At high food rations effects were only observed for one of the nano - TiO2 , P - 25 , at high exposure levels ( 10 mg / l ) under both semi - static and particle re - suspension conditions , which suggest that P - 25 effects were mediated by clogging the gut and hence diminishing food acquisition .
