Photochemistry complicates attribution of volatile organics

Authors


Abstract

Understanding the sources of air pollution is important in mitigation efforts. Commonly used models known as receptor models often do not take into account chemical reactions that may occur between the source of the emission and the site where measurements are taken. To determine to what extent photochemical reactions in the atmosphere may be affecting source attribution of volatile organic compounds (VOCs), Yuan et al. measured VOCs at an urban site in Beijing in August–September 2010 and identified emission sources.
