Book Description
"Malathion is a registered insecticide and acaricide used on a wide variety of sites including agricultural and non-agricultural sites. In 2018 (the most recent year for which data are available), over 25 000 kg of malathion was sold in Canada. Malathion may be released into surface water or soil as runoff from the application site. Malathion is not usually found in drinking water sources in Canada. Low levels of malathion have been found in several Canadian provinces. The maximum reported concentrations are well below the MAC. Malathion is rarely detected in foods"--Executive summary.

Canadian Water Quality Guidelines for the Protection of Aquatic Life
Author: Canada. National Guidelines and Standards Office
Publisher:
ISBN:
Category : Aquatic ecology
Languages : en
Pages : 110
Book Description
This report focusses on four inorganic fluorides of environmental importance: hydrogen fluoride, calcium fluoride or fluorspar, sodium fluoride, and sulphur hexafluoride. It contains information on inorganic fluoride chemistry & speciation, analytical methods, natural & anthropogenic sources, fate & fluoride levels in the environment, fluoride bioaccumulation & bioconcentration, and effects of inorganic fluorides on aquatic organisms (including fish, plants, invertebrates, and semi-aquatic mammals & birds). The final section sets out fluoride concentration guidelines to protect recreational water quality, aesthetics, and aquatic life.

Water Quality for Ecosystem and Human Health
Author: Geneviève M. Carr
Publisher: UNEP/Earthprint
ISBN: 9789295039513
Category : Business & Economics
Languages : en
Pages : 132
Book Description
This document is intended to provide an overview of the major components of surface and ground water quality and how these relate to ecosystem and human health. Local, regional and global assessments of water quality monitoring data are used to illustrate key features of aquatic environments, and to demonstrate how human activities on the landscape can influence water quality in both positive and negative ways. Clear and concise background knowledge on water quality can serve to support other water assessments.

ISBN:
Category : Nature
Languages : en
Pages : 134
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.

Aquatic Pollutants
Author: O. Hutzinger
Publisher: Elsevier
ISBN: 148314514X
Category : Technology & Engineering
Languages : en
Pages : 534
Book Description
Aquatic Pollutants: Transformation and Biological Effects contains the proceedings of the Second International Symposium on Aquatic Pollutants held at Noordwijkerhout (Amsterdam), The Netherlands on September 26-28, 1977. Organized into 47 chapters, this book first describes the aquatic pollutants and their potential biological effects. Subsequent chapters elucidate chemicals with pollution potential; multidetection approach to analysis of organic pollutants in water; volatilization of pollutants from water; microbial transformations of aromatic pollutants; and photochemical transformation of pollutants in water. Other chapters address oxidation of organic compounds in aquatic systems; laboratory microcosms for use in determining pollutant stress; continuous biomonitoring systems for detection of toxic levels of water pollutants; and health aspects of water recycling practices. This book will be useful as a review of existing knowledge in this field. It will also stimulate further thought and research.

Water Quality Indices
Author: Tabassum Abbasi
Publisher: Elsevier
ISBN: 0444543058
Category : Technology & Engineering
Languages : en
Pages : 375
Book Description
This book covers water quality indices (WQI) in depth – it describes what purpose they serve, how they are generated, what are their strengths and weaknesses, and how to make the best use of them. It is a concise and unique guide to WQIs for chemists, chemical/environmental engineers and government officials. Whereas it is easy to express the quantity of water, it is very difficult to express its quality because a large number of variables determine the water quality. WQIs seek to resolve the difficulty by translating a set of a large number of variables to a one-digit or a two-digit numeral. They are essential in communicating the status of different water resources in terms of water quality and the impact of various factors on it to policy makers, service personnel, and the lay public. Further they are exceedingly useful in the monitoring and management of water quality. With the importance of water and water quality increasing exponentially, the importance of this topic is also set to increase enormously because only with the use of indices is it possible to assess, express, communicate, and monitor the overall quality of any water source. - Provides a concise guide to WQIs: their purpose and generation - Compares existing methods and WQIs and outlines strengths and weaknesses - Makes recommendations on how the indices should be used and under what circumstances they apply
