Trace analysis of endocrine disrupting compounds in environmental water samples by use of solid-phase extraction and gas chromatography with mass spectrometry detection

Monitoring the contents of six steroidal and phenolic endocrine disrupting chemicals in chicken, fish and aquaculture pond water samples using pre-column derivatization and dispersive liquid–liquid microextraction with the aid of experimental design methodology

“…The E3, OP and NP concentrations in aquaculture pond water were higher than most reports in natural water samples (Azzouz & Ballesteros, 2014;Iparraguirre et al, 2012;Yuan, Lia, Zhou, & Zhao, 2014;Zhang et al, 2011). The reason for high EDCs content in aquaculture pond water sample may be the abuse of banned animal feeds.…”

“…In addition, recent studies indicated that ECDs have been linked to infertility, premature puberty, developmental problems, attention-deficit hyperactivity disorder, obesity, diabetes, impaired immune function, endocrine cancers (prostate, ovarian and breast), metabolic syndrome, birth deformities and other diseases (De Coster & van Larebeke, 2012;Rogers, Metz, & Yong, 2013). In considering the great potentially adverse physiological effects of EDCs for human and wildlife, it is therefore critical to develop a reliable analytical method for EDCs analysis With regard to the analytical determination, numerous analytical methods including high performance liquid chromatography (HPLC) either with UV/FLD (Mao et al, 2004;Szymański, Rykowska, & Wasiak, 2006), HPLC-mass spectrometry (HPLC-MS or MS/MS) (Matejicek, 2012;Perez-Palacios, Fernandez-Recio, Moreta, & Tena, 2012), capillary electrophoresis (CE) (Mei et al, 2011;Regan, Moran, Fogarty, & Dempsey, 2003) and gas chromatography-mass spectrometry (GC-MS) (Azzouz & Ballesteros, 2014;Cappiello et al, 2014) have been proposed. GC-MS and HPLC-MS exhibit high sensitivity, but they are rather expensive and cannot be available in most laboratories.…”

Analytical method for the determination and a survey of parabens and their derivatives in pharmaceuticals

“…A few studies have reported the occurrence of parabens in consumer products including processed foods and personal care products (Liao and Kannan, 2014;Guo et al, 2014;Baranowska et al, 2014; Contents lists available at ScienceDirect journal homepage: www.elsevier.com/locate/envres Lokhnauth and Snow, 2005;Jaworska et al, 2005;Thomassin et al, 1997), as well as in environmental and biological samples including water, sediments, sewage sludge, soil, indoor dust, saliva, serum and urine (Piao et al, 2014;Azzouz and Ballesteros, 2014;Liao et al, 2013c;Wang et al, 2012;. However, to our knowledge, little is known on the occurrence of parabens in pharmaceuticals (Baranowska et al, 2014;Lokhnauth and Snow, 2005;Jaworska et al, 2005;Thomassin et al, 1997).…”

A new analytical framework for multi-residue analysis of chemically diverse endocrine disruptors in complex environmental matrices utilising ultra-performance liquid chromatography coupled with high-resolution tandem quadrupole time-of-flight mass spectrometry

“…Several studies have investigated the presence of EDCs in different types of samples including surface waters, wastewater, digested sludge and solid samples [10–19]. These studies have utilised different analytical techniques for both sample preparation, separation and detection.…”
