Quantifying the vector effects of polyethylene microplastics on the accumulation of anthracene to Japanese medaka (Oryzias latipes).

To better assess the risk of microplastics (MPs) as a vector for contaminants, it is essential to understand the relative importance of MPs compared to other pathways for chemical transfer as well as the consequences of co-exposure. In this study, we exposed Japanese medaka (Oryzias latipes) to anthracene (ANT, 0.1 mg/L) in the presence or absence of pristine polyethylene MPs (PE-MPs, 10 beads/L), to quantify the vector effect of PE-MPs on ANT accumulation.
