Endocrine-disrupting compounds (EDCs) are a group of chemicals that interfere with the endocrine system, leading to adverse effects on human health and environment. Increasing concerns over EDCs presence in various environmental compartments has driven search for greener extraction materials. Recently, use polymers natural origin (biopolymers) been demonstrated be an effective promising research direction due their undeniable advantages synthetic polymers. In this review, strategies cellulose, chitin, chitosan functionalization applicability numerous microextraction techniques have widely discussed. Following trend related reuse waste, agricultural wastes were employed isolation enrichment described. The benefits limitations using sorbents highlighted.

Steroid hormones are a class of natural and/or synthetic organic compounds widely used in human and veterinary medicine, but also known as endocrine-disrupting chemicals because their endocrine activity that makes presence water bodies reason concern. To date, many sample treatment protocols have been developed for sensitive determination, mainly entailing liquid- solid-phase extractions, which the focus this review. Most procedures last four years already simplified improved whole throughput, positive contribution can be further overall impact analytical methods. In such scenario, metric tool named AGREEprep has here applied to highlight strengths weaknesses selected procedures, critically assessing on environment according ten principles green preparation.

Among several types of emerging contaminants, the endocrine disruptors 17β-estradiol (E2) and 17α-ethinylestradiol (EE2) are particularly notable. These compounds discharged into sewage systems subsequently water bodies, as conventional wastewater treatment processes unable to effectively eliminate such pollutants. Therefore, present study aimed evaluate possibility removing from using photocatalytic activity compound Ag3AsO4. Silver arsenate was synthesized characterized, quantification hormones E2 EE2 achieved by high-performance liquid chromatography with a fluorescence detector, validation process some preliminary tests were performed on photodegradation Ag3AsO4 catalyst. Validation performed, satisfactory results achieved: r = 0.9987 (E2), 0.9984 (EE2), detection limit 5.01 0.51 15.19 1.54 coefficients variation for precision intraday interday lower than 10.9725% 11.3393%, respectively, recovery 100.15% 100.31% (EE2). In studies, showed different behavior in presence light each hormone. solution E2, it reached removal rate 35% hormone under LED light, acting photocatalyst, while EE2, 96%; both obtained after 30 min exposure visible light. When this is compared other materials, high efficiency photocatalyst persistent becomes evident. This advancement has significant implications treatment, offering promising that can mitigate environmental impacts caused disruptors.
