TiO2 nanoparticles in sediments: Effect on the bioavailability of heavy metals in the freshwater bivalve Corbicula fluminea

Most studies investigating the influence of TiO2 NPs on heavy metal bioavailability have focused on the aqueous phase; however, few have examined the sediments containing more nanoparticles. Here, we investigated the effects of TiO2 NPs on heavy metal bioavailability in C. fluminea in sediments. The interactions between the TiO2 NPs and metals in sediments, the influence of TiO2 NPs on metals levels in aqueous phase and geochemical speciation...
