Effect of aging on the release of di-(2-ethylhexyl) phthalate from biodegradable and petroleum-based microplastics into soil

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 272, P. 116006 - 116006

Due to microplastics (MPs) being widely distributed in soil, the use of advanced oxidation remediate organic-contaminated soils may accelerate aging MPs soil and impact release di-(2-ethylhexyl) phthalate (DEHP), a potential carcinogen used as plasticizer plastics, from MPs. In this study, persulfate (PO) temperature treatment (TT) were treat biodegradable petroleum-based MPs, including polylactic acid (PLA), polyvinyl chloride (PVC), polystyrene (PS). The methods for evaluating characteristics changes MP X-ray diffraction (XRD) analysis water contact angle measurement. effects on DEHP investigated via incubation. results showed PO TT led increased surface roughness, oxygen-containing functional group content, hydrophilicity with prolonged aging, consequently accelerating Interestingly, PLA aged faster than PVC PS under similar conditions. After 30 days treatment, into 0.789-fold, exceeding increase (0.454-fold) (0.287-fold). This suggests that poses higher ecological risk or PS. Furthermore, resulted degradation surface. content PLA, PVC, decreased by 19.1%, 25.8%, 23.5%, respectively. Specifying types studied environmental conditions would provide more precise context results. These findings novel insights fate ecotoxicity arising remediation contaminated soils.

Foodborne and airborne polyethersulfone nanoplastics respectively induce liver and lung injury in mice: Comparison with microplastics

Environment International, Journal Year: 2023, Volume and Issue: 183, P. 108350 - 108350

Published: Nov. 25, 2023

Micro/nanoplastics (MNP) are ubiquitous in the environment and multiple living organisms. The toxicity of some common types MNP, e.g., polyethersulfone (PES) remains poorly understood. Multi-omics approaches were used this study to determine effects foodborne airborne PES MNP on liver lung, respectively. Foodborne capable inducing gut microbial dysbiosis, serum metabolic disruption, transcriptomic dysregulation, affecting antioxidant activity function, resulting injury. As for they found induce nasal lung transcriptome disturbance, cause disrupted NP respectively greater than MP, which could be associated with differences between MP exposures. relevant results suggest that disrupt "gut microbiota-gut-liver" axis hepatic injury, while affect "airborne microbiota-lung" findings benefit diagnoses injury induced by as well proper use human environment.

Microplastic accumulation dynamics and risk assessment in dried fish processed with sea salt at different salting ratios

Journal of Hazardous Materials Advances, Journal Year: 2024, Volume and Issue: 14, P. 100415 - 100415

Published: Feb. 24, 2024

Global food security, particularly in South Asia and low-income coastal regions like India, relies on seafood consumption, both fresh dried. Seafood, encompassing small pelagic fish, dried varieties, salt-cured absorbs xenobiotics micro/nanoplastics their associated contaminants during processing. This occurs due to factors such as processing conditions, the status of fish muscle biochemistry, additives used, presenting largely unexplored health risks that have received minimal study attention. investigates impact salting microplastics (MPs) contamination cured exploring intricate relationship between salting, MPs under controlled conditions. Commercial solar salt used for curing contained an average 40.72 ± 5.97 MPs/g. Microplastic abundance decreased significantly, from 65.7 6 3.36 1.5 items/g, with a lower salt-to-fish ratio 1:10. Characteristics morphotype, size, colour polymer type exhibited similar trends. Protein content showed strong negative correlation, while lipid correlation presence was weak. Various indices factor, load index induced risk emphasized salt's significant role enhancing posing safety consumers. Given limited number studies conducted comprehending uptake processed seafood, critical aspect safety, present aims illuminate interplay biochemistry microplastic characteristics. Additionally, it explores this dynamic, highlighting implications human health.

Identification and Visualization of Polystyrene Microplastics/Nanoplastics in Flavored Yogurt by Raman Imaging

Toxics, Journal Year: 2024, Volume and Issue: 12(5), P. 330 - 330

Published: April 30, 2024

The contamination of food by microplastics has garnered widespread attention, particularly concerning the health risks associated with small-sized microplastics. However, detecting these smaller in poses challenges attributed to complexity matrices and instrumental method limitations. Here, we employed Raman imaging for visualization identification polystyrene particles synthesized polymerization reactions, ranging from 400 2600 nm. We successfully developed a quantitative model particle size concentration polystyrene, exhibiting excellent fit (R2 0.9946). established procedures spiked flavored yogurt using providing fresh insights into microplastic extraction efficiency. Recovery rates calculated models validated method’s feasibility. In practical applications, assessment size, type, shape, quantity unspiked was conducted. most common polymers found were polypropylene, polyethylene, smallest sizes 1 10 μm. Additionally, conducted exposure assessments branded yogurt. This study foundation developing universal quantify food, covering synthesis standards, development, validation, application.
