英文摘要: The effects of dissolved oxygen and nutrient loading on the concentrations and species of phosphorus at the sediment–water interface were evaluated under laboratory conditions. The results showed that the redox potential was significantly correlated with the total phosphorus, total dissolved phosphorus, total nitrogen, ammonium and nitrate nitrogen levels in an aerobic setting, but no significant correlations were observed under anaerobic conditions. The dynamic equilibrium between the overlying water and sediment tended to balance out over time, and the concentration gradient reduced, when the nutrient loading was changed. The greatest variation was observed in the level of iron/aluminum-bound phosphorus, while the calcium-bound phosphorus and organic phosphorus contents showed relatively minor changes. This study not only illustrates the phosphorus transfer mechanism between sediment and water, but can also contribute to the management and protection of Bohai Bay. © 2018 Elsevier Ltd Citation statistics:
