    A preliminary study on humic-like substances in particulate matter in Malaysia influenced by Indonesian peatland fires
    (Elsevier, 2021) Yusuke Fujii; Susumu Tohno; Kazuhiro Ikeda; Mastura Mahmud; Norimichi Takenaka
    In this paper, ambient total suspended particulates (TSP) with a focus on humic-like substances (HULIS) are characterized based on intensive ground-based field samplings collected in Malaysia during non-haze and haze periods caused by peatland fires on the Indonesian island of Sumatra. Furthermore, concentrations of water-soluble organic carbon (WSOC) and carbon content of HULIS (HULIS-C) were determined, and fluorescence spectra of the HULIS samples were recorded by excitation emission matrix (EEM) fluorescence spectroscopy.
