“…This is the first detection since facemasks had never been found in the area before the pandemic. Fourier Transform Infrared Spectroscopy (FTIR) analysis identified the mask as polypropylene, a common material used in disposable facemasks ( Chen et al, 2022 ; Chua et al, 2020 ; Fukuoka et al, 2022 ). Although sea turtles can excrete small amounts of plastic ( Tomas et al, 2002 ), the accumulation of these tiny plastic materials can cause blockage in the digestive tract.…”

“…It was reported that exposure to airborne MPs could cause inflammation, immune disorders, and neurodegeneration ( Prata et al, 2020 ). Moreover, aquatic organisms easily ingest facemasks, affecting the food web that could end up in the human diet ( Aragaw, 2020 ; Bradney et al, 2019 ; Chen et al, 2022 ; Dharmaraj et al, 2021 ; Issac and Kandasubramanian, 2021 ; Ray et al, 2022 ; Zhao et al, 2022 ). It mainly concerns coastal populations, which rely heavily on seafood as their primary protein source ( Bene et al, 2016 ; Mendoza et al, 2021 ; Rodrigues and Villasante, 2016 ).…”

“…Bacterial filtration efficiency (BFE) of PLA-based MBs was evaluated and adapted from the standard YY 0469-2011 "Medical Surgical Mask". 35 Before the test, the sample was placed in an environment with temperature of 22 °C and relative humidity of 27% for pretreatment for 4 h. Bacterial suspension was prepared, and Staphylococcus aureus (ATCC6538) was inoculated into a proper amount of trypsin soybean broth, and cultured at 37 °C for 24 h. Then, the above culture was diluted with 1.5% peptone to a concentration of about 5 × 10 5 CFU mL −1 . The gas flow rate through the sampler was controlled at 28.3 L min −1 , the time of delivering bacterial suspension to the sprayer was set at 1 min, the air pressure and the running time of the sampler were set at 2 min, and the bacterial aerosol was collected on trypsin soybean agar.…”
