Uptake 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 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...
متن کاملSeasonal changes in nonylphenol ethoxylates and their metabolites in water and sediment of urban river polluted by nonylphenol.
The concentrations of nonylphenol (NP), nonylphenol ethoxylates (NPnEOs: n = 1-15) and nonylphenoxy acetic acids (NPmECs: m = 1-10) in river water and sediment were determined seasonally at four sampling sites in the Kamo River, which is a typical urban river and was already known to be polluted by NP. In the water, the concentrations of NP, NPnEOs and NPmECs ranged from 0.13 to 3.65 microg/L, ...
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 کاملNonylphenol and nonylphenol ethoxylates in fish, sediment, and water from the Kalamazoo River, Michigan.
A survey measuring concentrations of nonylphenol (NP) and its ethoxylates (NPEs) in fish was performed in the Kalamazoo River, Michigan, USA, in 1999. Of 183 fish analyzed, 59% had no detectable NP or NPE. Detected concentrations were reported to range from 3.3 (limit of detection) to 29.1 ng NP/g wet weight. To further explore the means of exposure of NP and NPE in the fish, concentrations of ...
