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 have been detected in human stool, lungs, and placentas, which direct exposure to the external environment through various body cavities, including oral/anal cavity uterine/vaginal cavity. Crucial data on microplastic completely enclosed organs are still lacking. Herein, we used a laser infrared chemical imaging system scanning electron microscopy investigate whether microplastics exist heart its surrounding tissues. Microplastic specimens were collected from 15 cardiac surgery patients, 6 pericardia, epicardial adipose tissues, 11 pericardial 3 myocardia, 5 left atrial appendages, 7 pairs of pre- postoperative venous blood samples. not universally present all tissue samples, but nine types found across five with largest measuring 469 μm diameter. Nine also samples maximum diameter 184 μm, type distribution showed alterations following surgical procedure. Moreover, presence poly(methyl methacrylate) appendage, tissue, cannot be attributed accidental during surgery, providing evidence patients undergoing surgery. Further research is needed examine impact introduction potential effects internal health.

In recent years, there has been mounting concern about the bearing of microplastics on human health and comprehensive natural environment. These particles come from a variety sources, such as soaps, personal care products, rundown bigger plastic items. The impacts marine life other ecosystems are substantial, including ingestion by animals, interference with their reproductive systems, even death. economic implications also significant, industries, fishing tourism being affected presence in Exposure to can pose potential risks humans, respiratory digestive problems, well disrupt sleep, contribute obesity, increase risk diabetes. To address this issue, policies initiatives have put place reduce microplastic pollution, but challenges that need be overcome, lack awareness, limited resources, ineffective regulations. Further research is needed fully understand our develop effective strategies mitigate problem. article, we discussed requirement multifaceted approach reducing use, promoting proper disposal recycling waste, developing innovative technologies for capturing removing environment, raising public implementing regulations policies. It only through concerted efforts collaboration between individuals, governments threat tackled.

Rapid single-particle chemical imaging of nanoplastics by SRS microscopy

Proceedings of the National Academy of Sciences, Год журнала: 2024, Номер 121(3)

Опубликована: Янв. 8, 2024

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

Analysis of microplastics in drinking water and other clean water samples with micro-Raman and micro-infrared spectroscopy: minimum requirements and best practice guidelines

Analytical and Bioanalytical Chemistry, Год журнала: 2021, Номер 413(24), С. 5969 - 5994

Abstract Microplastics are a widespread contaminant found not only in various natural habitats but also drinking waters. With spectroscopic methods, the polymer type, number, size, and size distribution as well shape of microplastic particles waters can be determined, which is great relevance to toxicological studies. Methods used studies so far show huge diversity regarding experimental setups often lack certain quality assurance aspects. To overcome these problems, this critical review consensus paper 12 European analytical laboratories institutions, dealing with particle identification quantification gives guidance toward harmonized analysis clean The aims (i) improve reliability analysis, (ii) facilitate planning sample preparation detection, (iii) provide better understanding evaluation already existing aims, we hope make an important step harmonization water samples and, thus, allow comparability results obtained different by using similar or methods. Clean samples, for purpose paper, considered comprise all low matrix content, particular drinking, tap, bottled water, other types such freshwater. Graphical abstract

The prevalence of micro and nanoplastics (MNPs) across the various environments their negative impact on ecosystems have become a serious global threat are currently subject many environmental concerns. Studies provided evidence that MNPs potential to leach toxic plastic chemical additives can adsorb variety persistent organic pollutants, thereby enhancing bioavailability, toxicity, dispersion. Moreover, these easily penetrate food chain might cause health problems when ingested by humans other organisms. Currently, there is complexity in understanding mechanisms which chemicals adsorb/desorb onto/from MNPs, physical biological impacts additives. To date, considerable lack knowledge major concern used industry, fate once dispose into environment, factors affect degradation, consequent human health. This review critically analyzes current concerning physical, chemical, pollutants associated with MNPs. Emphasis was laid types, occurrence, fate, distribution environment. different techniques identification, characterization, removal were also elucidated. Furthermore, harmful effects discussed spur more future studies fill gaps this area.

Combating environmental pollution constantly requires new affinity tools to selectively recognize and sensitively detect them. Molecularly imprinted polymers (MIPs) are plastic antibodies that have exhibited great potential as recognition units in optical sensing platforms monitor wide varieties of pollutants, including ionic species, organic compounds, gases, even manufactured nanoparticles. The construction, strategies, applications molecular-imprinting-based sensors (MI-OSs) been discussed recent reviews, thus we deliberately set them aside. This Perspective elaborates on unanswered questions main approaches being taken address the challenges MI-OS technologies, which less considered until now. Specifically, highlight obscure technical aspects fabrication validation impact their practical importantly offer conceivable solutions related problems bridge research gap.
