With the increasing number and volume of chemicals used in modern life, their adverse effects on human health aquatic organisms have increased concerns as well. To formulate appropriate management plans, amounts/volumes emitted these must be regulated. However, no data are available use most chemicals, particularly daily-use such pharmaceuticals personal care products (PPCPs). Herein, we tested...

A high throughout semi-quantification method for screening nearly 900 organic contaminants (OCs) in river sediments has been developed. For most OCs tested, concentrations calculated from the proposed semi-quantification method deviated from actual values by a factor of 4. The overall recovery tests indicated that most OCs can be successfully extracted from sediments with recovery rates from 84...

Abstract. A novel coating for solid-phase microextraction (SPME) fibers was manufactured by using a mixture of 1-decyl-3methylimidazolium tetrafluoroborate ionic liquid and commercial adhesive deposited on an etched stainless-steel support. The new characterized applying optical electron microscopy, infrared spectroscopy its extraction capacity also evaluated. tested as model analytes some phar...

The extensive use of pharmaceuticals and personal care products (PPCPs) causes high concentrations pharmaceutical metabolites to exist in aquatic environments. Though the removal parent PPCPs has raised concerns, degradation was rarely investigated. In this study, 4-acetylaminoantipyrine (4-AAA), a typical dipyrone metabolite frequently detected worldwide surface water wastewater, initially stu...

Pharmaceuticals and personal care products (PPCPs) are a group of emerging chemicals of environmental concern that have remained largely unrecognized until recent advances in low level analytical measurements (Cha et al., 2006; Erickson, 2002; Gros et al., 2006; Lindsey et al., 2001). The growing concern over the occurrence and fate of PPCPs has been attributed not only to the induction of adve...

Environmental exposure risk to different xenobiotics, which can potentially alter the function of endocrine system, remains a great health and safety concern for aquatic species humans. Steroid hormones, pharmaceuticals personal care products (PPCPs) have been identified as important contaminants due their widespread occurrence in surface waters disrupting properties. Heavily populated areas So...
