Fishing nets (FNs) represent a significant source of plastic waste, but their contribution to pollution by micro- and nanoplastics (MNPs) associated additives is poorly understood. We studied the degradation high-performance-polyethylene-polypropylene (HPPE-PP) trawl net two trammel made polyamide 6 (PA6) or biodegradable polybutylene-succinate-polybutyrate-adipate-terephthalate (PBS-PBAT). Accelerated artificial ageing (AA) was performed using UV irradiation under environmental extreme conditions followed abrasion in water with glass microbeads. FN organic compound release were as well toxicity leachates on marine bacteria Allivibrio fischeri larvae fish Oryzias latipes. AA FNs caused slight polymer did not produce MNPs. However, conditions, PA6 PBS-PBAT produced 9.1 × 104 MP/mL 2.0 MP/mL, respectively. released total 27 compounds from which 7 quantified at concentrations between 0.35 µg/L (Phthalimide) 200 (Succinic-acid 2-methylallyl-undecyl-ester). Only induced bacteria, bioluminescence inhibition ranging 26 % 56 %. Exposure disrupted behavior. highest behavior stress indicator day 12 (8.5), 25 (8) HPPE-PP (7). concluded that related more than MPs. The bio-based should be further evaluated before wider implementation fishing sector.

This study focuses on the deposition of microplastics (MPs) urban beaches along central São Paulo coastline, utilizing advanced methodologies such as remote sensing, GNSS altimetric surveys, µ-Raman spectroscopy, and machine learning (ML) models. MP concentrations ranged from 6 to 35 MPs/m2, with highest densities observed near Port Santos, attributed industrial port activities. The predominant types identified were foams (48.7%), fragments (27.7%), pellets (23.2%), while fibers rare (0.4%). Beach slope orientation found facilitate concentration deposition, particularly for pellets. study’s ML models showed high predictive accuracy, Random Forest Gradient Boosting performing exceptionally well specific categories (pellet, fragment, fiber, foam, film). Polymer characterization revealed prevalence polyethylene, polypropylene, polystyrene, reflecting sources disposable packaging raw materials. findings emphasize need improved waste management targeted beach cleanups, which currently fail address smaller MPs effectively. research highlights critical role combining in situ data understand dynamics coastal environments. It provides actionable insights mitigation strategies contributes global efforts aligned Sustainable Development Goals, SDG 14, aimed at conserving marine ecosystems reducing pollution.

Microplastics have become prominent environmental pollutants in both marine and freshwater systems, which raises ecological health concerns. This study provides a comprehensive meta-analysis of microplastic concentration data from over 60 studies across Europe, investigating factors influencing distribution. The investigated influences include sampling latitude, proximity to wastewater treatment plants, population density the area, mesh size, distance coastlines, seasonal variations, wind speeds. results indicate that concentrations correlate with size but not environments, suggesting predominant type fresh waters be primary microplastics. Although it is generally accepted, waste water plants contribute pollution, this identifies other more significant factors, such as surface runoff atmospheric deposition. Population shows modest influence, while site coastlines is, contrary findings publications, significantly related levels. Seasonal speed effects are complex, varied impacts locations used correction critically reevaluated. analysis underscores need for standardized methodologies research, recommends specific practices enhance comparability studies, contributes accurate assessment pollution aquatic environments.

The characterization of microplastic (MP) contamination in marine species is increasing as concerns about environmental and food safety are more discussed. Here, we reported a quantitative qualitative assessment the by anthropogenic particles (from visual sorting; AP) MP (plastic-made) whole soft body or digestive tract species. Four commercial were studied, namely Pacific oyster (Magallana gigas), spiny spider crab (Maja sp.), common sole (Solea solea) seabass (Dicentrarchus labrax punctatus). AP uptake studied over three to four seasons depending on After tissues digestion, extracted under stereomicroscope morphometric characteristics reported. Then, polymers identified ATR-FTIR spectroscopy. Seasonal variations mainly described was lower autumn higher spring. These may be linked reproduction growth cycles this Moreover, ingestion compared winter. Contamination crabs soles showed either weak no seasonal trends, both quantitatively qualitatively. Overall, all ranged from 1.17 ± 1.89 AP.ind
