Book excerpt: Nonylphenyl (NP) and NP ethoxylates (NPEs) are a group of organic chemicals that are widely used as surfactants, emulsifiers, wetting agents, and dispersants in a wide variety of industrial processes & commercial products. This document provides the rationale for development of Canadian environmental quality guidelines for NP & NPEs. It contains technical background information on the chemical & physical properties of NP & NPEs and a review of their sources & emissions in Canada, the distribution & behaviour of these chemicals in the environment, their toxicological effects on aquatic & terrestrial species, and NP/NPE guidelines developed in other jurisdictions. The information is then used to derive water, sediment, & soil quality guidelines for NP/NPEs to protect ecological receptors in each of these environmental compartments. The final sections suggest areas for future research & provide guidance on implementation of the guidelines.
