Key research themes
1. How do particulate matter levels and urban factors contribute to air pollution severity and public health impacts in megacities?
This research area focuses on quantifying the concentrations of particulate matter, particularly PM2.5 and PM10, in densely populated urban areas and examines their health and economic consequences. It investigates how factors such as population density, vehicle emissions, topography, meteorological conditions, and urbanization trends exacerbate air pollution, especially in megacities. Understanding these elements is essential for developing targeted interventions to mitigate pollution-related health burdens and economic costs.
Key finding: This study measured ambient PM10 levels in Tehran reaching 77 µg/m3 and PM2.5 concentrations at 32 µg/m3, exceeding WHO guidelines by approximately 3-4 times, attributing pollution severity to vehicular emissions, temperature... Read more
Key finding: This work highlighted the pivotal role of fine particulate matter (PM10 and smaller) from combustion processes, including fossil fuel burning and industrial sources, in causing significant health damage due to deep lung... Read more
Key finding: Through long-term air quality monitoring, this paper statistically analyzed total suspended particulate (TSP) concentrations and other pollutants, identifying lognormal distribution patterns and temporal trends. The approach... Read more
Key finding: This comprehensive analysis categorized primary and secondary pollutants, including particulate matter and volatile organic compounds, detailing their urban sources such as vehicular exhaust and industrial combustion. It... Read more
2. What are the socio-economic and health impacts of air pollution and which interventions show promise in mitigating these effects?
This theme investigates the broad range of detrimental consequences air pollution imposes on human health—ranging from respiratory and cardiovascular diseases to developmental issues—and on socio-economic factors including healthcare costs, productivity loss, and housing markets. It also reviews intervention frameworks, policies, and technological approaches designed to reduce pollution exposure and improve air quality outcomes, providing a foundation for evidence-based policymaking and public health strategies.
Key finding: The survey quantified severe health outcomes such as COPD, lung cancer, stroke, and respiratory infections attributable to particulate matter exposure, accounting for millions of premature deaths globally. It additionally... Read more
Key finding: This research confirmed that prenatal and early childhood exposure to particulate matter significantly impairs fetal growth, increases infant mortality, and leads to respiratory morbidities such as asthma. It emphasized the... Read more
Key finding: The paper detailed multiple pollution types affecting human and ecosystem health and identified major pollution sources from anthropogenic activities. It emphasized the interrelations among air pollution and other... Read more
3. How do atmospheric pollutants contribute to climate change and what global responses exist to mitigate these impacts?
This theme explores the role of greenhouse gases, especially carbon dioxide, methane, and chlorofluorocarbons, emitted largely from fossil fuel combustion and industrial activities, in intensifying the greenhouse effect and driving climate change. It covers emission trends, major contributors, and international frameworks aimed at stabilizing atmospheric greenhouse concentrations to prevent dangerous anthropogenic interference with the climate system.
Key finding: This paper detailed global carbon dioxide emissions, attributing 84% to industrial activity, with the US as the largest emitter followed by China and others. It discussed the implications of increased greenhouse gases for... Read more
Key finding: Providing a comprehensive classification of air pollutants including greenhouse gases, this paper outlined their sources, chemical nature, and meteorological influences on dispersion and transformation. It linked increased... Read more
Key finding: The study traced the historical evolution of air pollution, highlighting the transition from visible smoke emissions to invisible chemical pollutants including greenhouse gases. It emphasized fossil fuel combustion as the... Read more
