The term Blue Carbon (BC) was first coined a decade ago to describe the disproportionately large contribution of coastal vegetated ecosystems to global carbon sequestration. The role of BC in climate change mitigation and adaptation has now reached international prominence. To help prioritise future research, we assembled leading experts in the field to agree upon the top-ten pending questions in BC science. Understanding how climate change affects carbon accumulation in mature BC ecosystems and during their restoration was a high priority. Controversial questions included the role of carbonate and macroalgae in BC cycling, and the degree to which greenhouse gases are released following disturbance of BC ecosystems. Scientists seek improved precision of the extent of BC ecosystems; techniques to determine BC provenance; understanding of the factors that influence sequestration in BC ecosystems, with the corresponding value of BC; and the management actions that are effective in enhancing this value. Overall this overview provides a comprehensive road map for the coming decades on future research in BC science.

An electrochemical aptasensor has been developed specifically for the sensitive and selective determination of ochratoxin A (OTA), one of the most important mycotoxins. The aptasensor utilizes a glassy carbon electrode that has been modified with toluidine blue (TB) encapsulated in a Zn-based metal-organic framework (TB@Zn-MOF). The results demonstrate that in the presence of OTA, the peak current of the differential pulse voltammogram (DPV) related to TB oxidation is notably decreased.

Peroxyacetic acid (PAA), as an oxidizing agent, has gained significant attention in the field of advanced oxidation because of its low toxicity and high degradation capacity. In this study, cobalt-iron-based Prussian blue analogs (Co-PBAs) were utilized for the first time to activate PAA for tetracycline degradation. In the Co-PBAs/PAA system, organic radicals (RO•) and high-valent metal oxides are mainly produced.

Offshore aquaculture is undergoing rapid promotion and development in China. However, the potential impacts of offshore aquaculture activities on the marine environment remain insufficiently assessed, which could affect its sustainable development. This study investigated sediments at distances of 0 m (station A), 200 m (station B), 500 m (station C), 1000 m (station D) and 2000 m (station E) from the first submersible cage, "Deep Blue 1", in the Yellow Sea Cold Water Mass.

Food safety issues have become increasingly severe, while the global population continues to grow. Shellfish and algae (SA), as sustainable and environmentally friendly foods, have great significance in helping countries worldwide achieve the goal of carbon neutrality. However, there is still a gap in quantitatively evaluating the carbon neutrality of SA farming.

Developing highly efficient bimetallic metal-organic frameworks (MOFs) as catalysts for Fenton-like reactions holds significant promise for decontamination processes. Although MOFs with excellent decontamination capabilities are achievable, ensuring their long-term stability, especially in the organoarsenic harmless treatment, remains a formidable challenge. Herein, we proposed a unique nanoconfinement strategy using graphene oxide (GO)-supported Prussian blue analogs (PBA) as catalytic membrane, which modulated the peroxymonosulfate (PMS) activation in p-arsanilic acid (p-ASA) degradation from traditional radical pathways to a synergy of both radical and non-radical pathways.
