Yes they can theoretically be absorbed but it is in equilibrium so they could also desorb as the concentration in the water changes. The quantities and masses of the plastic particles are so small that it is unlikely that the dosage from absorbed substances would be significant. Depending upon size it would be expected that most of the particles would not go into circulation, so they should be eliminated in feces.
