Recent advancements in analytical methods for the determination of steroidal estrogen residues in environmental and food matrices

Abstract

Residue steroidal estrogens in environmental and food samples have become a cause for concern as they can affect organisms at low ppt concentrations. Analytical method development plays a key role in trace estrogen analysis due to the combination of low concentrations and complicated sample matrices. Reliable quantification of these trace level steroidal estrogens has become a major concern during the past decade. This mini review focuses on advancements in analytical methods developed for estrogen detection and quantification in environmental and food samples from 2014 -2016. A comprehensive overview of the novelties and the advantages of the recently developed sample pre-concentration, clean-up, and detection methods are discussed. During the past three years, a wide variety of sample extraction methods including, the utilization of innovative imprinted magnetic sorbents, QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) method and various microextraction methods such as Dispersive liquid-liquid micro extraction (DLLME), Thin film micro extraction (TFME), Solid phase microextraction (SPME), and Vortex assisted hollow fiber liquid-phase micro extraction (VA-HF-LPME) have been

Fabrication of Ce-doped DUT-52 as a sorbent for dispersive solid phase extraction of estrogens in human urine samples

“…So far, solid-phase extraction (SPE) has been a popular separation technique, but conventional SPE suffers from limited rates of diffusion, mass transfer and time consuming. 9 As a branch of SPE, dispersive solid phase extraction (DSPE) has overcome the limitations of conventional SPE to some extent. In this technique, sorbents are dispersed into sample solution directly, and the extraction equilibrium can be reached faster owing to the abundant contact area between adsorbents and analytes.…”

Preparation, characterization and application of double yolk–shell structure magnetic molecularly imprinted polymers for extraction of 17β-estradiol

“…However, exogenous estrogen, especially when used excessively, may interfere with the endocrine system and reproductive system, thereby affecting people's health. 1,2 In recent years, due to the illegal use of E2 in stockbreeding, the E2 residue has been successively detected in dairy products, such as milk powder. 3,4 In 2018, E2 was included in the pollutant candidate list established by the U.S. Environmental Protection Agency (U.S. EPA).…”

“…In recent years, various analytical methods, such as colorimetric, fluorescent, electrochemical, and electronic sensors, have been utilized to determine toxic ions, small molecules, biomacromolecules, and others from water system [1]. In addition, a lot of nanomaterials (polymer, nanoparticles, carbon materials, two-dimensional materials, and others) [2,3] and purification techniques (chemical precipitation, adsorption, ion exchange, membrane filtration, electrochemistry, and phytoremediation) [3,4] have been used to remove both inorganic and organic pollutants from water for wastewater purification.…”
