Microplastics (MPs) have a tremendous potential to sorb hydrophobic organic contaminants in the soil environment. The effects of MPs in the soil systems, however, remain largely unexplored. The objective of this study was to investigate the impact of polyethylene and polystyrene MPs on the transport of the benzo[a]anthracene (BaA) and benzo[a]pyrene (BaP) in soil matrices. In this study, we investigated the sorption process of BaA and BaP in batch sorption experiments in a laboratory and...
