MODELING TRANSPORT OF SULFATHIAZOLE IN THREE LOAMY SOILS
Abstract
Veterinary antibiotics are routinely used in livestock operation to combat infectious diseases, to promote growth and to enhance the feed efficiency. However, because the animals often do not completely metabolize the antibiotics, antibiotics consequently are excreted into the environment in partially- or un-metabolized form. This has led to the occurrence of antibiotics in aquatic and terrestrial environment. The mobility of a sulfonamide – sulfathiazole (STZ) – was investigated in three loamy soils – loamy sand, sandy loam, and loam. A series of column studies were performed in an instantaneous pulse mode to closely simulate the land application of manure from livestock operation. Results indicate that the STZ is mobile in all three soils investigated with the mobility being highly dependant on soil water pH. Specifically, increased mobility of STZ was observed at high pH, while significant retardation observed at lower pH. Breakthrough curves for the antibiotics were modeled using the modified one dimensional advection dispersion equation (ADE). The speciation of sulfonamide antibiotics with pH was incorporated into the model by using weighted retardation factor.
