This study evaluated changes in microplastic (MP) distribution, composition, and ecological risks two coastal harbors Taiwan before during the COVID-19 lockdown. Surface water samples collected at fish revealed that while overall MP concentrations declined most sites lockdown, localized increases were detected, underscoring spatial heterogeneity influence of site-specific factors. Analysis particle characteristics showed a shift toward smaller size fractions (25–50 μm) an ongoing dominance fragments, alongside modest films, fibers, microbeads. Notably, polymer types observed, including marked reduction rayon—likely reflecting decreased human visitation—and increased prevalence polyethylene (PE) linked to packaging delivery services. The emergence polymethyl methacrylate (PMMA) possibly heightened use protective materials, elevated site's risk category. These findings highlight complexity pollution dynamics, demonstrating short-term alterations behavior can reshape assemblages associated risks. Continued monitoring targeted mitigation strategies, particularly periods disrupted socioeconomic activity, are essential for reducing inputs safeguarding marine environments.

Although the ingestion of microplastics by fish has been investigated extensively over last 50 years, quality these studies is questionable due to lack standard methods for sampling, extraction, and identification microplastics. This review aims provide reliable results microplastic occurrence in sourced from 104 published articles through a rigorous assessment data quality. A scoring system was performed assess ten assurance/quality control criteria including sampling methods, sample size, processing storage, laboratory preparation, clean air conditions, negative controls, positive target component, treatment polymer identification. We found that 59 out had scores ≤10, only two are identified with higher than 15, demonstrating urgent need improve reliability digestion studies.

Abstract Plastic pollution is considered a pervasive global environmental challenge. Colored microplastics are prevalent in aquatic environments and the gastrointestinal tracts of wild-captured fish crustaceans. Fish thought to employ color vision detect microplastics, prompting our investigation into microplastic ingestion patterns three marine species, Chrysiptera cyanea , Hypoatherina tsurugae, Plotosus japonicus freshwater Rhodeus ocellatus Pseudorasbora parva Misgurnus anguillicaudatus . Microplastics red, blue, yellow, green, gray were introduced these their was observed over 4 h period under light conditions. Additionally, as crustaceans play an important role connecting producers (phytoplankton) consumers (fish) natural ecosystems, we assessed crustacean, Neocaridina denticulata The crustacean did not ingest only 14% P. individuals ingested (a proportion lower than that other species). Notably, C. R. exhibited preferences ingestion, with favoring preferring blue gray, red yellow. Conversely, H. tsurugae parva, M. exhibit such These findings suggest certain use recognize selectively preference being species-specific. Overall, this study provides new insights by fish, potentially informing future toxicological assessments intendan consumption.

As one of the emerging pollutants, microplastics (MPs) can be taken up by aquatic organisms through ingestion. However, little is known about uptake pattern in over time and associated mechanisms retention patterns. The present study aims to elucidate these patterns fish, their relationship with light/dark conditions, examine kinetic process small-sized plastic especially during long-neglected dark period. Zebrafish were sampled every 2 h light periods after exposure an environmentally relevant concentration (100 items/L) MPs. results demonstrated that MP residues zebrafish decreased period rather than increased time. rhythm swimming behavior exposed displayed a statistically significant variation. Moreover, very strong positive correlation was found between speed number gastrointestinal tracts zebrafish. These clearly demonstrate fibrous fish have discernible diel pattern. This work improves understanding dynamic residual MPs calls for further in-depth circadian toxicokinetic studies better suit particle pollutants.
