study quantified PM₂.₅ and PM₁₀ from six common menus (three fried, three stewed) cooked real-life kitchen Guayaquil lacking natural mechanical ventilation. Each menu was replicated 30 times, yielding 180 PM concentration profiles. After quality control, 120 profiles were retained for analysis. Median 24 h concentrations 16 μg/m3 21 μg/m3, respectively-exceeding WHO 24-hour guidelines % PM₂.₅. Using Disability-Adjusted Life Years (DALYs), the harm exposure estimated at 990 DALYs per 100,000 person-years analyzed cooking scenarios. These levels indicate quantifiable chronic risks despite being lower than other Low Middle Income Countries studies. Findings support need guidelines, ventilation strategies, public policies tailored to urban Latin American
