The abstract of an August 15, 2021 Atmospheric Environment paper https://doi.org/10.1016/j.atmosenv.2021.118512 by researchers with the UK University of Hull reports “… Knowledge regarding the presence of suspended microplastics (MPs) within the air is lacking, especially indoors ... This study is the first to report MPs within multiple homes over a 6-month period … Twenty households, within the City of Hull and Humber region, U.K., were passively sampled, each month, collecting atmospheric fallout at head height for subsequent particle quantification, characterisation and μFTIR validation ... Polyethylene terephthalate (PET) was present in 90% of samples and accounted for 62% of MPs. Additionally, polyamide (PA) and polypropylene (PP) were common. Results indicate that humans are exposed to significantly (1–45 times) higher concentrations, and ranges, of MPs within homes compared with the outdoor environment …” #Microplastics #PlasticWaste #SingleUsePlastic @UniOfHull
