This study aimed to analyze through a systematic literature review the presence in aquatic
matrices of the natural hormones 17β-Estradiol (E2), Estrona (E1), in addition to the synthetic
hormone present in contraceptive pills, 17α-Ethinilestradiol (EE2), considered endocrine
disruptors DEs. Searches were conducted for peer-reviewed articles published from 2011 to
2021 that determined and quantitatively evaluated these hormones group in aquatic matrices,
especially surface water and crude and treated wastewater. The results demonstrated that the
most used extraction methodology is solid phase extraction (SPE) and for identification and
quantification, are liquid chromatographic techniques (LC) and gas chromatographic
techniques (CG) coupled to mass spectroscopy (DM). Estrona is the most abundant and often
detected estrogen. Existing conventional effluent treatment systems are not able to remove
concentrations of natural and synthetic hormones alone, requiring the junction of tertiary
treatment, the presence of these hormones in treated effluent discharge sites. With regard to
treatment technologies, activated sludge is the most widely used secondary treatment process.
It was also observed that the incorporation of the advanced treatment process composed of
anoxic-anaerobic membrane bioreactor, ultraviolet disinfection showed better results. The
absence ofimplementation ofeffluent treatment plants also influences the incorporation ofEDs
in the springs, so the implementation ofnew systems should be prioritized.
