Abstract

Sulfamethoxazole (SMX) is extensively used antibiotic and residue of SMX has been found in surface and drinking water in ng/L concentration. The advance oxidation process such as ozonation has been proposed for removal of SMX into its possible readily biodegradable intermediates and also limits its impact on the environment. About 20 g/h of ozone dosage used for treatment of sulfamethoxazole (four different concentrations of SMX 10 ppm, 20 ppm, 30 ppm and 40 ppm) resulted in 99 % removal within 60 minutes of ozonation with the leftover of its degradation products. However, the toxicity of degradation products of SMX formed after ozone treatment on soil microorganism (Pseudomonas aeruginosa and Enterobacter xiangfangensis) has not been reported. In the current study toxicity of degradation products using MTT assay has been reported. The study revealed that degradation product of SMX not showing any significant cytotoxic effect on the soil micro-organism compared to pure SMX.
