Toxicity and bioaccumulation in benthic organisms
Polychlorinated Biphenyl Release from Resuspended Hudson River Sediment
(American Chemical Society, 2007)
Three shear turbulence resuspension mesocosms (STORM tanks) were used to examine the release of polychlorinated biphenyls (PCBs) from resuspended Hudson River sediment. Twenty-two percent of the resuspended PCBs desorbed ...
The impact of resuspension on sediment mercury dynamics, and methylmercury production and fate: A mesocosm study
The objective of this study was to investigate the effects of resuspension on the fate and bioaccumulation of mercury (THg) and methylmercury (MeHg) in shallow estuarine environments, using mesocosms. Two 4-week experiments ...
Effect of Sediment Manipulation on the Biogeochemistry of Experimental Sediment Systems
(Alliance Communications Group, 2006)
Before biological or biogeochemical experimentation, sediments are often manipulated and defaunated with the use of many different approaches and only modest consideration of treatment effects on sediment biogeochemistry ...
Biofiltration, water quality, and sediment processes
The effect of resuspension on the fate of total mercury and methyl mercury in a shallow estuarine ecosystem: a mesocosm study
Sediments are the major repository of mercury in estuaries and could be a significant source of Hg to the overlying water column via release from the solid phase during resuspension. There is, however, little information ...
Eastern oyster, Crassostrea virginica, valve gape behavior under diel‑cycling hypoxia
Hypoxia and anoxia in many estuaries worldwide can cause a wide range of negative effects on animals that are directly exposed or indirectly influenced by food web interactions. Typically, experimental studies focus on ...
