The 206 nm irradiation from excilamp was able to directly photo-degrade 4-nonylphenol (4-NP) and 4-octylphenol (4-OP), but it could not oxidize them completely into CO2. Under the same irradiation condition, the removal efficiency of 4-OP was higher than that of

We show that a number of alkylphenolic compounds, used in a variety of commercial products and found in river water, are estrogenic in fish, birds, and mammals. 4-Octylphenol (OP), 4-nonylphenol, 4-nonylphenoxycarboxylic acid, and 4-nonylphenoldiethoxylate were each capable of stimulating vitellogenin

A novel hyphenated method based on ultrasound-assisted dispersive liquid-liquid microextraction coupled to precolumn derivatization has been established for the simultaneous determination of bisphenol A, 4-octylphenol, and 4-nonylphenol by high-performance liquid chromatography with fluorescence detection. Different parameters that influence microextraction and
