摘要
The contamination of sediments is a hot topic from traditional to emergent pollutants. Although there are numerous related reports, they focus on pollutants rather than sediments themselves. Ignoring the effects of sediments leads to the difficulty in comparison of different researches. To close the research gap, two typical sediments (surface natural water source and artificial water source) are proposed as model sediments in the present work, and polycyclic musks as targeted emerging pollutants were studied. The occurrence and sorption kinetics of polycyclic musks in the two sediments and pore water are significantly different. The essential reasons, revealed by scanning electron microscopy and fourier transform infrared spectroscopy, are the physicochemical properties of sediments. This work initiatively proposes two natural model sediments in the fate of organic pollutants. In order to close the research gaps between special sediment research and general sediment research, the model sediments are recommended to be applied in the future.
