Metals' Adsorption Onto Environmental Microplastics at Shoreline Sediments

X-Ray Spectrometry, EarlyView.
ABSTRACT This study assessed trace element concentrations and microplastic (MP) contamination in three sandy beaches on the southern coast of Ilha Grande (Rio de Janeiro, Brazil). Environmental MPs were manually extracted from sand samples, and beaches were classified using the microplastic pollution index (MPPI).
