Abstract Hydropower dams impact the transport of microplastics from rivers to ocean. The Yangtze River is a large source plastics Here, we report microplastic concentrations and compositions across range size fractions for sediment samples collected in upper lower reaches Three Gorges Dam 2008, 2015, 2019 2020. We find gradual increase abundance over time, with preferential retention small-size...
Polycyclic aromatic hydrocarbon (PAHs) and polychlorinated biphenyls (PCBs) accumulated by semipermeable membrane device (SPMD)-based virtual organisms (VOs) and local feral fish were studied in Three Gorges Reservoir (TGR), China. VOs were deployed at seven sites in TGR for two periods in 2009 and 5 species of fish with different living habitats and feeding habits collected in the same periods...
A new detection device was designed by integrating fiber Bragg grating (FBG) and polyvinyl chloride (PVC) tube in order to monitor the slip surface of a landslide. Using this new FBG-based device, a corresponding slope model with a pre-set slip surface was designed, and seven tests with different soil properties were carried out in laboratory conditions. The FBG sensing fibers were fixed on the...
