Arsenic and heavy metal pollution in wetland soils from tidal freshwater and salt marshes before and after the flow-sediment regulation regime in the Yellow River Delta, China
TLDR
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.About:

Heavy metal fractions and ecological risk assessment in sediments from urban, rural and reclamation-affected rivers of the Pearl River Estuary, China
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.

Sources identification and pollution evaluation of heavy metals in the surface sediments of Bortala River, Northwest China.
TL;DR: The Bortala River is a typical inland river located in an oasis of arid area in northwestern China and can be a reference for the heavy metals pollution prevention, the harmony development of the ecology protection and the economy development ofthe oases of inland river basin of China, Central Asia and also other parts of the world.

Heavy metals in wetland soils along a wetland-forming chronosequence in the Yellow River Delta of China: Levels, sources and toxic risks
TL;DR: In this article, a new and sensitive toxic risk index (TRI) is developed for the accurate assessment of toxic risk for heavy metals in wetland soils compared with the sum of the toxic units (∑TUs), and As, Cr, Ni and Cd showed higher contributions to TRI.

Houjie Wang,Xiao Wu,Naishuang Bi,Song Li,Ping Yuan,Aimei Wang,James P. M. Syvitski,Yoshiki Saito,Yoshiki Saito,Zuosheng Yang,Sumei Liu,Jeffrey A. Nittrouer +11 more
TL;DR: The water-sediment regulation scheme (WSRS) is an unprecedented engineering effort to manage the Yellow River with the aims to mitigate the siltation both in the lower river channel and within the Xiaolangdi Reservoir utilizing the dam-regulated flood water.

World-Wide Delivery of River Sediment to the Oceans
John D. Milliman,Robert H. Meade +1 more
TL;DR: The authors showed that rivers with large sediment loads (annual discharges greater than about $15 \times 10^{6}$ tons) contribute about $7 −times 10 −9$ tons of suspended sediment to the ocean yearly.

TL;DR: Reconstructed time lines, causes, and consequences of change in 12 once diverse and productive estuaries and coastal seas worldwide show similar patterns: Human impacts have depleted >90% of formerly important species, destroyed >65% of seagrass and wetland habitat, degraded water quality, and accelerated species invasions.
