Outline
The effects of two polarity fractions of pig manure DOM on the transport of doxycycline, enrofloxacin, florfenicol, and sulfamethazine in the surface and subsurface soils of a Lei bamboo forest were examined in this study. The results of batch experiment showed that the addition of the hydrophilic fraction of pig manure DOM significantly reduced the adsorption of doxycycline, enrofloxacin, and florfenicol in the soils, while the addition of the hydrophobic fraction of pig manure DOM significantly enhanced the adsorption of doxycycline and sulfamethazine. It was found that enrofloxacin and doxycycline could not break through any of the tested soil columns. The additions of either polarity fraction of pig manure DOM decreased the breakthrough recovery of florfenicol in surface soil columns by 2.25% and 20.43%, respectively, while the addition of either DOM fraction greatly increased the breakthrough recovery of florfenicol in subsurface soil columns (to nearly 100%). In surface soil columns, the addition of the hydrophilic fraction of pig manure DOM increased the breakthrough recovery of sulfamethazine, while the addition of the hydrophilic fraction of pig manure DOM decreased the breakthrough recovery of sulfamethazine. In subsurface soil columns, the addition of either DOM fractions markedly decreased the breakthrough recovery of sulfamethazine. Irrespective of the addition of hydrophilic/hydrophobic fraction of pig DOM, florfenicol exhibited a higher breakthrough recovery than sulfamethazine, implying that florfenicol has the highest leaching risk.
