Microplastics in Sediments from a Sandy Beach in Costa Nova (Aveiro, Portugal)

The main objective of this study is to perform an approximation on the microplastic pollution on a sandy beach in Costa Nova (Portugal), focused on longitudinal and cross-sectional transects. The results showed a scarce variability in data, with median concentrations ranging from 142 to 356 p/kg d.w. and 211 to 270 p/kg d.w. in cross-sectional and longitudinal transects, respectively. The predominant morphology was microspheres, which accounted for more than 90% in all samples analysed, whereas the most abundant microplastics were
