Outdoor Atmospheric Microplastics within the Humber Region (United Kingdom): Quantification and Chemical Characterisation of Deposited Particles Present
نویسندگان
چکیده
Atmospheric microplastics (MPs) have been consistently captured within air samples on a global scale. Locations with high human activity are reported to MP levels. An urban sampling site in the Humber region (U.K.) has sampled over 13-month period, providing seasonal variation profile of levels, size, shape, and polymer types that humans exposed to. Mean measured using passive fallout into container, were 3055 ± 5072 m−2 day−1 (1164 median). increase levels decrease size was observed, consisting mainly film-shaped MPs (67%) polyethylene (31%) nylon (28%) types. No relationship between rainfall observed. In parallel, five urbanised locations relevant exposure characterised 2-week period. overall mean (and standard deviation) 1500 1279 observed (1012 median), from which petroleum resin accounted for 32% type, higher prevalence industrial roadside zones. These comprised fragment (52%) film (42%) shapes, increased decreasing particle size. The results provide novel information characterising types, can inform cellular toxicity studies, investigating consequences exposure.

BACKGROUND The intimate relationship between dogs and their owners has the potential to increase the risk of human exposure to bacterial pathogens. Over the past 40 years, there have been several reports on transmission of salmonellae from dogs to humans. This study therefore aimed to determine the prevalence of Salmonella in the faeces of dogs from the Midlands region of the United Kingdom to ...
