Size-segregated particulate chemical composition in Xinken, Pearl River Delta, China: OC/EC and organic compounds

A total of eight daytime and nighttime size-segregated samples classified into continental and coastal trajectories were analysed for mass concentration, organic and elemental carbon (OC/EC), dicarboxylic acids (DCAs), alkanes and polycyclic aromatic hydrocarbons (PAHs). Comparisons of day- and nighttime as well as continental and coastal samples were carried out for every component in all considered particle size classes. Measured concentrations for all particle components and significant concentration differences for day/night or continental/coastal samples will be discussed in detail and used for a rough source assignment.
