Occurrence of microplastics and metals in European seabass produced in different aquaculture systems: Implications for human exposure, risk, and food safety

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 929, P. 172535 - 172535

Published: April 18, 2024

Microplastics (MPs) are emerging contaminants of increasing concern as they may cause adverse effects and carry other contaminants, which potentially compromise human health. Despite occurring in aquatic ecosystems worldwide, the knowledge about MP presence different aquaculture systems their potential impact on seafood products is still limited. This study aimed to determine levels MPs water, feed, European seabass (Dicentrarchus labrax) from three relevant estimate exposure metals through consumption. The recirculating system (RAS) had highest occurrence water feed. followed system's with RAS-farmed fish presenting load, both gastrointestinal tract (GIT) muscle, by pond-, cage-farmed fish. MPs' characteristics across samples remained consistent, predominant recovered particles falling within size range. were visually characterized chemically identified micro-Fourier Transform Infrared Spectroscopy (μFTIR). Most these fibres composed man-made cellulose PET. GIT significantly higher than muscle for pond- fish, bioconcentration factors >1 indicated farmed seabass. Metal concentrations below permissible limits, posing low intake risks consumers according available health-based guidance values estimated dietary scenarios.

Behaviour, ecological impacts of microplastics and cadmium on soil systems: A systematic review

Environmental Technology & Innovation, Journal Year: 2024, Volume and Issue: 35, P. 103637 - 103637

Published: April 18, 2024

Owing to their low cost, high plasticity, and corrosion resistance, plastic products are widely used across various industries. However, these can break down into microplastics (MPs) through several processes, including natural weathering, mechanical wear tear, industrial activities, such as fine powder production, other human-induced processes. MPs contaminate the environment pose a significant threat human health safety. Additionally, be horizontally vertically distributed within soil environment. interact with cadmium (Cd) in Cd-contaminated soils, thereby forming co-exposed stress risks. Considering widespread distribution of Cd soil, this article reviews interactions ecological effects combined literature visualization analysis. The systematic review shows that MP–Cd pollution significantly alter physico-chemical properties thus influencing individual contaminants (Cd or MPs) modifying microbial community. migration contribute oxidative on animals plants, potential implications for aboveground food chain. This paper aims identify future research directions priorities addressing provide scientific guidance remediation management MP-Cd joint exposure site environments.

The use of bidentate ligands for heavy metal removal from contaminated water

Environmental Advances, Journal Year: 2023, Volume and Issue: 15, P. 100460 - 100460

Published: Nov. 27, 2023

Water pollution is responsible for over 1.8 million global death annually. Among the water pollutants are heavy metals including chromium, nickel, copper, arsenic, mercury, and lead. Interestingly, some of cobalt, iron, zinc, manganese components important biological enzymes involved in redox reactions body. However, transitions between various oxidation states these essential sources free radicals leading to oxidative stress. Adsorption has been a well-researched means removing metal pollutants, nevertheless, there problems associated with adsorption processes like generation sludge ballasting, high quantity adsorbent due surface area, toxicity spent adsorbent. Aside from metals, polyaromatic hydrocarbons (PAHs) common originating coal, petroleum, incomplete combustion organic materials. Long exposure several cancers cardiovascular diseases. In this work, utilization bidentate ligands removal contaminated via complexation was examined. Reports have shown that popular adsorbents (biochar, activated carbon, charcoal, cellulose) functionalized provided drastically improved adsorptive capacities. Specifically, such as dithiocarbamate, 5-sulfosalicylic acid, 1,10-phenanthroline removed 99-100% Pb2+ Hg2+ ions. A recent report how inclusion complexes made compounds can remove concert one another.

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.
