Multi-tracer evaluation of cesium-137 bioaccumulation and trophic transfer in marine organisms off Jeju Island, Korea

Radionuclides accidentally released from nuclear facilities into the marine environment may affect ecosystems far from their original sources, yet their ecological behavior in such regions remains poorly understood. Using a multi-tracer approach, we evaluated 137 Cs bioaccumulati...

Integrated Valorization of Macroalgae in a Recyclable Ionic Liquid: Hydrothermal Production of Formic and Levulinic Acids with Product Recovery and Biohydrogen Generation

Abstract Marine macroalgae are drawing growing interest as underutilized feedstocks for chemicals and fuels and as high-productivity, carbon-assimilating biomass that could contribute to carbon capture and sequestration strategies. Here, we investigate an ionic-liquid-assisted hy...
