SEM images and respective EDS spectra with elemental quantitative data of analysed fibres from filtered extracts of pellets of the kingfisher. a Microplastic fibre on silver filter with specific elemental composition and C:O ratio corresponding to PET. b Microplastic fibre on silver filter with specific elemental composition of C = 100% indicating polymeric origin. Gold (Au) was removed from the output listing as it derived from the gold-coating
