Evidence of change in the trophic structure can also be found in the Baltic Sea also the main sources of nonylphenols (NP), nonylphenol ethoxylates (NPE), 

An NPE is composed of a nonyl chain, usually branched, attached to a phenol ring (hydrophobe moiety) which is combined, via an ether linkage, with one or more ethylene oxide or polyoxyethylene units (hydrophile moiety). These products are NP, nonylphenol ethoxylate (NP1EO), nonylphenol diethoxylate (NP2EO), nonylphenoxyacetic acid (NP1EC) and nonylphenoxyethoxyacetic acid (NP2EC). NPEs can be biodegraded through a mechanism of stepwise loss of ethoxy groups to form lower ethoxylated congeners, carboxylated products and NP. Many products are non-alkyl phenol ethoxylate (APE) based, and readily biodegradable with low aquatic toxicity. Dow surfactants enable: Improved environmental profile, cleaning and wetting performance in household, industrial and institutional cleaning product formulations Alkylphenol Ethoxylate Concerns • Biodegradability • Toxicity of degradation products • Bioaccumulation Structure of 4 -nonylphenol and 17β-Oestradiol .

Nonyl-phenol ethoxylates have much narrower homologue distributions than alcohol ethoxylates (ICI datasheet for Synperonic NP surfactants). 880 million pounds (4 mio metric tonnes) of alkyl phenol ethoxylates are used annually throughout the world. 80-85% are sold as nonylphenol ethoxylate (NPE), over 15% as octylphenol ethoxylate, and 1% each as

It is nonionic and provides excellent detergency, rinse-ability, and low odor. This product is suggested for use in cleaners & degreasers, prewash spotters and m nonylphenol ethoxycarboxylates under aerobic condition, before being biodegraded to nonylphenol. Shorter ethoxylate chain alkylphenols have greater toxicity than longer ones. CCME describes Toxic Equivalent Factors from Environment Canada for NPnEO (1≤n≤8) These products are NP, nonylphenol ethoxylate (NP1EO), nonylphenol diethoxylate (NP2EO), nonylphenoxyacetic acid (NP1EC) and nonylphenoxyethoxyacetic acid (NP2EC).
