Resumo: This work aimed to investigate the effects of the endocrine disruptors 17β-estradiol (E2) and 17α-ethinylestradiol (EE2) on Nile tilapia (Oreochromis niloticus) development, emphasizing the zootechnical and morphological aspects. The concentrations of E2 and EE2 tested were 250, 500, and 1,000 μg·L−1. The evaluated compounds were capable of producing intersex individuals and causing zootechnical damage in Nile tilapia, with a significant decrease in the condition factor as the concentrations increased. Besides, these concentrations were also able to induce the development of morphological anomalies without any significant difference between them. E2 and EE2 exposure were shown to be lethal for Nile tilapia larvae, having no effect on the incubation time and the percentage of larvae hatching. Morphological anomalies such as head shape malformation, oral malformation, operculum malformation, belly retraction, distended abdomen with fluid accumulation (ascites), exophthalmos, signs of bleeding in the belly, and curved pectoral fin radii, were also observed, which impaired the fish development.

As concentrações de E2 e EE2 avaliadas foram de 250, 500 e 1.000 μg.L−1. Os compostos estudados foram capazes de produzir indivíduos intersexo e causar danos morfológicos na tilápia do Nilo, com diminuição significativa no fator de condição, na medida em que as concentrações aumentaram em ambos os hormônios. Não foram observadas diferenças significativas no desenvolvimento de anomalias morfológicas entre as concentrações avaliadas. Também foi possível observar que as concentrações avaliadas de E2 e EE2 se mostraram letais para grande parte das larvas de tilápia do Nilo, não apresentando qualquer efeito no período de incubação dos ovos e na porcentagem de eclosão das larvas. As anomalias morfológicas mais observadas na presente pesquisa foram má formação da cabeça, má formação bucal, deformações no opérculo, retração ventral, abdômen distendido com acúmulo de líquido (ascite), exoftalmia, manchas hemorrágicas no ventre, curvatura nos raios das nadadeiras peitorais e atraso no desenvolvimento.Engenharia sanitária e ambiental2022-07-21T18:24:35Z2022-07-21T18:24:35Z2022info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfMOTA, F.
