Abstract [en]

The effect of sulphonamides on activity of activated sludge dehydrogenase was studied. Three sulphonamides, such as sulphacetamide (SCM), sulphanilamide (SA), p-toluenesulphonamide(p-TSA), were selected for investigations and their concentrations ranged from 10 to100 mg/l. Dehydrogenase activity was evaluated with the TTC test. Twelve samples of activated sludge collected from the Gdansk wastewater treatment plant were used. Dehydrogenase activity, its inhibition and degree of toxicity at the presence of sulphonamides have been studied and evaluated. It has been found that the dehydrogenase activity decreases with the increase of a sulphonamidesconcentration, and the effect was the highest for p-TSA. On the other side, the maximal toxicityvalue was the highest in case of SA and the lowest for p-TSA.
