The anaerobic biodegradability and inhibition potential of ozonation products of four biorefractory aromatic compounds (o-cresol, benzenesulfonic acid, 2,5-dichlorophenol and 2,4-dinitrophenol) were evaluated in this study. The ozonation products of all four compounds tested were biodegradable to methane and the biodegradability improved with increasing dose of ozone. Early ozonation products of o-cresol and benzenesulfonic acid were more inhibitory than the initial compounds while ozonation reduced the toxicity of 2,5-dichlorophenol and 2,4-dinitrophenol. Ozonation products formed in the basic pH range were more biodegradable and were less inhibitory than those formed in the acid pH range under the same dose of ozone.
