1. Multiresidue Determination of Endocrine Disrupting Compounds in Sewage Treatment Plants (SPE-HPLC-DAD)
This work focuses on the validation and application of solid phase extraction followed by high-performance liquid chromatography (SPE-HPLC) analysis of important endocrine disruptors compounds (EDC) from different classes in highly complex wastewater matrix. The endocrine disruptors investigated included three different categories: pharmaceuticals (sulfameth

2. Cocoa Agro-Industrial Residue (Theobroma cacao) as Inducer of the Production of Fungal Laccase and Kojic Acid for Application in the Biodegradation of 17-α-Ethinylestradiol
Due to the ability to catalyze the oxidation of several substrates, the enzyme laccase has been used in several applications, among them the bioremediation of emerging pollutants. This work evaluate the capacity of the cocoa agro-industrial residue to induce the production of Pycnoporus sanguineus laccase and to apply the enzymatic extract in the biodegradat

3. Ab initio Study of 17α-Ethinylestradiol and Estrone Molecules Interacting with Single Wall Carbon Nanotube
In this work, a systematic study of 17α-ethinylestradiol and estrone molecules interacting with single wall carbon nanotube is presented by means of first principle calculations. The structural properties, binding energy, charge transfer, and electronic properties were calculated and analyzed to characterize the effect of interaction of 17α-ethinylestradio

5. DESENVOLVIMENTO E VALIDAÇÃO DE MÉTODO PARA DETERMINAÇÃO DE BISFENOL A E ETINILESTRADIOL EM AGUAPÉ E MINI-PAPIRO PROVENIENTES DE WETLANDS CONSTRUÍDAS
Bisphenol A and ethinylestradiol, both considered as endocrine disruptors, have been found in surface water and effluents from municipal wastewater supply and can cause adverse health effects on wildlife species and in human beings at extremely low level. In order to remove these compounds from wastewater, constructed wetlands has been used since it proved t

6. Action of two endocrine disrupters on the sexual differenciation of Nile tilapia
RESUMO Desreguladores endócrinos são substâncias exógenas que possuem a capacidade de alterar uma ou várias funções do sistema endócrino com efeitos adversos a saúde um organismo intacto. O objetivo principal do presente trabalho foi avaliar a ação dos desreguladores endócrinos 17β-estradiol (E2) e 17α-etinilestradiol (EE2) na diferenciação s

7. Prioritization of pharmaceuticals in urban rivers: the case of oral contraceptives in the Belém River basin, Curitiba / PR, Brazil
Resumo Esforços para priorizar produtos farmacêuticos em rios urbanos ainda são escassos no Brasil, mas as experiências europeia e norte-americana de gestão de produtos farmacêuticos em águas urbanas mostram que este foi um dos primeiros passos para reduzir e controlar este tipo de poluição. O objetivo principal desta pesquisa foi avaliar o caso de

8. Removal of synthetic sex hormones by hydrothermal carbonization
ABSTRACT One of the most prominent fields of environmental chemistry is the study and the removal of micro-pollutants from aqueous matrices. Analytical techniques for their identification and quantification are becoming more sensitive and comprehensive and, as a result, an increasing number of drugs have been detected in environmental samples. However, the l

9. Suspended and Immobilized TiO2 Photocatalytic Degradation of Estrogens: Potential for Application in Wastewater Treatment Processes
This work evaluated the photocatalytic activity of suspended TiO2, and TiO2-coated glass Raschig rings with respect to degradation of estrogens estrone (E1), 17β-estradiol (E2), and 17α-ethinylestradiol (EE2) in aqueous solutions and wastewater effluent samples. Gas chromatography/tandem mass spectrometry (GC-MS/MS) studies were carried out to identify deg

10. Sensitive Estrogens Determination in Wastewater Samples by HPLC and Fluorescence Detection
A sensitive high-performance liquid chromatography-fluorescence detection method (HPLC-FLD) was developed and validated for 17β-estradiol (E2) and 17α-ethinylestradiol (EE2) determination in wastewater samples. Sample preparation was performed by solid-phase extraction (SPE) on Hypersep C18 cartridges. Conditioning and elution solvents and sample volume we

11. REMOVAL OF ESTROGENS BY ACTIVATED SLUDGE UNDER DIFFERENT CONDITIONS USING BATCH EXPERIMENTS
AbstractWastewater treatment by deactivated and activated sludge was investigated to evaluate the removal of estrogens [estrone (E1), 17β-estradiol (E2), 17α-ethinylestradiol (EE2)] via adsorption and degradation. Different treatment conditions were used, including three mixed liquor volatile suspended solid (MLVSS) concentrations, three methanol concentra
