Description
Summary:The chemical characterization of fine particles from on-road vehicles in the Wutong tunnel in Shenzhen, China was investigated. Elemental carbon and organic matter composed 63% and 34% of the total PM sub(2.5) mass in the Wutong tunnel, respectively. Alkanes, polycyclic aromatic hydrocarbons (PAHs), hopanes, fatty acids, and dicarboxylic acids were the major identified organic compounds, and their source profiles in the PM sub(2.5) in the Wutong tunnel were characterized. The comparisons of measurements with those in the literature were also made to demonstrate the characteristics of the vehicle source profiles in the Wutong tunnel. The experimental results can improve understanding of particulate matter emitted from vehicles in China.
