Dynamics of nitrobenzene degradation and interactions with nitrogen transformations in laboratory-scale constructed wetlands

► Potential application of CWs for NB-containing wastewater treatment was proved. ► NB toxicity produced a negative impact on nitrogen transformations in CWs. ► Positive effect of plants for NB degradation enhancement was demonstrated. ► NB degradation by the release of ammonium with ring cleavage was indicated.
