Response of sulfate concentration to eutrophication on …
The dramatical increase of sulfur concentration in eutrophic lakes, especially sulfate (SO 4 2−), has brought attention to the impact on the lake ecosystem; however, the mechanisms driving the intensification of eutrophication and the role of SO₄ 2− concentrations remain poorly understood. To assess the impact of eutrophication on SO 4 2− dynamics in lakes, this study monitored …
