Analysis and occurrence of endocrine-disrupting compounds and estrogenic activity in the surface waters of Central Spain

Tetrahymena pyriformis Phagocytic Activity Test for Rapid Toxicity Assessment of Aquatic Micropollutants

“…17β-estradiol was detected in surface waters within 0.037 ng/L−50 ng/L concentration range [9,26,35], while Tetrahymena pyriformis phagocytic activity assay could indicate the effect of 10 ng/L 17β-estradiol.…”

“…Because of the insufficient limit of detection of conventional ecotoxicology assays, many researchers address the development of innovative tools and sensitive biomarkers for the evaluation of the secondary adverse effects of micropollutants at environmentally relevant concentrations (ng/L-µg/L) [7][8][9][10].…”

Regulamentação do estrogênio sintético 17α-etinilestradiol em matrizes aquáticas na Europa, Estados Unidos e Brasil

“…Once consumed, the estrogen is excreted in urine and feces in its conjugated forms (sulfates and glucuronides) 21,22 . These are dumped in sewage, which later reaches aquatic environments in natura or in the form of effluents treated in sewage treatment stations 23,24,25 . Importantly, conventional sewage treatment technologies have limited ability to remove this estrogen 26,27,28,29,30,31 .…”

Determination of emerging contaminants in environmental matrices

“…On the contrary, no residues were reported in the area of Guadalfeo River (Andalucia), which is located in a sparsely populated area with scarce industrial activity and, consequently, no residues were found in the aquatic plants from this river. Among the compounds most frequently detected in water, BPA and methyl and propyl paraben, were also detected in aquatic plants, whereas triclosan and nonylphenol were not found, although they have been reported at higher levels in water from the studied area (Carmona et al, 2014;Esteban et al, 2014). A greater translocation has been reported for compounds with log Kow between 1 and 3.5, whereas compounds with higher log Kow tend to be not taken up (Eggen et al, 2013;García-Valcárcel et al, 2016).…”

“…1.12. The progression of the total ECs works published is due to the high number of works regarding the occurrence of ECs in water (freshwater, reused water and groundwater) (Aguilar et al, 2014;Carmona et al, 2014;Esteban et al, 2014). However, when silver nanoparticles (Ag-NPs) is included in the search of ECs and water, the result is only 30 papers published.…”
