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.

Epithelial barrier hypothesis: Effect of the external exposome on the microbiome and epithelial barriers in allergic disease

Allergy, Journal Year: 2022, Volume and Issue: 77(5), P. 1418 - 1449

Published: Feb. 2, 2022

Environmental exposure plays a major role in the development of allergic diseases. The exposome can be classified into internal (e.g., aging, hormones, and metabolic processes), specific external chemical pollutants or lifestyle factors), general broader socioeconomic psychological contexts) domains, all which are interrelated. All factors we exposed to, from moment conception to death, part exposome. Several hundreds thousands new chemicals have been introduced modern life without our having full understanding their toxic health effects ways mitigate these effects. Climate change, air pollution, microplastics, tobacco smoke, changes loss biodiversity, alterations dietary habits, microbiome due modernization, urbanization, globalization constitute surrounding environment Some disrupt epithelial barriers skin mucosal surfaces, disruptions linked last few decades increasing prevalence severity inflammatory diseases such as atopic dermatitis, food allergy, rhinitis, chronic rhinosinusitis, eosinophilic esophagitis, asthma. barrier hypothesis provides mechanistic explanation how explain rapid increase autoimmune In this review, discuss affecting planet's context 'epithelial hypothesis,' including climate emphasize on addition, roles increased fatty acid consumption environmental substances (detergents, airborne pollen, ozone, nanoparticles, tobacco) discussed.

Microplastics in the Environment: Intake through the Food Web, Human Exposure and Toxicological Effects

Toxics, Journal Year: 2021, Volume and Issue: 9(9), P. 224 - 224

Published: Sept. 16, 2021

Recently, studies on microplastics (MPs) have increased rapidly due to the growing awareness of potential health risks related their occurrence. The first part this review is devoted MP occurrence, distribution, and quantification. MPs can be transferred from environment humans mainly through inhalation, secondly ingestion, and, a lesser extent, dermal contact. As regards food web contamination, we discuss microplastic presence not only in most investigated sources, such as seafood, drinking water, salts, but also other foods honey, sugar, milk, fruit, meat (chickens, cows, pigs). All literature data suggest not-negligible human exposure above-mentioned routes. Consequently, several research efforts been assessing risks. Initially, toxicological were conducted with aquatic organisms then experimental mammal animal models cell cultures. In latter case, effects observed at high concentrations (polystyrene common benchmark) for short time. Further must performed assess real consequences contamination low prolonged exposure.

The Minderoo-Monaco Commission on Plastics and Human Health

Plastics have conveyed great benefits to humanity and made possible some of the most significant advances modern civilization in fields as diverse medicine, electronics, aerospace, construction, food packaging, sports. It is now clear, however, that plastics are also responsible for harms human health, economy, earth's environment. These occur at every stage plastic life cycle, from extraction coal, oil, gas its main feedstocks through ultimate disposal into The extent these not been systematically assessed, their magnitude fully quantified, economic costs comprehensively counted.The goals this Minderoo-Monaco Commission on Human Health examine plastics' impacts across cycle on: (1) health well-being; (2) global environment, especially ocean; (3) economy; (4) vulnerable populations-the poor, minorities, world's children.
