Published: March 24, 2022

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.

Plasticenta: First evidence of microplastics in human placenta

Environment International, Journal Year: 2020, Volume and Issue: 146, P. 106274 - 106274

Published: Dec. 2, 2020

Microplastics are particles smaller than five millimeters deriving from the degradation of plastic objects present in environment. can move environment to living organisms, including mammals. In this study, six human placentas, collected consenting women with physiological pregnancies, were analyzed by Raman Microspectroscopy evaluate presence microplastics. total, 12 microplastic fragments (ranging 5 10 μm size), spheric or irregular shape found 4 placentas (5 fetal side, maternal side and 3 chorioamniotic membranes); all microplastics characterized terms morphology chemical composition. All them pigmented; three identified as stained polypropylene a thermoplastic polymer, while for other nine it was possible identify only pigments, which used man-made coatings, paints, adhesives, plasters, finger polymers cosmetics personal care products.

Microplastics in freshwaters and drinking water: Critical review and assessment of data quality

Water Research, Journal Year: 2019, Volume and Issue: 155, P. 410 - 422

Published: March 1, 2019

Microplastics have recently been detected in drinking water as well sources. This presence has triggered discussions on possible implications for human health. However, there questions regarding the quality of these occurrence studies since are no standard sampling, extraction and identification methods microplastics. Accordingly, we assessed fifty researching microplastics its major freshwater includes an assessment microplastic data from river lake water, groundwater, tap bottled water. Studies wastewater were also reviewed. We review propose best practices to sample, extract detect provide a quantitative reporting concentrations. Further, summarize findings related concentrations, polymer types particle shapes. frequently present freshwaters number concentrations spanned ten orders magnitude (1 × 10−2 108 #/m3) across individual samples types. only four out 50 received positive scores all proposed criteria, implying is significant need improve assurance sampling analysis samples. The order globally polymers PE ≈ PP > PS PVC PET, which probably reflects global plastic demand higher tendency PET settle result their densities. Fragments, fibres, film, foam pellets most reported conclude that more high needed better understand potential exposure inform health risk assessments.

Plastic Teabags Release Billions of Microparticles and Nanoparticles into Tea

Environmental Science & Technology, Journal Year: 2019, Volume and Issue: 53(21), P. 12300 - 12310

Published: Sept. 25, 2019

The increasing presence of micro- and nano-sized plastics in the environment food chain is growing concern. Although mindful consumers are promoting reduction single-use plastics, some manufacturers creating new plastic packaging to replace traditional paper uses, such as teabags. objective this study was determine whether teabags could release microplastics and/or nanoplastics during a typical steeping process. We show that single teabag at brewing temperature (95 °C) releases approximately 11.6 billion 3.1 into cup beverage. composition released particles matched original (nylon polyethylene terephthalate) using Fourier-transform infrared spectroscopy (FTIR) X-ray photoelectron (XPS). levels nylon terephthalate from several orders magnitude higher than loads previously reported other foods. An initial acute invertebrate toxicity assessment shows exposure only caused dose-dependent behavioral developmental effects.

A Review of Microplastics in Table Salt, Drinking Water, and Air: Direct Human Exposure

Environmental Science & Technology, Journal Year: 2020, Volume and Issue: 54(7), P. 3740 - 3751

Published: March 2, 2020

The ubiquity of microplastics in aquatic and terrestrial environments related ecological impacts have gained global attention. Microplastics been detected table salt, drinking water, air, posing inevitable human exposure risk. However, rigorous analytical methods for detection characterization remain scarce. Knowledge about the potential adverse effects on health via dietary respiratory exposures is also limited. To address these issues, we reviewed 46 publications concerning abundances, sources, air. We summarized probable translocation accumulation pathways within body. Human body burdens through inhalation were estimated to be (0–7.3)×104, (0–4.7)×103, (0–3.0)×107 items per person year, respectively. intake inhalation, especially indoor was much higher than those other routes. Moreover, air impose threats both digestive systems breathing ingestion. Given lifetime microplastics, urgently call a better understanding hazards health.
