[Display omitted] •Microplastics (MPs) released more Cr in the in-vitro digestive model than in fresh water.•Gastric phase aroused the most bioaccessible Cr(VI) and Cr(III).•Cr on degradable MP was more bioaccessible than Cr on nondegradable MPs.•The Cr exposure via MP consumption was estimated for...
