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.

Mechanism of Nano‐Microplastics Exposure‐Induced Myocardial Fibrosis: DKK3‐Mediated Mitophagy Dysfunction and Pyroptosis

Journal of Biochemical and Molecular Toxicology, Journal Year: 2025, Volume and Issue: 39(5)

Published: April 22, 2025

ABSTRACT Nano‐microplastics (NMPs), as environmental pollutants, are widely present in nature and pose potential threats to biological health. This study aims investigate the mechanisms by which NMPs inhibit mitophagy through suppression of dickkopf‐related protein 3 (DKK3) expression, leading NOD‐like receptor family, pyrin domain containing (NLRP3) inflammasome‐mediated cardiomyocyte pyroptosis promoting myocardial fibrosis. Healthy adult male C57BL/6 mice were administered NMP solution via gavage, their cardiac function was monitored. The results showed that exposure significantly reduced left ventricular ejection fraction (LVEF) fractional shortening (LVFS) increased extent Transcriptome sequencing identified 14 differentially expressed genes (DEGs), including MYL7. Using random forest algorithm functional enrichment analysis, DKK3 a key gene. In Vitro experiments further confirmed downregulate thereby inhibiting pyroptosis. elucidates molecular induce fibrosis provides new theoretical bases targets for diagnosis treatment heart diseases.
