[Display omitted] •Accumulation of heavy metals on the MPs fitted to a pseudo first-order kinetics.•Cu, Zn, Cd, and Ni on MPs were primarily distributed in the acid soluble fraction.•Pb and As primarily occur in the reducible fraction.•Mobility and bioavailability of metals on MPs ware higher than t...
