Sediment quality risk assessment in Liaohe River basin

Qin Yanwen,Han Chaonan,Zheng Binghui,Zhang Lei,Cao Wei

Strategic Study of CAE 2013, Volume 15, Issue 3,   Pages 19-25

Abstract:

56 surface sediment samples were collected from Hunhe River, Taizi RiverBased on heavy metal acute and chronic aquatic toxicity, three grades sediment quality standards forheavy metal in Liaohe River basin were set and sediment pollution index (SPI) that a new assessing methodand end of Dahuofang Reservoir were middle risk which meant that benthic survived in such heavy metal pollutionsediment would suffer slight chronic toxicity effect of heavy metal.

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 6, doi: 10.1007/s11783-016-0886-2

Abstract: The inhibition of sediment nitrogen (N) and phosphorus (P) release seems necessary.Red soil (RS) was firstly used as sediment capping material under flow conditions.RS capping can effectively reduce the N and P release from sediment.Nitrogen (N) and phosphorus (P) released from the sediment to the surface water is a major source ofTherefore, inhibiting sediment nutrient release seems necessary.
