The role of the biopolymer polyhydroxybutyrate (PHB, <250 µm) as a vehicle synthetic musks mixture (celestolide, galaxolide, tonalide, musk xylene, moskene and ketone) to Mytilus galloprovincialis was investigated. For 30 days, virgin PHB, PHB+musks (6.82 µg g-1) weathered PHB+musks, were daily spiked into tanks containing mussels, followed by 10-day depuration period. Water tissues samples collected measure exposure concentrations accumulation in tissues. Mussels able actively filter microplastics suspension but concentration found tonalide) markedly lower than concentration. Estimated Trophic Transfer Factors suggest that PHB will only play minor on marine even if our results slightly extended persistence loaded PHB.
