Transboundary haze pollution refers to the air pollution that crosses national borders, primarily caused by the burning of biomass and agricultural practices. It results in significant environmental and health impacts, affecting air quality and visibility in neighboring countries, and often leads to international disputes and calls for cooperative management and policy interventions.

Key research themes

1. How do chemical composition and meteorological conditions drive the formation and evolution of regional transboundary haze episodes?

This research area focuses on elucidating the chemical characteristics of haze aerosol particles (e.g., PM2.5 and PM10), their source contributions (primary vs. secondary), and the meteorological and atmospheric processes (e.g., stagnant weather, synoptic conditions, boundary layer dynamics, and regional transport) that drive haze formation and persistence. Understanding these factors is critical for effective mitigation, as haze events result from complex interactions between emissions, chemistry, and meteorology across national boundaries.

Key finding: Identified enhanced secondary inorganic aerosols (SIA: sulfate, nitrate, ammonium) and water-soluble inorganic ions as major contributors to both PM2.5 and PM10 during haze events in Beijing; found haze aerosols become more... Read more
Key finding: Demonstrated that multiday haze episodes in Seoul, South Korea, arise from a sequential influence of regional transport of sulfate-rich aerosols from sources such as the North China Plain during early haze stages, followed by... Read more
Key finding: Showed via multilevel measurements in central Beijing that haze formation involves decoupled processes between ground level and elevated layers, where the initial growth of newly formed particles occurs regionally, but severe... Read more
Key finding: Found that cold surges trigger haze initiation in Greater Bangkok by altering temperature, humidity and wind speed, while stagnation and temperature inversion under subsequent synoptic patterns enhance aerosol accumulation;... Read more
Key finding: Observed a significant long-term decrease in concentrations of acidifying pollutants (NH3, SO2, HCl, HNO3) and increase in precipitation pH at multiple altitudes on Mt. Oyama over 25 years, associated with reduced acid fog... Read more

2. What are the primary sources, regional transport pathways, and legal/policy challenges in managing transboundary haze pollution in Southeast Asia?

This theme addresses identification of major haze sources (notably biomass and peatland fires), their spatial and temporal emission patterns, the role of atmospheric transport in haze dispersion across international borders, and the socio-political and regulatory frameworks that govern haze mitigation. Insights from emission inventories, remote sensing, air quality monitoring, and legislation review highlight the challenges and opportunities for effective cross-boundary haze control.

Key finding: Analyzed the complexity of regulating haze caused by agricultural land clearing fires in Indonesia with transboundary impacts in Southeast Asia; highlighted difficulties in enforcing the Transboundary Haze Pollution Act... Read more
Key finding: Reviewed that the main haze contributors to Malaysia's air quality are biomass burning activities, deforestation, and peatland fires in Indonesia, exacerbated by seasonal monsoon winds and climate oscillations like ENSO; also... Read more

Key finding: Provided evidence from aerosol trace element and ion measurements that seasonal Arctic haze results from pollutant transport from mid-latitude sources including Siberia, North America, and Europe; demonstrated the annual... Read more

3. What are the acute health impacts and economic costs associated with exposure to transboundary haze pollution in affected populations?

This research area synthesizes epidemiological, toxicological, and health impact studies linking exposure to haze pollution—especially fine particulate matter dominated by biomass burning products and secondary aerosols—with respiratory, cardiovascular, and neurological morbidity and mortality. It also quantifies economic losses in health care and other socioeconomic sectors, providing a crucial empirical basis to motivate policy and public health interventions in haze-affected regions.

Key finding: Reviewed epidemiological evidence associating haze pollution in China with adverse health outcomes including respiratory and cardiovascular diseases, cancers, and increased premature mortality; chronic and acute exposures to... Read more
Key finding: Synthesized regional studies demonstrating consistent associations between transboundary haze episodes and acute increases in respiratory, cardiovascular, psychological, and neurological morbidities and mortalities across... Read more
Key finding: Identified elevated PM2.5 concentrations and toxic heavy metal elements (Cd, Pb, Ni, Cr, Cu, Zn, Mn) during haze episodes exceeding both WHO and Thai standards; enrichment factor analysis pointed to anthropogenic sources... Read more
Key finding: Quantified health impacts of haze episodes in Malaysia including 19% increased respiratory mortality and heightened hospital admissions for respiratory illnesses, attributing impacts mainly to fine particulate matter with... Read more
