title: Alkylphenol and alkylphenol-ethoxylates in carp, water, and sediment from the Cuyahoga River, Ohio.
abstract: The occurrence of alkylphenol and alkylphenol ethoxylates (APEs) was determined over a 74-mile length of the Cuyahoga River, Ohio. Measurable levels of both the octyl and nonyl forms of these abundantly used nonionic surfactants were observed with the nonylphenol (NP) plus nonylphenol ethoxylates (NPEs) typically accounting for greater than 90% of the total APEs in each sample. For all media (water, fish, and sediment) the total NPE (NP + NPE) concentrations were higher in the more urbanized downstream section of the river. Maximum water and fish values were observed immediately downstream (2.1 miles) from the discharge of the Akron WWTP located 35.31 miles from the river mouth and the sediment maxima occurred at the most downstream site near Cleveland. The ranges in concentration fortotal NPEs and their ethoxylate (EO) makeup were as follows: 32-920 ug/kg wet wt (NP 0 to 2 EO) for carp; 0.13-1.0 ug/L (NP 0 to 3 EO) for water; and 250-1020 ug/kg dry wt (NP 0 to 5 EO) for sediment. When the higher ethoxymers (NP 6 to 17 EO) were added to these sediment totals, the average total estimated NPE concentrations were 1.3-1.8 times higher.
