  • soils
  • Sulfamethazine and erythromycin were degraded in soils, with a larger fraction mineralized in the long-term exposed soil (20 and 65%, respectively) than in control soil (0.4 and 3%, respectively) after 7 days of incubation. (deepdyve.com)
  • Oral
  • 123.8 grains (8.02 grams) Sulfamethazine (Formulated in a sustained release base) are intended for oral administration to ruminating replacement calves (calves over one (1) month old that are not on an all-milk diet). (jefferspet.com)
  • exposure
  • The purpose of the present study was to assess the bioavailability of sulfamethazine, erythromycin, or ciprofloxacin through aqueous extractions with borax or EDTA solutions and their biodegradation following different soil exposure scenarios. (deepdyve.com)
  • Exposure of Fischer 344 rats to sulfamethazine prior to and during gestation did not produce developmental toxicity (embryo/fetotoxicity or teratogenic effect) in their fetuses under the conditions of this study. (nih.gov)
