Solute displacement experiments with the antibiotic sulfadiazine (SDZ) and its main transformation products in were performed to investigate the influence of manure on SDZ transport. Either pig manure sulfadiazine (4-amino-N-2-pyrimidinyl-benzenesulfonamide), and its main transformation products C-14-4-OH-SDZ C-14-N-Ac-SDZ, or a C-14-SDZ solution was incorporated in the first centimeter of undisturbed and repacked which were then irrigated. Breakthrough curves (BTCs) of C-14, SDZ, 4-OH-SDZ, N-Ac-SDZ and 4-[2-iminopyrimidine -1(2H)-yl]-anilin were measured. The C-14 distributions vs. depths were determined after the conclusion of experiments. An application of SDZ together with manure resulted in lower peak values of the C-14 BTCs slightly lower amount of eluted mass. In the experiments with manure, the C-14 concentrations in the of the soil columns were higher, probably due to the filtration of manure particles onto which SDZ or its transformation products were sorbed. The transformation products showed a relatively high leaching potential similar Cotransport with organic particles seemed to be of minor relevance for the eluted amounts of solutes. All modeled using a numerical model that considered degradation chains from N-Ac-SDZ into SDZ and from SDZ OH-SDZ, as well as one reversible and one irreversible kinetic sorption site for each solute. The applied model fitted the BTCs of SDZ and its transformation products reasonably well. The fitting process revealed a high mobility of and its transformation products. While N-Ac-SDZ degradation into SDZ was fast and no extended tailing of N-Ac-SDZ was observed, the transport behavior of 4-OH-SDZ was similar to that of SDZ. |
