Abstract

This study investigated the chemical and optical properties of water soluble organic carbon (WSOC) in TSP from urban Seoul in South Korea, including the WSOC concentration, bulk ion composition of water extracts, stable carbon isotope ratio and EEM spectroscopy of WSOC. In general, this paper is well written, however, due to the lack of novelty and other issues listed below, this manuscript is not recommended for acceptance by ACP.
