Wastewater treatment contributes to environmental sustainable development indicators such as clean water and sanitation, then, is imperative to improve the mechanisms and process of contaminant removals. The sewage and industrial effluents are the major contributors of pollutants in land and water discharges, and are necessary to enrich the available data for having reference parameters for plant designing and optimization. The physical andchemical assays alone could not be considered sufficient to assess properly the plant performance because complex mixtures demand ecological and biological parameters for a holistic evaluation. Hence, the ecotoxicity and the genetic toxicity measurement become an important tool to complement the conventional water quality parameters, but these parameters are not widely reported in the open access literature. Despite of several studies showed ecotoxicity and the genetic toxicity data, these could be considered not sufficient because the resulted information is derived from single compounds. Considering the scarce data mentioned above this article presents data on the genetic an ecological toxicity of an anaerobic effluent post-treated with ozone and ozone/UV generated by Chaparro et al. [1] and Chaparro and Pires [2].
