Alterações no comportamento das algas euglenas gracilis na presença de 17α etinilestradiol e 17 β estradiol. Braz. J. Aquat. Sci. Technol. 20(2). eISSN 1983-9057. DOI: 10.14210/bjast.v20n2. There is growing concern about contamination of water resources by “emerging pollutants”. Endocrine interferons (EI) from pharmaceuticals, such as 17α-ethynyl estradiol and 17β-estradiol, fit this condition. This problem has been studied by researchers because little is known about the ecotoxicological risk of such compounds. There are several methods that aim to perform biomonitoring for the presence of EIs previously mentioned, such as tests involving yeast or genetically modified fish. The disadvantages of these methods lie in the delay of responses when using fish, and because it is not possible to extrapolate the results found to the environment once genetically modified organisms are used. In this scenario, we are looking for bioassays that allow a fast and environmentally sound biomonitoring.
