As a form of pollution source control and a low-impact development measure, bioretention is a convenient, economical and effective method for the removal of heavy metals from stormwater runoff, which can adapt to the randomness and uncontrollability of non-point source pollution. However, few studies have assessed the performance of bioretention in the simultaneous removal multiple heavy metals and the impact of heavy metal migration on the bioretention life cycle. In this study, the removal rates...

The amount of total suspended solids (TSS) is the most visible indicator for evaluating water quality in reservoirs. Previous investigations paid more attention to TSS of the surface layer in reservoirs, while suspended particles are prone to settle, resuspend, and aggregate at the bottom of reservoir. There may be different patterns of the TSS in different depths. Hence, it is significant to explore the temporal and spatial characteristics of suspended solids in different depths of...
