Transitioning to Microplastic-Free Seed Coatings: Challenges and Solutions

Polymers, Journal Year: 2024, Volume and Issue: 16(14), P. 1969 - 1969

Published: July 10, 2024

This review addresses the issue of replacing manufactured microplastics in seed coatings used agriculture. Firstly, it focuses on policy and regulatory actions taken at a global level. There is no consensus within scientific community definition microplastic and, more generally, classification plastic debris. Nevertheless, several decision schemes have been proposed an attempt to define notion microplastics. The different criteria relevant this definition, such as size, physical state, chemical structure, origin, persistence microplastics, are discussed, with comparison being made between REACH regulation literature. Seed production processing also functions explained order gain better understanding properties be considered substitution strategy for currently main challenges multiple; substitutes must provide same performance microplastics: (i) improving adherence treatment seed, (ii) distributing evenly over (iii) reducing amount dust-off when handling treated (iv) flowability, which particularly important during sowing stage, all while preserving physiological seed. Substitute polymers according desired functional properties: two families biopolymers were identified literature: polysaccharides proteins. Among them, 13 6 polymers, respectively, complied regulation, demonstrating adhesion, dust reduction performances, preservation quality particular. work aims guide future studies coatings, highlight research needs area. It based analysis discussion literature, identifying listing potential substitutes.

Contamination of Thames Estuary sediments by retroreflective glass microbeads, road marking paint fragments and anthropogenic microfibres

The Science of The Total Environment, Journal Year: 2023, Volume and Issue: 912, P. 169257 - 169257

Published: Dec. 19, 2023

Surface and subsurface sediment samples (n = 16) from the highly urbanised inner Thames Estuary (UK) have been physically chemically characterised analysed for anthropogenic microdebris. Sediments were gravelly sands throughout heavily contaminated by lead (Pb, up to 12,500 mg kg−1) zinc (Zn, 9500 kg−1). Microfibres of mm-dimensions retroreflective glass microbeads (median diameter 188 μm) used in road markings most abundant types microdebris present, concentrations (as numbers, N) on a dry weight basis spatially heterogeneous (ranging about 4000 60,000 N kg−1 100 28,000 kg−1, respectively). Nevertheless, two particle significantly correlated both displayed an inverse, non-linear relationship with grain size. Road marking paint fragments different colours detected cases 13) but quantification was difficult because analytical constraints related size, shape, colour, fragmentation encrustation. Concentrations 500 Pb determined isolated particles are unlikely make significant contribution pollution sediments. Overall, our observations suggest that stormwater runoff is source multiple urban estuaries, additional, direct atmospheric deposition contributing microfibre accumulation. More generally, it recommended studies microplastics consider additional debris characteristics better understanding their sources transport.

Airborne microplastics are emerging pollutants originating from disposable tableware, packaging materials, textiles, and other consumer goods. Microplastics vary in shape size exposed to external factors break down into even smaller fractions. abundant both urban natural environments, including water bodies glaciers, as particles can travel long distances. The potential toxicity of airborne cannot be underestimated. Microparticles, especially those < 10 µm, entering the human body through inhalation or ingestion have been shown cause serious adverse health effects, such chronic inflammation, oxidation stress, physical damage tissues, etc. adsorb toxic chemicals biopolymers, forming a polymer corona on their surface, affecting overall toxicity. In addition, also affect carbon dynamics ecosystems impact biochemical cycles. approaches improve sampling techniques develop standardized methods assess still far being perfect. mechanisms microplastic intracellular tissue transport not clear, is understood well. Reduced consumption followed by collection, reuse, recycling contribute solving problem.
