Microplastics – Detection in Living Human Lungs Reported

The abstract of an article in the July 20, 2022 issue of Science of the Total Environment https://www.sciencedirect.com/science/article/pii/S0048969722020009 by researchers with UK University of Hull and UK Castle Hill Hospital reports that “… This study analysed digested human lung tissue samples … using μFTIR spectroscopy (size limitation of 3 μm) to detect and characterise any Airborne microplastics (MPs) present. In total, 39 MPs were identified within 11 of the 13 lung tissue samples ... Of the MPs detected, 12 polymer types were identified with polypropylene, PP (23%), polyethylene terephthalate, PET (18%) and resin (15%) the most abundant. MPs (unadjusted) were identified within all regions of the lung … The study demonstrates the highest level of contamination control and reports unadjusted values alongside different contamination adjustment techniques. These results support inhalation as a route of exposure for environmental MPs, and this characterisation of types and levels can now inform realistic conditions for laboratory exposure experiments, with the aim of determining health impacts …” #PlasticWaste #SingleUsePlastic #MicroPlastics @UniOfHull
