Persistence of the Fluoroquinolone Antibiotic Difloxacin in Soil and Lacking Effects on Nitrogen Turnover.

The article presents a study which examines the association on environmental risks because of using fluoroquinolone antibiotics in animal husbandry and human therapeutics. Difloxacin was administered to pigs and used the contaminated manure to soil, and examined the sequestration and dissipation of difloxacin in soil in the presence and absence of plants. The effect of antibiotic on nitrogen turnover in soil (potential denitrification and nitrification) is also examined. The study shows that difloxacin was very persistent and hardly (bio) accessible under all conditions studied.
