Alkylphenol ethoxylates and alkylphenols--update information on occurrence, fate and toxicity in aquatic environment.

An Environmental Assessment of Alkylphenol Ethoxylates and Alkylphenols

Aquatic toxicity of nine aircraft deicer and anti-icer formulations and relative toxicity of additive package ingredients alkylphenol ethoxylates and 4,5-methyl-1H-henzotriazoles.

Characterization of the effects of aircraft deicer and anti-icer fluid (ADAF) runoff on aquatic organisms in receiving streams is a complex issue because the identities of numerous toxic additives are proprietary and not publicly available. Most potentially toxic and endocrine disrupting effects caused by ADAF are due to the numerous additive package ingredients which vary among manufacturers a...

The Removal of Alkylphenol Ethoxylate Surfactants in Activated Sludge Systems

US EPA has finalized federal Water Quality Criteria for nonylphenol, a biodegradation intermediate of nonylphenol ethoxylates, which are commonly used surfactants. To provide information in support of this initiative, an assessment was made of the ability of wastewater treatment plants to remove these and other alkylphenol ethoxylate (APEO) surfactants that are used widely in domestic and indus...

Identification 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...

Canadian Soil Quality Guidelines for the Protection of Environmental and Human Health - Propylene Glycol

his fact sheet provides a summary of a review by the CCME Soil Quality Guidelines Task Group (SQGTG) of the implications of propylene glycol (PG) releases to Canadian soil environments. Following a review of the releases, fate and effects of PG in soils, the SQGTG opted not to develop Canadian soil quality guidelines at this time. Nonetheless, releases of PG to the environment can pose serious ...
