Discovery and quantification of plastic particle pollution in human blood

Environment International, Journal Year: 2022, Volume and Issue: 163, P. 107199 - 107199

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.

Emergence of Nanoplastic in the Environment and Possible Impact on Human Health

Environmental Science & Technology, Journal Year: 2019, Volume and Issue: 53(4), P. 1748 - 1765

On account of environmental concerns, the fate and adverse effects plastics have attracted considerable interest in past few years. Recent studies indicated potential for fragmentation plastic materials into nanoparticles, i.e., "nanoplastics," their possible accumulation environment. Nanoparticles can show markedly different chemical physical properties than bulk material form. Therefore risks hazards to environment need be considered addressed. However, effect nanoplastics (aquatic) has so far been little explored. In this review, we aim provide an overview literature on emerging topic, with emphasis reported impacts human health, including challenges involved detecting a biological We first discuss sources fates then describe entry routes these particles body, as well uptake mechanisms at cellular level. Since humans not yet extensively studied, focus demonstrating cell responses induced by polystyrene nanoparticles. particular, influence particle size surface chemistry are discussed, order understand recommendations future studies.

Impact of Microplastics and Nanoplastics on Human Health

Nanomaterials, Journal Year: 2021, Volume and Issue: 11(2), P. 496 - 496

Published: Feb. 16, 2021

Plastics have enormous impacts to every aspect of daily life including technology, medicine and treatments, domestic appliances. Most the used plastics are thrown away by consumers after a single use, which has become huge environmental problem as they will end up in landfill, oceans other waterways. These discarded vast numbers each day, breaking down from micro- nano-sizes led worries about how toxic these environment humans. While, there several earlier studies reported effects nano-plastics on environment, is scant research into their impact human body at subcellular or molecular levels. In particular, potential move through gut, lungs skin epithelia causing systemic exposure not been examined thoroughly. This review explores thoroughly nanoplastics created, behave/breakdown within levels toxicity pollution nanoplastics, possible health humans, well suggestions for additional research. paper aims inspire future core elements nano-plastics, biological reactions caused specific unusual qualities.

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.
