Removal efficiency of estrogens by a sewage treatment plant. Endocrine disruptors have attracted the attention of the scientific community due to the problems that can cause to animals in general, when released into the
environment. Therefore, it was deemed necessary to evaluate the system treatment
of municipal sewage of a great season of Paraná, located in Curitiba, in order to
determine their potential removal of estrogens 17β-estradiol, 17α-ethinyl estradiol and estrone. We used the technique of solid phase extraction and hormones were
detected and quantified by high performance liquid chromatography. In a sampling campaign was found in increased concentrations of estrogens in the effluent
compared to the affluent. Already in another collection, it was verified that the system
employed in the Sewage Treatment Plant South Atuba (SANEPAR) obtained 99.0% efficiency in removal of 17β-estradiol and 77.8% of 17α-ethinylestradiol from the liquid phase. Estrone levels remained stable when comparing the influent with the effluent, probably due to the balance between this hormone and 17β-estradiol. |
