ABSTRACT Synthetic microfibers are emerging environmental microplastic pollutants released from different industrial and domestic sources. The present investigation describes the isolation of potential bacterial strains microplastic‐contaminated sites Bhubaneswar city Odisha, India. Four morphologically distinct were isolated using 2% polyethylene glycol (PEG) supplemented nutrient agar (NA) medium screened for their polymer tolerance ability by growing them on 2%–8% PEG. A single microorganism capable 8% PEG was selected biodegradation experiment. Through 16S rRNA sequencing, strain identified as Exiguobacterium sp. with gene bank accession number ON318396. microbial strain's microfiber assessed in a laboratory setting over period 28 ± 2 days, utilizing optimized conditions an initial pH 7, mL inoculum volume, incubation temperature 30°C 2°C, 150 rpm, g polyester microfiber.

Microfiber prevalence and removal efficiency of textile effluent treatment plants in Bangladesh

Journal of Hazardous Materials Advances, Год журнала: 2024, Номер 14, С. 100436 - 100436

Bangladesh is one of the hubs textile industry in world; consequently, microfibers are an emerging threat to aquatic ecosystem. Traditional effluent treatment plants (ETPs) might not be capable removing most pollutants like surfactants, dyes, and additives, including microfibers, may a major source microfiber pollution through products ETPs. This study investigated eleven woven, knit, denim industries' ETP abundance removal efficiency. The average (range) found influent, effluent, sludge samples was 615.45 ± 377.52 particles/L (170−1,460), 212.72 80.14 (130−380), 10,545.45 7,989.54 particles/kg (4,400−31,000), respectively. abundant shape fiber, microfibres had sizes between 0 100 μm. Eight distinct colors were samples; black color among all samples, followed by brown blue. studied ETPs showed 23.52% 82.19% rate, which satisfactory for minimizing pollution. Fourier transform infrared (FTIR) analysis revealed that main polymers nylon, ethylene-vinyl acetate (EVA), polyethylene terephthalate (PETE), acrylonitrile butadiene styrene (ABS), cellulose (CA), low-density (LDPE or linear LDPE), high-density (HDPE). contamination factor (CF) load index (PLI), assess ecological risks, moderately very highly contaminated could pose findings would help identify transformative challenges required from industrial sectors improving systems.

Microplastics, microfibers and associated microbiota biofilm analysis in seawater, a case study from the Vesuvian Coast, southern Italy

Journal of Hazardous Materials, Год журнала: 2025, Номер 488, С. 137468 - 137468

Опубликована: Фев. 4, 2025

The growing concerns regarding pollution from microplastics (MPs) and microfibers (MFs) have driven the scientific community to develop new solutions for monitoring ecosystems. However, many of proposed technologies still include protocols treating environmental samples that may alter plastic materials, leading inaccurate results both in observation counting. For this reason, we are refining a protocol, based on optical microscopy without use pretreatments, applicable different matrices, which allows not only counting but also complete morphological characterization MPs MFs. Previously, protocol has successfully been tested marine sediments Vesuvian area Gulf Naples (Italy) with good results. In present study, MFs seawater collected same geographical provide comprehensive overview their distribution environments. enabled collection information colonies microorganisms microparticles. Next Generation Sequencing (NGS) metagenomic us characterize microbiota composition sampled MPs, so-called Plastisphere. analytical approach allowed several potentially pathogenic bacteria, represent potential threat environment human health. fact, they exploit ability form biofilms plastics proliferate

Abstract Microplastic (MP) contamination in fish may occur via their feeding behavior and ingestion of contaminated prey. This study investigated the presence MPs predator Lutjanus russellii (Russell’s snapper) its prey along Chumphon coast Central Gulf Thailand. Stomach contents L . were analyzed to identify species. Prey species then sampled from same geographical area as specimens for subsequent MP analysis. The dietary habits classify it a generalist carnivore, consuming diverse range food items, including zooplankton, crustaceans, small fish. No significant correlation was observed between abundance weight or length (general linear model, p > 0.05). Black red fibers predominant types both prey, though sizes varied among In stomachs, most common polymers acrylonitrile butadiene styrene (ABS; 26.32%), polyethylene terephthalate (PET; 21.05%), polyester (PES; 10.53%). Conversely, samples dominated by PES (17.58%), PET (15.38%), ABS (13.19%). Notably, similarities characteristics (shape, color, average size, certain polymer types) Portunus sp. detection smaller compared (Mann–Whitney U -test, ≤ 0.05) suggests transfer through hard-shelled crustacean underscores importance examining predator–prey interactions better understand pathways marine ecosystems, particularly regions like Thailand, where plastic pollution is prevalent. Further research required assess long-term ecological implications within chains.

Urbanization can increase the threat plastic litter poses to beaches around world. However, many oceanic lack baseline data on how urbanization may be altering abundance. Here, I documented abundance and type of at 23 that spanned an gradient (as measured by population density) along California, USA coast in October 2023. Across all sites, found significantly increased for types including (large microplastic 2-5 mm; mesoplastic 5-25 macroplastic >25 mm). also urban had more (132.7 pieces/m2 ± 84.2 S.D.) than non-urban (67.4 30.9 S.D.). In addition, higher abundances cigarette butts, hard plastic, foamed beaches. Collectively, my findings suggest pollution important California beaches, areas impacted this over time, waste from recreation (both off-shore) could source pollution.

Опубликована: Июль 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.
