Discovery and quantification of plastic particle pollution in human blood

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

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.

Source, migration and toxicology of microplastics in soil

Environment International, Journal Year: 2020, Volume and Issue: 137, P. 105263 - 105263

Published: Feb. 19, 2020

Microplastics are emerging contaminants and their presence in water soil ecosystems has recently drawn considerable attention because they pose a great threat to entire ecosystems. Recent researches have focused on the detection, occurrence, characterization, toxicology of microplastics marine freshwater ecosystems; however, our understanding ecological effects is still limited compared with that aquatic Here, we compiled literature, studying sources, migration soil, negative impacts health function, trophic transfer food chains, corresponding adverse organisms order address potential human risks caused by soil. This review aims gaps knowledge, shed light propose future studies microplastic pollution resultant ecotoxicity. Furthermore, this limiting establishing management remediation measures mitigate posed pollution.

Toxicity of Microplastics and Nanoplastics in Mammalian Systems

International Journal of Environmental Research and Public Health, Journal Year: 2020, Volume and Issue: 17(5), P. 1509 - 1509

Published: Feb. 26, 2020

Fragmented or otherwise miniaturized plastic materials in the form of micro- nanoplastics have been nagging environmental concern. Perturbation organismal physiology and behavior by widely documented for marine invertebrates. Some these effects are also manifested larger vertebrates such as fishes. More recently, possible on mammalian gut microbiota well host cellular metabolic toxicity reported mouse models. Human exposure to occurs largely through ingestion, found food derived from packaging, but a less well-defined manner though inhalation. The pathophysiological consequences acute chronic system, particularly humans, yet unclear. In this review, we focus recent findings related potential detrimental demonstrated models human cell lines. prevailing data suggest that accumulation tissues would likely negative, unclear long-term consequences. There is need systemic due be better illuminated, underlying mechanisms defined further work.

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.
