The oncology institutions work with medicines of high capacity teratogenic, mutagenic and carcinogenic drugs. Antineoplastic agents are referred to as emerging contaminants, and the disturbing factor is that 10 to 50% of the quantity of chemotherapeutic inserted into the human body passes by the metabolism without changes. The human excretions and disposal incorrect of anticancer drugs are a concern due because the potential risk that characterizes this category of effluent in the environment. In Goiânia, wastewater from oncological institutions do not receive specific treatment, being carried by collector networks to Municipal Sewage Treatment Stations, which has no ability to withdraw these contaminants. Given the above, this study aims to characterize the effluent from two oncology clinics and compare them with a source of domestic wastewater through physical, chemical, microbiological and ecotoxicological properties. The physical, chemical and microbiological characteristics were chosen in order to consider the resolution CONAMA 430/2011, using the methodology proposed by Standard Methods for the Examination of Water and Wastewater, and the Environmental Protection Agency, and ecotoxicological analyzes were made on two test organisms, Ceriodaphnia dubia, second the Norm 13373/2010, for chronic and acute toxicity, and Allium cepa, second Fiskejö (1985) for cytotoxicity and genotoxity. As a result, it was found that the effluent from oncology clinics, although do not present differences in physical, chemical and microbiological tests in front of domestic effluent, showed high toxicity, with 100% mortality in Ceriodaphnia dubia, and aberrations of cytotoxic and genotoxic character in Allium cepa, at concentrations in the range of 6.25% in ecotoxicological tests. This shows the importance of this treatment before reaching the collecting public.
