Microplastics as Contaminant Vectors: Influencing the Bioaccessibility of Naphthalene from Freshwater
… from freshwater systems to the human gastrointestinal tract (GIT). The focus was on characterizing the sorption mechanisms of naphthalene and its bioaccessibility (i.e., an estimate of the fraction of an ingested dose that becomes soluble in gastro-intestinal fluids). Three types of MPs, …

Physico-chemical Characteristics and Environmental Fate of a Hydrolytically Degradable Cationic Flocculant
… was then subjected to in-vitro gastrointestinal (GI) digestions with simulated MFT (kaolin), a model contaminant (naphthalene), and simulated municipal wastewater (SMW). Modified physiologically based extraction tests (PBETs) were developed to estimate the bioaccessibility of …
