Book Description
This document has been prepared in response to the need for marine water quality guidelines for general water quality variables. It presents interim guidelines, summaries of existing guidelines if any, the rationale for the guidelines, and variable-specific background information, and notes gaps in data, for the following variables: debris, including floating or submerged litter, and settleable matter; dissolved oxygen; pH; salinity; temperature; and suspended solids and turbidity. For the purpose of this document, the marine environment includes shorelines, estuaries up to the freshwater limit, and nearshore and offshore waters.

Book Description
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.

Book Description
Homeostasis and Toxicology of Non-Essential Metals synthesizes the explosion of new information on the molecular, cellular, and organismal handling of metals in fish in the past 15 years. These elements are no longer viewed by fish physiologists as "heavy metals" that kill fish by suffocation, but rather as interesting moieties that enter and leave fish by specific pathways, which are subject to physiological regulation. The metals featured in this volume are those about which there has been most public and scientific concern, and therefore are those most widely studied by fish researchers. Metals such as Ag, Al, Cd, Pb, Hg, As, Sr, and U have no known nutritive function in fish at present, but are toxic at fairly low levels. The companion volume, Homeostasis and Toxicology of Essential Metals, Volume 31A, covers metals that are either proven to be or are strongly suspected to be essential in trace amounts, yet are toxic in higher doses. Metals such as Cu, Zn, Fe, Ni, Co, Se, Mo and Cr. In addition, three chapters in Volumes 31A and 31B on Basic Principles (Chapter 1, 31A), Field Studies and Ecological Integration (Chapter 9, 31A) and Modeling the Physiology and Toxicology of Metals (Chapter 9, 31B) act as integrative summaries and make these two volumes a vital set for readers. - All major essential metals of interest are covered in metal-specific chapters - Each metal-specific chapter is written by fish physiologists/toxicologists who are recognized authorities for that metal - A common format is featured throughout this two volume edition

Book Description
"A review of the literature concerning the uses, sources to the environment, environmental fate and behaviour, and toxicity of the triazine herbicide metribuzin and its effects on raw drinking water supply, freshwater aquatic life, agricultural water uses, recreational water quality and aesthetics, and industrial water supplies were examined. From the information summarized in this report, guidelines for metribuzin were formulated for the protection of these specific water uses "--Abstract
