Article Synopsis
- The oxidative potential (OP) of particulate matter (PM) significantly impacts health, yet the sources of PM-OP in India are not well understood.
- Research conducted at five sites in the Indo-Gangetic Plain identifies major PM sources and their geographical origins, revealing that high PM levels are widespread but driven by local emissions, particularly in Delhi.
- The study highlights that the main PM sources in Delhi are from traffic exhaust and residential heating, while outside Delhi, biomass burning plays a crucial role, suggesting that improving combustion processes can reduce health risks from PM exposure in northern India.
Air quality is of large concern in the city of Krakow, southern Poland. A comprehensive study was launched by us in which two PM fractions (PM and PM) were sampled during 1-year campaign, lasting from April 21, 2018 to March 19, 2019. A suite of modern analytical methods was used to characterize the chemical composition of the collected samples.

- Aerosols significantly influence the Arctic atmosphere's radiation balance, with organic aerosols being a major component that remains poorly understood.
- Analysis from eight Arctic observatories reveals that winter organic aerosols are primarily from anthropogenic sources in Eurasia, while summer sees a shift to natural emissions like marine and biogenic aerosols.
- The strength and effects of these aerosol sources are influenced by environmental factors like nutrient levels, solar radiation, temperature, and snow cover, providing key insights for climate impact modeling in the Arctic.
