Article Synopsis
- The study investigated ambient air particles and gases in Kyoto from 2001 to 2004 using various analytical techniques to understand their origins and behaviors.
- The results showed a bimodal size distribution of suspended particulate matter (SPM), primarily consisting of fine particles (< 2.1 microm), with a notable presence of metals like Na, Mg, Al, and others in coarser particles, influenced by shifting weather patterns and the continental “Kosa” phenomenon.
- Seasonal variations affected the concentrations of specific gases and particulate ions, indicating differences in air quality and pollution sources throughout the year, with summer exhibiting higher levels of certain gases compared to winter.
