Application of solid-phase extraction coupled with freezing-lipid filtration clean-up for the determination of endocrine-disrupting phenols in fish

A high throughout semi-quantification method for screening organic contaminants in river sediments

“…In addition, enhanced OC recovery was observed by increasing polarity and/or amounts of elution solvents for each adsorbent (Fig. S3, Tables S2 and S3), which was in accordance with previous observations (Ahn et al, 2007;Turlington and McDow, 2010). However, pronounced matrix effects were observed for polar elution solvents.…”

Multi-target determination of organic ultraviolet absorbents in organism tissues by ultrasonic assisted extraction and ultra-high performance liquid chromatography–tandem mass spectrometry

“…Several protocols have been applied for lipids removal, such as HPLC fractionation [13,28], sulfuric acid digestion [42,43], freezing-lipid filtration [61], and GPC purification [4]. In this work, hexane-methanol partitioning, sulfuric acid digestion, freezing-lipid filtration, and GPC were tested to purify the ultrasonication extracts.…”

Occurrence of endocrine disrupting compounds in five estuaries of the northwest coast of Spain: Ecological and human health impact

“…APs are used as plasticizers in high density polyethylene (HDPE), polyethyleneterephthalate (PET) and polyvinylchloride (PVC) and also in the manufacture of textiles, paper and agricultural chemical products (Salgueiro-González et al, 2012a). Meanwhile, BPA is used as a monomer for the production of epoxy resins, phenol resins, polycarbonates, polyesters and lacquer coatings for food cans (Ahn et al, 2007). Because of its toxicity, the use of this pollutant in plastic infant feeding bottles manufacturing was restricted by Directive 2011/8/EU of 28 January 2011 amending Directive 2002/72/EC (Directive, 2011).…”
