Toxicity of fresh and aged anthropogenic smoke particles emitted from different burning conditions

Published by U.S. EPA Office of Research and Development (ORD) | U.S. Environmental Protection Agency | Metadata Last Checked: September 18, 2025 | Last Modified: 2023-03-23
This dataset provides information on how photochemical aging alters the chemical compositions of the smoke depending on burning conditions and increases oxygenated VOC emissions but degrades particle-bound PAHs. Also the findings indicate that PAH degradation is more pronounced in flaming than smoldering smoke particles, suggesting that PAH-induced toxicity of the smoke particles varies depending on photochemical aging and burning conditions. This dataset is associated with the following publication: Kim, Y.H., A. Sinha, I. George, D. DeMarini, A. Grieshop, and M. Gilmour. Toxicity of fresh and aged anthropogenic smoke particles emitted from different burning conditions. SCIENCE OF THE TOTAL ENVIRONMENT. Elsevier BV, AMSTERDAM, NETHERLANDS, 892: 164778, (2023).
