National Guidelines and Standards Office and published by National Guidelines and Standards Office. This book was released on 2002 with total page 192 pages. Available in PDF, EPUB and Kindle. 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.

Book excerpt: Nonylphenol ethoxylates are a class of high-volume chemicals used as detergents, emulsifiers, wetting agents, and dispersing agents. These chemicals and their degradation products such as nonylphenol are not produced naturally, and enter the environment primarily through wastewater treatment plant effluents. This report summarizes the information critical to the assessment of these chemicals as toxic, including their identity, properties, production, and uses; entry into the environment; fate and concentrations; toxicokinetics; and effects on experimental animals and in vitro and on humans; and ecotoxicology. The report also includes an assessment under the Canadian Environmental Protection Act of these chemicals regarding their toxicity in the environment and their population exposure & human health effects.

Available in PDF, EPUB and Kindle. Book excerpt: "These guidelines explain, in detail, how notifiers determine whether a substance is subject to notification under the New Substances Notification Regulations and identify the applicable information requirements. In addition, these guidelines provide step-by-step instructions on the completion of a New Substances Notification (NSN) Form, elaborate the technical considerations of the information requirements, identify appropriate test procedures and practices, and outline how confidential information should be treated. These guidelines conclude with an explanation of how Environment Canada and Health and Welfare Canada assess the information submitted in an NSN, and what the consequences of assessment decisions are on notifiers"--Abstract.

Book excerpt: "This document provides Federal Environmental Quality Guidelines (FEQGs) for the substance phenol, 5-chloro-2-(2,4-dichlorophenoxy), also known as triclosan, an industrial chemical that does not occur naturally in the environment. FEQGs are recommendations in quantitative or qualitative terms to support federal environmental quality monitoring. FEQGs are set at a concentration so that where the concentration of a given chemical is at or below the FEQG, there is low likelihood of direct adverse effects from the chemical on aquatic life exposed via the water or sediment, or where chemicals may bioaccumulate, in wildlife (birds and mammals) that consume aquatic life"--Provided by publisher.
