2. Biodegradation of the Recalcitrant Endocrine Disruptor Nonylphenol
Abstract : Currently, over 100 high-volume chemicals have been classified as endocrine disrupters. One of these is nonylphenol, which was used as the model compound in this study. This substance originates mainly from the degradation of non-ionic surfactants (nonylphenol ethoxylates) which are widely used in industrial and domestic applications. READ MORE
