Anthracene that has been dispersed into atmospheric particulate matter is photooxidized to an array of products reminiscent of oxidation by singlet oxygen in the solution phase. Photooxidation is a more important degradative pathway under ambient conditions than ozonation. Significant disappearance of anthracene also occurs by pathways not involving oxygenation.
