Nano-/microplastics (NP) are a human-made emerging contaminant with worldwide occurrence. The small size (below one micrometre), the different chemical nature and the persistence make NPs potential hazards with a suspect probability of tissue penetration and inflammation or as accumulators for toxins. A strategy to stop the spill of novel NP is the remediation from wastewater or rivers as prominent distributors. We have developed core–shell superparamagnetic iron oxide nanoparticles (SPIONs) that attract NP and glue them to larger agglomerates, which then can be removed from water by applying an external magnetic field. The shell molecules provide two interaction motifs towards NP. The tuned surface potential of the functionalised SPIONs attracts complementary charged NPs efficiently and the n-alkyl chain is dedicated to preferential interaction towards organic NPs rather than inorganic particles. Structural analytics and molecular dynamics simulation support the proposed concept. Systematic remediation experiments with different NPs (chemical structures, sizes and mixtures) from different waters—including river water—and with different SPION core materials indicate a universal validity of the concept, with the best remediation performance for mixed NPs. We suggest a method for broadband remediation of various NPs with simple materials and processes, which both have the potential to be up-scaled.
The Scheme of Control and Enforcement Scheme (Scheme) of the North East Atlantic Fisheries Commission (NEAFC) applies to all fishing vessels used or intended for use in fishing activities conducted on fisheries resources in the Regulatory Area. The scheme is divided into seven chapters: General Provisions (I), Control Measures (II), Monitoring of Fisheries (III), Vessel[…]
For the purpose of ensuring that fishing activities are in compliance with South Indian Ocean Fisheries Agreement (SIOFA) Conservation and Management Measures (CMMs), this CMM provides regulations that make it easier to monitor, control, and monitor fishing activities. It is the responsibility of the Contracting Parties, cooperating non-contracting party (CNCPs), and participating fishing entities (PFEs) to[…]
In the context of sustainable fishing activities, this Regulation establishes specific rules regarding the eligibility of costs associated with operations that aim to protect and restore marine biodiversity and ecosystems. Additionally, this Regulation addresses the eligibility of costs for operations that aim to mitigate climate change and improve the energy efficiency of fishing vessels. Furthermore,[…]
The Third Caribbean Regional Fisheries Mechanism (CRFM) Strategic Plan (2022-2030) sets out a clear roadmap for achieving the CRFM’s vision of effective management, conservation and sustainable use of our fisheries and aquaculture resources, to maximise social and economic benefits in the CRFM Member States. The plan was approved by the Eleventh Special Meeting of the[…]
This measure is based on the Convention on the Conservation and Management of Fishery Resources in the South East Atlantic Ocean, adopted by the Annual Meeting of the South East Atlantic Fisheries Organization (SEAFO) in 2015, establishes the System of Observation, Inspection, Compliance and Enforcement, which shall apply to all fishing vessels and fishing research[…]
