Water-sediment interactions and mobility of heavy metals in aquatic environments

• Mineralogy affects adsorption and desorption of heavy metals. Particulate organic carbon enhances metals to riverine sediments. phosphorus estuarine Dissolved increases release in environments. Increasing salinity promotes the water column. The adsorption-desorption behaviour aquatic environments is complex processes are regulated by continuous interactions between This study provides a quantitative understanding effects nutrients key sediment properties on influence levels environmental factors were determined as conditional regression coefficients. research outcomes indicate that mineralogical composition sediments, which other properties, such specific surface area cation exchange capacity, play most important role It was found particulate matter influential nutrient environment, while more under conditions. do not exert significant positive effect area, whilst dissolved transfer from sediments overlying Furthermore, interdependencies marine-related ions an increase mobility result reactions.
