TL;DR: Results showed that most heavy metals in ditch and riparian wetlands did not significantly differ from those in reclaiming wetlands in A region, while significantly lower for Cd, Cu, Pb, and Zn in reclaimed wetlands in B region, suggesting higher effects of long-term reclamation.

TL;DR: Wang et al. as discussed by the authors collected surface sediment (0-15 cm) samples from 31 different grid points throughout the Yilong Lake in April 2004 to study spatial distribution characteristics based on Kriging method and assess their ecological risks posed by these heavy metals.

TL;DR: The redundancy analysis (RDA) revealed that both urbanization and reclamation processes would cause similar metallic characteristics, and sediment organic matter (SOC) might be the prominent influencing factor.

TL;DR: The results demonstrated that marsh soils in both marshes had higher silt and total P contents, higher bulk density and lower sand contents after the flow-sediment regulation; moreover, soil salinity was significantly decreased in the tidal salt marsh As and Cd concentrations were significantly higher in both marsh soils after the regulation than before, and there were no significant differences in the concentrations of Cu, Pb and Zn measured before and after the regulations as discussed by the authors.

TL;DR: The potential ecological risk indices of rural river sediment in this study were equal to those of urban river sediments, implying that the ecological health issues of the rivers in the undeveloped rural area should also be addressed.
