“…Solid phase extraction was used to concentrate samples prior to estrogenic activity assays and ED analysis by gas chromatography. Briefly, the sample was filtered (MACHEREY-NAGEL 85/70 BF, glass fiber, 47-mm diameter, pore size 1.2 μm) in a vacuum filtration system and the pH adjusted to 3 (HCl 30% vol/vol) as according to (Guedes Maniero et al 2008;Sanson 2012;Pereira et al 2013;Queiroz et al 2014). Then, Strata X® cartridges were conditioned prior to extraction.…”

“…After drying (5 min), elution was conducted using 4 mL of acetone (4 × 1 mL) (Vetec). Finally, eluted sample was dried in nitrogen gas (N 2 ) and suspended in 1 mL of ethanol for estrogenic activity analysis and suspended in 300 μL of methanol for chromatographic analysis (EPA 2007;Guedes Maniero et al 2008;Sanson 2012;Pereira et al 2013;Queiroz et al 2014).…”

“…EDs were analyzed by a quali-quantitative gas chromatographic method as according to the peak area obtained for each compound. Chromatographic analyses were conducted in a gas chromatographer coupled to a mass spectrometer (GCMS-QP 2010 plus, Shimadzu®) by using the methodology described by Sanson (2012) and Queiroz et al (2014). GC/ MS analysis was performed after derivatization by BSTFA/ 1% TCMS in pyridine.…”

The goal of this work was to evaluate the performance of the LED irradiated photo-Fenton process on the removal of (i) estrogenic activity and (ii) seven endocrine disruptors (EDs) (4-octylphenol, 4-nonylphenol, bisphenol A, estrone, 17β-estradiol, 17α-ethinylestradiol, and estriol) from real wastewater treatment plant effluent (WWTPE). EDs are a group of contaminants of emerging concern present in WWTPE and which may be recognized by hormone receptors, thus harming animal and human health. The yeast estrogenic screen test (YES) was used to quantify estrogenic activity promoted by EDs in WWTPE samples before and after photo-Fenton treatment. Tests were performed following a factorial design with different iron (20, 40, and 60 mg L −1) and hydrogen peroxide (100, 200, and 300 mg L −1) concentrations in a laboratory scale LED photoreactor (λ = 455 nm, 1.5 L, 1.6 × 10 −6 Einstein s −1). EDs were analyzed by gas chromatography coupled to a mass spectrometer. Control experiments consisted of Fenton process, iron only, LED irradiation only, and H 2 O 2 only. Optimum experimental conditions for LED photo-Fenton resulted in 62% removal of estrogenic activity and 59% mineralization. In addition, treated WWTPE was not toxic to Aliivibrio fischeri and more than 80% of EDs were removed during LED irradiated photo-Fenton. Although Fenton process showed similar efficiency to that obtained by LED photo-Fenton, a higher volume of sludge was generated in the dark. Finally, results obtained in this study confirm the applicability of LED irradiated photo-Fenton process for improving the quality of WWTPE as an alternative to solar photo-Fenton in case solar radiation is not available, thus reducing hazards associated to WWTPE reuse or discharge.

“…A presença destas substâncias nos diversos efluentes é preocupante, pois eles podem ser considerados a maior fonte de contaminação para o ambiente. Queiroz et al (2014), o esgoto doméstico é uma matriz muito complexa e difícil de trabalhar do ponto de vista analítico, uma vez que pode conter uma diversidade de compostos orgânicos e inorgânicos, todos com maior concentração quando comparados com os contaminantes de interesse. Devido a isso, alguns desses componentes podem interferir nos resultados referentes a quantificação de contaminantes.…”
