Microplastics (MPs) are in all environmental compartments, including atmosphere, terrestrial, and aquatic environments as well marine organisms, foods, drinking water, indoor outdoor environments. MPs can enter the human body through food chain contaminated environment. Ingestion, inhalation, dermal contact routes of their entry into body. Recent studies reporting detection within have raised concern among scientific community knowledge about exposure is still very limited impact on health not well-understood yet. In this review article, we briefly cover reports evidencing MP body, e.g., stool, placenta, lungs, liver, sputum, breast milk, blood. A concise synopsis sample preparation analysis such matrices also provided. This article presents a summary effect cell lines health.

Nanoplastics (<1000 nm) have been evidenced to be universal in a variety of environmental media. They pose potential cytotoxicity and health risk due their tiny size, which allows them easily penetrate biological barriers enter cells. Here, we briefly review the various prevalent analytical techniques or tools for identifying nanoplastics, further move focus on advantages disadvantages. Surface-enhanced Raman spectroscopy (SERS) has implemented identification individual nanoparticles because its high sensitivity molecules ease rapid characterization. Therefore, introduce SERS technique following aspects, (1) principles SERS; (2) strategies advances detection nanoplastics; (3) applying real samples. We put our effort into summarization efficient substrates that essentially enable better extend discuss how reported nanoplastics pretreatment methodologies can bring analysis practical applications. A step moving forward is investigate problems challenges currently applied methods look at future research needs employing analysis.

The micro-, submicron-, and nanoplastic hunt: A review of detection methods for plastic particles

Chemosphere, Год журнала: 2022, Номер 293, С. 133514 - 133514

Опубликована: Янв. 8, 2022

Plastic particle pollution has been shown to be almost completely ubiquitous within our surrounding environment. This ubiquity in combination with a variety of unique properties (e.g. density, hydrophobicity, surface functionalization, shape and size, transition temperatures, mechanical properties) the ever-increasing levels plastic production use begun garner heightened interest scientific community. However, as result these properties, particles are often reported challenging study complex (i.e. real) environments. Therefore, this review aims summarize research generated on multiple facets micro- nanoplastics field; ranging from size definitions detection characterization techniques generating reference particles; order provide more complete understanding current strategies for analysis particles. information is then used generalized recommendations researchers consider they attempt plastics analytically environments; including method validation using obtained via presented creation methods, encouraging efforts towards standardization through reporting all technical details utilized study, providing analytical pathway depending upon exact knowledge desired samples being studied.

Roadmap for optical tweezers

Journal of Physics Photonics, Год журнала: 2023, Номер 5(2), С. 022501 - 022501

Опубликована: Янв. 23, 2023

Abstract Optical tweezers are tools made of light that enable contactless pushing, trapping, and manipulation objects, ranging from atoms to space sails. Since the pioneering work by Arthur Ashkin in 1970s, optical have evolved into sophisticated instruments been employed a broad range applications life sciences, physics, engineering. These include accurate force torque measurement at femtonewton level, microrheology complex fluids, single micro- nano-particle spectroscopy, single-cell analysis, statistical-physics experiments. This roadmap provides insights current investigations involving forces their theoretical foundations designs setups. It also offers perspectives for wide research fields, biophysics exploration.

Assessing the Mass Concentration of Microplastics and Nanoplastics in Wastewater Treatment Plants by Pyrolysis Gas Chromatography–Mass Spectrometry

Environmental Science & Technology, Год журнала: 2023, Номер 57(8), С. 3114 - 3123

Опубликована: Фев. 14, 2023

The level of microplastics (MPs) in wastewater treatment plants (WWTPs) has been well evaluated by the particle number, while mass concentration MPs and especially nanoplastics (NPs) remains unclear. In this study, pyrolysis gas chromatography–mass spectrometry was used to determine concentrations NPs with different size ranges (0.01–1, 1–50, 50–1000 μm) across whole schemes two WWTPs. total decreased from 26.23 11.28 μg/L influent 1.75 0.71 effluent, removal rates 93.3 93.7% A B, respectively. proportions (0.01–1 were 12.0–17.9 5.6–19.5% respectively, efficiency lower than that (>1 μm). Based on annual effluent discharge, it is estimated about 0.321 0.052 tons released into river each year. Overall, study investigated a wide range 0.01–1000 μm wastewater, which provided valuable information regarding pollution distribution characteristics MPs, NPs,

Microplastic sample purification methods - Assessing detrimental effects of purification procedures on specific plastic types

The Science of The Total Environment, Год журнала: 2022, Номер 833, С. 154824 - 154824

Опубликована: Март 26, 2022

In search of effective, fast, and cheap methods to purify environmental samples for microplastic analysis, scientific literature provides various purification protocols. However, while most these protocols effectively the samples, some may also degrade targeted polymers. This study was conducted systematically compare effects based on acidic, alkaline, oxidative, enzymatic digestion extraction via density separation eight relevant plastic types. It offers insights into how specific compromise detection by documenting visible gravimetric effects, analyzing potential surface degradation using Fourier transform infrared spectroscopy (FTIR) bulk erosion a molecular level gel permeation chromatography (GPC). For example, strong acids high temperatures are likely completely dissolve or cause wide range polymers (PA, PC, PET, PS, PUR & PVC), alkaline solutions damage PC PET. Contrarily, Fenton's reagent, multiple steps, as well treatment with zinc chloride solution frequently used density-separation, do not tested here. Therefore, their implementation in sample processing be considered an essential stepping-stone towards standardized protocol future microplastics analyses.

Microplastics (MPs) have been identified as emerging environmental pollutants classified primary or secondary based on their source. Composition, shape, size, and colour, among other characteristics, are associated with capacity to access the food chain risks.
