Octyl and nonylphenol ethoxylates and carboxylates in wastewater and sediments by liquid chromatography/tandem mass spectrometry.
This work presents an LC-MS-MS-based method for the quantitation of nonylphenol ethoxylates (NPEOs) and octylphenol ethoxylates (OPEOs) in water, sediment, and suspended particulate matter, and three of their carboxylated derivatives in water. The alkylphenol ethoxylates (APEOs) were analyzed using isotope dilution mass spectrometry with [(13)C(6)]-labeled analogues, whereas the carboxylated de...
متن کاملUptake of nonylphenol and nonylphenol ethoxylates by crested wheatgrass.
Nonylphenol (NP) and other hydrophobic biodegradation intermediates of nonylphenol ethoxylate (NPE) surfactants have been identified in wastewater treatment biosolids. These biosolids often are land applied, but little is known regarding the potential uptake of biosolid-derived contaminants by plants. Hydroponic experiments, 11 to 14 weeks in duration, were conducted to examine the uptake and t...
متن کاملIdentification and quantitation method for nonylphenol and lower oligomer nonylphenol ethoxylates in fish tissues.
Substantial research is currently focused on the toxicological effects of alkylphenol ethoxylates (APEs) and alkylphenols (APs) on aquatic animals. Considerable data are available on the concentrations of APEs and APs in river systems in the United States; however, few if any data are available on the tissue concentrations of fish living in these rivers. A reliable method for the analysis of no...
متن کاملSimultaneous Determination of Four Preservatives in Foodstuffs by High Performance Liquid Chromatography
Background and objectives: High concentration of preservatives in food may result in gastrointestinal disturbances whereby some patients suffering from asthma, rhinitis, or urticaria. The aim of this study is the introduction and optimization a new method for simultaneous determination of four preservatives (SB, PS, MP, PP) in foodstuff by high performance liquid chromatography. Materi...
متن کاملEnvironmental Fate and Safety of Nonylphenol Ethoxylates
lkylphenol ethoxylates are nonA ionic surfactants widely used in many institutional and household cleaning products and industrial processes. They have been popular for their effectiveness, economy and ease of handling and formulating for more than 40 years. They function as emulsifiers, detergents, wetting agents and dispersants. One of the largest application areas for alkylphenol ethoxylates...
