Sediment microbial communities are an important sink for both organic and inorganic nitrogen (N), with microphytobenthos (MPB) biomass having the largest contribution to short-term N-assimilation and retention. Coastal waters are increasingly subject to anthropogenic nutrient enrichment, but the effect of nutrient enrichment on microbial assimilation, processing, and fate of MPB-derived N (MPB-N) remains

The comments (Kopinke, 2020) do not accurately represent the experimental conditions, parameter values, and conceptual model used in our study (Rusevova and Huling, 2020), leading to a misinterpretation of the results. The kinetic analysis used to determine the surface scavenging rate constant (kS) involved competition kinetics between the probe and the mineral surfaces (Rusevova and Huling, 2020);

Magnetite is known to exhibit high catalytic reactivity in Fenton-like reactions merely at low pH conditions. Here we report the association of Cu2+ ion can significantly enhance peroxydisulfate (PDS) activation with magnetite under environmental aquatic conditions (near neutral pH). Cu2+ is able to synergistically activate PDS with magnetite to generate radicals, e.g., SO4·−, at neutral or slightly

Surface water quality management requires foresighted decision making regarding long-term investments. It should consider multiple objectives (e.g. related to different pollutants and costs), integrate multiple sources of pollution (point and diffuse sources), and external conditions that change over time (climate, population and land-use changes). Multi-attribute value theory can support such decisions
