This book was released on 2003 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the development of Canadian water quality guidelines for the nitrate ion for the protection of aquatic life. It contains a review of technical background information on the chemical & physical properties of nitrate & nitrate salts, the nitrogen cycle, natural & anthropogenic sources, fate & behaviour of nitrate in the environment, nitrate environmental concentrations, and effects of nitrates on aquatic organisms (including fish, plants, invertebrates, and semi-aquatic mammals & birds). The final section sets out nitrate concentration guidelines to protect fresh & marine water quality and aquatic life, and provides guidance on the application of the guidelines. Appendices include tables that summarize freshwater & marine toxicity studies.
Download or read book Canadian Environmental Quality Guidelines for Nonylphenol and Its Ethoxylates written by Canada. 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.
Download or read book Protocol for the Derivation of Canadian Sediment Quality Guidelines for the Protection of Aquatic Life written by Canadian Council of Ministers of the Environment and published by . This book was released on 1995 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Sediments provide habitat for many benthic and epibenthic organisms. They also influence the environmental fate of many chemical substances in aquatic ecosystems by acting as both sinks and subsequently sources of substances that have entered the aquatic environment. This document outlines the procedures that are set out for deriving scientifically sound national sediment quality guidelines for the protection of aquatic life. Introductory guidance is also provided on how these guidelines are intended to be used in conjunction with other types of information"--Abstract.
Download or read book Membrane Technologies for Heavy Metal Removal from Water written by Juhana Jaafar and published by CRC Press. This book was released on 2024-02-12 with total page 533 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers lucid treatment of fundamental concepts related to potential applications and prospects of different membranes for wastewater decontamination by removing heavy metals. Divided into four sections, it provides an overview of different sources of water contamination, their impacts on human health and the environment, and compares traditional methods used to nullify these impacts. Further, it covers different mature membrane technologies such as polymeric membranes, poly-ceramic membranes, carbon-based membranes and many more, followed by pertinent case studies. Features: Focuses on the removal of heavy metals using membrane-based technologies. Discusses pertinent criteria to select suitable membranes. Includes feasibility studies and applications of different mature and emerging membranes. Describes heavy metals' occurrence and transport in an aqueous system with an overview of the adverse effects. Reviews challenges and opportunities associated with using different membranes. This book is aimed at graduate students and researchers in materials science, water engineering and wastewater treatment.
