The objective of this work was to develop analytical procedures and protocols (extraction and clean up) for the following endocrine disruptors (ED): bisphenol A, phthalate, estriol, estrone, 17b-estradiol and 17a-ethinylestradiol and other hormones in estuarine waters by UFLC-Fluorescence and to quantify them in waters from Todos os Santos Bay, Brazil. The developed method analyzes all of the mentioned ED in 12 min by using C18 column at flow rate of 0.12 mL min-1. Samples were prepared by using C18 SPE cartridges. Recoveries ranged from 72 to 106% and repeatability was < 5.3%. The detection limits for all compounds varied between 30 to 100 ng L-1. As expected, due to the large input of sewage in the coastal system, the majority of samples presented ED.
