A review of airborne micro- and nano-plastics: Sampling methods, analytical techniques, and exposure risks

Environmental Pollution, Journal Year: 2024, Volume and Issue: 363, P. 125074 - 125074

Published: Oct. 4, 2024

Atmospheric Micro- and nano-plastics (MNPs) can be easily inhaled ingested by humans have become a global health concern. With the development of instruments techniques, an increasing number sampling analytical methods been applied to study airborne MNPs. Active samplers passive collectors are used collect suspended aerosols atmospheric depositions. Microscopes scanning electron microscopy (SEM) physically identify MNPs, while Fourier transform infrared (FTIR), Raman spectroscopy, Pyrolysis gas chromatography-mass spectrometry (Py-GC/MS) polymer compositions However, diversity strategies has greatly limited our ability compare results assess exposure risks. In this review, we extracted data from PubMed, Embase, Scopus 2018 2024 that reported methods, abundance/deposition Through systematic review included 140 articles, emphasized advantages limitations different for collecting analyzing addition, provided in-depth analysis performance specific across environments. Furthermore, current knowledge regarding abundance, deposition, risks risk assessment models discussed. Finally, provide concrete recommendations standardization methods. This identified gaps recommended future research directions

Nanoplastics Detected in Commercial Sea Salt

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(21), P. 9091 - 9101

Published: May 6, 2024

People of all ages consume salt every day, but is it really just salt? Plastic nanoparticles [nanoplastics (NPs)] pose an increasing environmental threat and have begun to contaminate everyday in consumer goods. Herein, we developed a combined surface enhanced Raman scattering (SERS) stimulated (SRS) approach that can realize the filtration, enrichment, detection NPs commercial salt. The Au-loaded (50 nm) anodic alumina oxide substrate was used as SERS explore potential types NP contaminants salts. SRS conduct imaging quantify presence NPs. successfully established through standard plastics, were identified match hydrocarbon group nanoparticles. Simultaneously, quantified based on high spatial resolution rapid platform. sea salts produced Asia, Australasia, Europe, Atlantic studied. We estimate that, depending location, average person could be ingesting many 6 million per year consumption alone. health hazards associated with ingestion should not underestimated.

Underestimated activity-based microplastic intake under scenario-specific exposures

Environmental Science and Ecotechnology, Journal Year: 2023, Volume and Issue: 18, P. 100316 - 100316

Published: Sept. 15, 2023

Despite increasing alarms over the health impacts of microplastics (MPs) due to their detection in human organs and feces, precise exposure evaluations remain scarce. To comprehend risks, there is a distinct need prioritize quantitive estimates MP exposome, particularly at environmentally-realistic level. Here we used method rooted real-world measurements activity patterns determine daily intake MPs through inhalation from ground dust/soil ingestion. We found that nearly 80% this comes residential sectors, with intensity behavioral types significantly affecting burden. The data showed peak for those aged 18-64. When compared dietary sources like seafood, salt, water, identified previously underestimated ingestion, emphasizing more realistic incorporate factors. This discovery raises questions about accuracy past studies underscores MP's potential risks. Moreover, our time-based simulations revealed increased during COVID-19 lockdown surface dust shedding light on how global crises may inadvertently elevate

The number of studies dealing with airborne microplastics (MPs) is increasing but sampling and sample treatment are not standardized, yet. Here, a fast reliable method to characterize MPs presented. It involves the study two passive devices collect atmospheric bulk deposition (wet dry deposition) three digestion methods (two alkaline-oxidative an oxidative) treat samples. based on KOH NaClO was selected for mild organic matrix digestion. In addition, some operational parameters high-throughput quantum cascade laser-based infrared device (LDIR) were optimized: effective automatic tiered approach differentiate fibres from particles (>90 % success in validation) criterion establish positive matches when comparing unknown spectrum against spectral database (proposed match index > 0.85). procedural analytical recoveries very good (82–90 %) slightly lower (62–73 %). Finally, amount type deposited at sub-urban area NW Spain evaluated. Most common polymers Polyethylene (PE), Polypropylene (PP) terephthalate (PET). rates ranged 98–1220 MP/m2/day, ca. 1.7 total collected particles. More than 50 20–50 μm size range, whereas mostly 50–500 range.
