Resumo: Water is an essential factor in the life and environmental issues and is a current topic of extreme importance to human health. Endocrine disrupters affect the endocrine system, significantly altering the vital functions in living beings. Thus, it is essential to undertake the monitoring of aquatic systems that exposure to and bioaccumulation of these compounds is mitigated. The objective of this study is to monitor the presence of ten EDC in 60 water samples distributed by EPAL and in 24 samples of wastewater from a treatment plant wastewater, using a method of analysis previously implemented in the company's central laboratory. The analysis method used in this work was to Ultra Performance Liquid Chromatography Efficiency associated with tandem mass spectrometry (UPLC-MS/MS) using the extraction technique as solid phase extraction (SPE) and as a method of ionization ionization electrospray (ESI). The compounds under study were estriol, bisphenol A, diethylstilbestrol, estrone, estradiol, ethinyl estradiol, progesterone, octylphenol, nonylphenol and mestranol, having the analytical limits calculated for each compound used in the identification and quantification of the same in water samples under study.
