Despite the numerous studies that have investigated occurrence and fate of plastic particles in environment, only a limited effort has been devoted toward exploring characteristics dissolved organic matter (DOM) leached from microplastics. In this study, using excitation emission matrix-parallel factor analysis (EEM-PARAFAC), we explored fluorescence signatures plastic-derived DOM commonly used materials, which included two polymers (polyvinyl chloride (PVC) polystyrene (PS)), additives...
Municipal wastewater treatment plants (WWTPs) in Korea collect and treat not only domestic wastewater, but also discharge from industrial complexes. However, some discharges contain a large amount of non-biodegradable organic matter, which cannot be treated properly conventional biological WWTP. This study aimed to investigate the characteristics biodegradability matter contained examine fate In contrast most previous studies targeting specific group compounds or traditional water quality...
Abstract Little is known about the production of fluorescent dissolved organic matter (FDOM) in anoxic oceanic sediments. In this study, sediment pore waters were sampled from four different sites Chukchi-East Siberian Seas area to examine bulk carbon (DOC) and their optical properties. The FDOM, coupled with increase nutrients, was observed above sulfate-methane-transition-zone (SMTZ). presence FDOM concurrent sulfate reduction increased alkalinity (R 2 > 0.96, p < 0.0001), suggesting...
Abstract Organic matter (OM) and suspended sediment are abundant, interact with each other, in rivers lakes. OM is usually adsorbed by causes either particle stabilization or flocculation. In this study, the composition flocculation potential of river water were regularly measured throughout year 2016. The samples was a liquid chromatography‐organic carbon detection system fluorescence excitation‐emission matrix spectroscopy, standard jar test experiment. Results from analyses tests,...
Biochar-derived dissolved black carbon (DBC) molecules are dependent on the BC formation temperature and affect fate of emerging contaminants in waters, such as polyvinyl chloride microplastic (MPPVC). However, temperature-dependent evolution MPPVC-interaction DBC remain unclear. Herein, we propose a novel DBC-MPPVC interaction mechanism by systematically interpreting heterogeneous correlations, sequential responses, synergistic relationships thousands their linking functional groups....
