One of the biggest issues in microplastic (MP, plastic items <5 mm) research is lack standardisation and harmonisation all fields, reaching from sampling methodology to sample purification, analytical methods data analysis. This hampers comparability as well reproducibility among studies. Concerning chemical analysis MPs, Fourier-transform infrared (FTIR) spectroscocopy one most powerful tools. Here, focal plane array (FPA) based micro-FTIR (µFTIR) imaging allows for rapid measurement identification without manual preselection putative MP therefore enables large throughputs with high spatial resolution. The resulting huge datasets necessitate automated algorithms a reasonable time frame. Although solutions are available, little known about or level reliability their output. For first time, within our study, we compare two well-established frequently applied regard results abundance, polymer composition size distributions (11-500 µm) derived selected environmental water samples: (a) siMPle tool (systematic MicroPlastics environment) combination MPAPP (MicroPlastic Automated Particle/fibre Pipeline) (b) BPF (Bayreuth Particle Finder). comparison show an overall good accordance but also indicate discrepancies concerning certain types/clusters smallest classes. Our study further demonstrates that detailed essential prerequisite better data.

Plastic particles are ubiquitous pollutants in the living environment and food chain but no study to date has reported on internal exposure of plastic human blood. This study's goal was develop a robust sensitive sampling analytical method with double shot pyrolysis - gas chromatography/mass spectrometry apply it measure ≥700 nm whole blood from 22 healthy volunteers. Four high production volume polymers applied were identified quantified for first time Polyethylene terephthalate, polyethylene styrene (a sum parameter polystyrene, expanded acetonitrile butadiene etc.) most widely encountered, followed by poly(methyl methacrylate). Polypropylene analysed values under limits quantification. In this small set donors, mean quantifiable concentration 1.6 µg/ml, showing measurement mass polymeric component pioneering biomonitoring demonstrated that bioavailable uptake into bloodstream. An understanding these substances humans associated hazard such is needed determine whether or not particle public health risk.

Microplastics and nanoplastics have become emerging particulate anthropogenic pollutants rapidly turned into a field of growing scientific public interest. These tiny plastic particles are found in the environment all around globe as well drinking water food, raising concerns about their impacts on human health. To adequately address these issues, reliable information ambient concentrations microplastics is needed. However, micro- nanoplastic extremely complex diverse terms size, shape, density, polymer type, surface properties, etc. While particle different media can vary by up to 10 orders magnitude, analysis such samples may resemble searching for needle haystack. This highlights critical importance appropriate methods chemical identification, quantification, characterization nanoplastics. The present article reviews advanced representative mass-based particle-based microplastics, with focus sensitivity lower-size limit detection. advantages limitations methods, complementarity comprehensive discussed. A special attention paid approaches Finally, an outlook establishing harmonized standardized analyze challenging contaminants presented, perspectives within beyond this research

Plastics are now omnipresent in our daily lives. The existence of microplastics (1 µm to 5 mm length) and possibly even nanoplastics (<1 μm) has recently raised health concerns. In particular, believed be more toxic since their smaller size renders them much amenable, compared microplastics, enter the human body. However, detecting imposes tremendous analytical challenges on both nano-level sensitivity plastic-identifying specificity, leading a knowledge gap this mysterious nanoworld surrounding us. To address these challenges, we developed hyperspectral stimulated Raman scattering (SRS) imaging platform with an automated plastic identification algorithm that allows micro-nano analysis at single-particle level high chemical specificity throughput. We first validated enhancement narrow band SRS enable high-speed single nanoplastic detection below 100 nm. then devised data-driven spectral matching imposed by sensitive narrow-band achieve robust determination common polymers. With established technique, studied plastics from bottled water as model system. successfully detected identified major types. Micro-nano concentrations were estimated about 2.4 ± 1.3 × 10

In recent years, the presence of microplastics (MPs) and nanoplastics (NPs) has been assessed in several environmental matrices, including marine environment agricultural soil, suggesting those pollutants are likely to enter food web. However, there is still a severe lack information about occurrence plastic particles our food, partially due multidimensionality data necessary fully describe MP contamination consequent difficulty validating analytical methods. this review, consisting two parts, preliminary results MPs water, beverages summarized (Part I) approaches for characterization micro- nano-sized reported discussed II). The gathered manuscript highlights need more comprehensive knowledge MP/NP along chain order assess safety risk related contaminants implement strategies their monitoring products intended human consumption. Therefore, an outlook field towards coherent, consistent, policy-relevant collection standardization included review.

Microplastics (MP) are plastic particles with dimension up to 5 mm. Due their persistence, global spread across different ecosystems and potential human health effects, they have gained increasing attention during the last decade. However, extent of exposure MP through pathways intake not been elucidated.The objective this review is provide an overview on inhalation, ingestion, dermal contact considering data from open bibliography in air, dust, food, water drinks.A bibliographic search Scopus PubMed was conducted using keywords outdoor indoor food including beverages (n = 521). Articles were sorted by title abstract 213), only studies reporting identification quantification techniques further considered 168). A total 115 articles that include quality assurance control (QA/QC) procedures finally discussed present review. Based concentration available literature, we estimated inhaled dose (ID), dust (DI), daily (EDI) via beverages. Finally, (TDI) both inhalation ingestion routes provided for adults, infants newborns.The concentrations according bibliography. Human air food/drinks consumption revealed drinking waters main sources MP.This study reveals humans constantly exposed MP, environment ingest decisively contribute intake. Additionally, highlight newborns high needed evaluate presence risk vulnerable age-population.
