A growing concern
is being raised for the possibility of these polymers to adsorb
environmental pollutants, and our results clearly confirmed such
hypothesis. Using environmentally realistic levels of dissolved
pyrene, the concentrations on exposed microplastics markedly
increased with a time- and dose-dependent trend. Worthy to note,
the comparison of various experimental conditions did not reveal a
linear relationship with levels of pyrene dosed in seawater, since
the greatest adsorption efficiency was obtained for the medium
treatment (5 mg/L)
