China Environmental Science, 2017,37(5)1663~1669 Abstract IEPOX-derived organosulfates were observed for the first time in secondary organic aerosols (SOA) at the Tian-jing-shan national air background monitoring station in the Nanling Mountains, South China, during the rainy season in 2015 using a single particle aerosol time-of-flight mass spectrometry (SPAMS). The chemical constituents of fine particles were divided into 9 categories by using the adaptive resonance theory (neural network algorithm, ART-2a): elemental carbon, organic carbon, elemental/organic mixed carbon, levoglucosan, potassium-rich, sodium-rich, silicon-rich, metals and organi
