Microplastics are practically ubiquitous contaminants in all environments on the planet. Therefore, present work aimed to investigate microplastic contamination lettuce, chives, and cilantro sold Itacoatiara, Central Amazon, Brazil. Samples of each vegetable were acquired from different commercial establishments. The samples washed with filtered distilled water remove any particles surface vegetables. Hydrogen peroxide was added used wash vegetables digest organic materials. solution stirred daily kept an oven at 60°C. separated using density difference technique. In total, 247 recorded. There no significant number per sample three types size also did not differ significantly between vegetables, smallest (0.067 mm) largest (4.865 being found lettuce. proportion colors recorded varied significantly. Blue red predominant, a greater abundance blue (n=207; 83.8%). particle formats, fibers (n=235; 95.1%) more representative than fragments (n=12; 4.9%). Thus, it can be confirmed that Amazon contaminated, consequently unsafe for direct human consumption, require washing plenty running eliminate before consumed fresh.

Variability in microplastic abundance, bisphenol A contamination, antioxidant properties, and health risks associated with vegetable consumption

Beni-Suef University Journal of Basic and Applied Sciences, Journal Year: 2025, Volume and Issue: 14(1)

Published: April 18, 2025

Abstract Background Plastic pollution, particularly microplastics (MPs) and toxic additives such as bisphenol A (BPA), endangers human health. Therefore, their routes in the environment need to be investigated. This study investigated microplastic abundance, (BPA) levels, antioxidant activity (AA) three commonly consumed vegetables—green amaranth, jute mallow, spinach sourced from two markets Osogbo, southwestern Nigeria. Microscopic technique was used determine MP shapes, colours. High-performance Liquid Chromatography (HPLC) analyse BPA contents while 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay measure AA. hazard index (HI) estimated dietary intakes (EDIs) were estimate associated risks food safety concerns with vegetables. Results In this study, abundance shoots ranged 4.00 ± 0.50 7.67 1.04 particles/g roots 5.33 1.53 18.00 6.93 green respectively, indicating subsoil contamination. Three shapes (fragment, fibre, irregular) five colours (transparent, white, yellow, black, brown) detected, fragment shape transparent colour dominating. Fourier Transform Infrared spectroscopic (FTIR) analysis revealed a predominance of polyethylene, polypropylene, polyethylene terephthalate, polyvinyl chloride, polyamide microplastics. The 5.55 0.56 6.65 0.00 μg/g AA 40.67 6.79 72.55 4.03%. regression principal component (PCA) identify relationship among factors (MPs, BPA, AA). It is suggested that high levels MPs negatively impacted vegetable quality they are environmental Contrastingly, had significant positive correlation quality. Both EDIs HI < 1, no risk exposure consumption. Conclusion highlights potential health contamination intake suggest immediate risks, but long-term remains concern. vegetables warrant stricter monitoring agricultural soil irrigation water sources. Microplastic crops can reduced policies regulate plastic waste disposal promote sustainable farming practices.

Microplastics’ Impact on the Environment and the Challenging Selection of Reliable Key Biomonitors

Water, Journal Year: 2024, Volume and Issue: 16(18), P. 2637 - 2637

Published: Sept. 17, 2024

Microplastics (MPs) persist for long periods in the environment, causing adverse effects on aquatic and terrestrial ecosystems. The accumulation of MPs various trophic levels mostly depends weathering phenomena, their reduced dimensions improved bioavailability; this ultimately causes ingestion by organisms living different niches. modern concern about toxicity collides with current unavailability standardized reliable methodologies to assess risks associated exposure from habitats. Hence, identification selection appropriate biomonitors pollution risk assessment should focus easy-to-implement assays, rapidly interpretable results (e.g., based bioaccumulation capabilities tissues) standardizable methodologies. present review analyzed some emerging exploited evaluation, selected examined according potential use as specific biological indicators diverse environments. research was focused plants, models airborne microfibers evaluation; mussels, key establishment marine environments; land snails, representing studies MPs’ impact soil. Furthermore, recent findings evidenced influence microplastics composition environmental microbiota, enhancing pathogenic biofilms formation, leading increased water, soil, food, crops waste contamination. Disposing harmonized validated methods study integrated promising machine learning tools, might sensibly support management strategies protecting human animal health.

Despite numerous studies assessing the effects of microplastics (MPs) on soils and plants their potential implications for human consumption agriculture, there remains a lack exploration role vegetated ecosystems as natural filters MPs pollution. The stemming from anthropogenic continental activities may undergo retention within these ecosystems, preventing dispersion into aquatic environments. However, questions are raised about impact plant health soil quality. This review aims to address gaps by examining analyzing in retention, sources contaminants soils, absorption/translocation direct physiology growth. Finally, future perspectives knowledge crucial research areas were explored. main findings demonstrate that effectively play retaining MPs, with mainly focused wetlands halophytes, could affect various properties, including bulk density, water microbiota, inducing oxidative stress disturbing persist, such quantifying settings investigating complex relationship between plants, ecosystems. Experiments often employed high concentrations potentially deviating environmental levels thus requiring assessment whether observed can elicit comparable effects. Additionally, predominant focus primary experiments overlooked other types derived degradation larger plastic items, warranting attention inclusion efforts. In conclusion, naturally filter land-based before they reach Nevertheless, particles exhibit significant impacts properties growth, posing an emerging threat terrestrial requires further study.

Here we investigate the suitability of Robinia pseudoacacia L. (black locust) leaflets as a novel biomonitor airborne microplastics (MPs) including tyre wear particles (TWPs). Leaflets were collected from rural roadside locations (ROs, n = 5) and urban parks (UPs, in Siena, Italy. MPs removed by washing, identified stereomicroscope, analysed for polymer type Fourier transform infrared spectroscopy. Daily MP deposition was estimated leaf area. The mass magnetic susceptibility bioaccumulation traffic-related potentially toxic elements (PTEs) also analysed. total number at ROs significantly higher 2962, dominated TWPs, compared with 193 UPs, where TWPs not found. In contrast, microfibres UPs (185 vs. 86). to range 4.2 5.1 MPs/m2/d across 29.9–457.6 ROs. types rubber (80%) followed 15% polyamide (PA) 5% polysulfone (PES), while proportion PES (44%) than PA (22%) polyacrylonitrile (11%). mean susceptibility, proxy metallic particles, (0.62 ± 0.01 10–8 m3/kg) (–0.50 0.03 m3/kg). content PTEs similar sites, except concentrations Sb, tracer vehicle brake wear, (0.308 0.008 µg/g) (0.054 0.006 µg/g).
