Abstract
Abstract The microscopic interactions between nanoparticles with different physicochemical properties and benzo[a]pyrene (BaP) in environmental waters and human blood are still unknown. By using dissipative particle dynamics method, we found that the interaction parameter between beads in nanoparticles and BaP (aNP) can dictate the dispersion state of them in water and the distance between protein corona and nanoparticles in simulated human blood. Moreover, blood proteins reduce the number of BaP adsorbed on nanoparticles when aNP ≤ 25 and increase the number of BaP when aNP > 25. These findings provide detailed interaction information of combined pollutants at microscopic level.
