Interactions of N-Sulfadiazine and Soil Components As Evidenced by N-CPMAS NMR.

The extensive use of sulfonamides (SNs) in animal husbandry has led to an unintentional widespread occurrence in several environmental compartments. The implementation of regulations and management recommendations to reduce the potential risk of development of antibiotic resistances necessitates detailed knowledge on their fate in soil. We present results from two independent incubation studies of N-labeled sulfadiazines (SDZ) which focused on identifying binding types in bound residues.
