The study explores the uptake of spherical, negatively charged polystyrene nano- and microparticles by plant roots. The researchers used fluorescently labelled polystyrene spheres and two plant species, Arabidopsis and wheat, and investigated their uptake using laser scanning confocal microscopy and pyrolysis gas chromatography-mass spectrometry. The results revealed no active uptake of nano- and microsized polystyrene spheres during plant growth up to the 1- to 2-leaf growth stage. However, pyrolysis GC-MS was unsuccessful due to the presence of natural styrene monomers in the roots and insufficient detection limits. Both 40 nm and 1 μm polystyrene spheres were accumulated at the root surface of each species, particularly at the root tip, but no plastic particles were found in the internal root structure.
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[…]
