Abstract
Some procedures, based on analytical and biological methods, are useful tools for risk assessment of treatment plant wastewater. In fact, urban effluents, called “complex mixtures” due to their nature, origin and toxicologic and environmental variability, need a more realistic evaluation. In this study, 11 municipal wastewater effluents were studied. Chemical analysis (GC/MS) and biological methods (acute and chronic toxicity bioassays and estrogenicity, mutagenity and teratogeny tests) were carried out to identify the most frequent organic compounds and toxic effluents. Results showed 7 effluents with acute toxicity, 3 with chronic toxicity and 4, with estrogenic effects. When toxicity and analytical results were compared, it was observed that in effluents with estrogenic effects, at least 3 estrogenic substances were identified. Attending all these results, the inclusion of combined methodologies must be considered to get more realistic information about these situations.The articles published in this journal are subject to the following terms and conditions:
