Download or read book Chemical Contaminants in Canadian Aquatic Ecosystems written by D. M. Whittle and published by Canadian Government Publishing. This book was released on 1998 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report focuses on those chemicals that persist in the Canadian environment and that are accumulated by aquatic organisms. It summarizes scientific information collected previously, with emphasis on Canadian research findings published in the last decade. The first part of the report introduces the general features of aquatic ecosystems and provides basic information on the fate and effects of chemical contaminants. The second part reviews contaminant related issues for the following geographic areas: Atlantic marine ecosystems including the St. Lawrence, Bay of Fundy, and general north-west Atlantic; freshwater ecosystems including the Great Lakes and inland waters; the Arctic marine ecosystem; and Pacific aquatic ecosystems including the British Columbia coastal ecosystem, the open coast, and some of the major rivers. All chapters discuss the major contaminant issues, important oceanographic or limnological features, biological resources, and sources of contaminants as well as contaminant trends, distribution, and effects. Current and emerging chemical contaminant issues and associated research topics are summarized at the end of each chapter. The third part is an overall assessment of current knowledge of chemical contaminants and their effects on fish and fish habitat, and identifies major current and emerging contaminant issues confronting Canada's fish and fish habitat.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Experts in the areas of water science and chemistry from the government, industry, and academic arenas discussed ways to maximize opportunities for these disciplines to work together to develop and apply simple technologies while addressing some of the world's key water and health problems. Since global water challenges cross both scientific disciplines, the chemical sciences have the ability to be a key player in improving the lives of billions of people around the world.
Download or read book Chemical Dynamics in Freshwater Ecosystems written by Frank A.P.C. Gobas and published by CRC Press. This book was released on 2018-01-18 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical Dynamics in Freshwater Ecosystems reviews the processes that control the distribution and impacts of chemical substances discharged into freshwater aquatic environments. The book focuses on the relationships between chemical emissions and the resulting ambient concentration in water, sediments, fish, benthos, plants, and other components of real aquatic ecosystems. Hydrodynamics, sediment dynamics, chemical fate processes, bioaccumulation, and food-chain transfer are major topics discussed in the book. Case studies and models are used to illustrate how quantitative predictions of chemical dynamics and behavior in the aquatic environment can be made. Chemical Dynamics in Freshwater Ecosystems is an excellent reference for aquatic toxicologists, wildlife toxicologists, wildlife biologists, environmental chemists, governmental regulators, environmental modelers, consultants, and students studying the effects of chemicals on aquatic environments.

Download or read book Strategy for Monitoring the Exposure and Effects of Contaminants in the Aquatic Environment written by L. Désilets and published by . This book was released on 1989 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes a strategy for monitoring exposure and effects of contaminants in the aqquatic environment. Past and present activities of the Water Quality Branch in relation to major water quality issues in Canada are summarized. A framework is then suggested to develop exposure and effect assessments for the issue of contaminants in water. Based on a simple conceptual model of the aquatic environment, this operational framework improves consistency in network design and monitoring programs.
Download or read book Contaminants of the Great Lakes written by Jill Crossman and published by Springer Nature. This book was released on 2020-09-17 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the globally important freshwater resource of the Great Lakes, which is currently threatened by contaminants that compromise water quality and impact its ecological and economic health. Divided into four parts, this volume covers historic, current and emerging sources of contamination from heavy metals and persistent organic pollutants to microplastics; and identifies their ecological impacts. Due to factors ranging from rapidly changing land use practices, climate change and our emerging understanding of their impact on biological, chemical and physical interactions, the effectiveness of management strategies has proven highly variable. Continued enhancements in the rate of lake recovery are required to sustain the health of the Great Lakes. Accordingly, the book also explores recent advances in contaminant detection, along with future steps forward in lake management approaches. Revealing our current knowledge gaps and providing a roadmap towards sustainable solutions, the book offers a valuable asset for scientists, managers and the public alike.

Book excerpt: This assessment documents the current status of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) in Canada's aquatic environment, based largely on scientific supporting documents to the Canadian Environmental Quality Guidelines & with updated information & data wherever available. Chapters cover the following topics: physico-chemicals properties of PCDD/Fs and their mode of toxic action; sources (natural & anthropogenic) & releases of PCDD/Fs to the Canadian environment; fate & behaviour of PCDD/Fs in aquatic systems & biota; Canadian environmental levels of PCDD/Fs in air, water, sediment, & aquatic organisms; toxic effects of PCDD/Fs observed in aquatic & semi-aquatic organisms (including water-, sediment-, & dietary-based toxicity), and the initiatives under way to manage PCDD/Fs in the Canadian environment as well as best management practices. The final section discusses emerging issues such as recent advances in waste incineration, PCDD/F treatment in the pulp & paper industry, and use of biological screening in toxicity determination.

Download or read book Inorganic Contaminants of Surface Water written by James W. Moore and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: This series is dedicated to serving the growing community of scholars and practitioners concerned with the principles and applications of environ mental management. Each volume is a thorough treatment of a specific topic of importance for proper management practices. A fundamental ob jective of these books is to help the reader discern and implement man's stewardship of our environment and the world's renewable resources. For we must strive to understand the relationship between man and nature, act to bring harmony to it, and nurture an environment that is both stable and productive. These objectives have often eluded us because the pursuit of other in dividual and societal goals has diverted us from a course of living in balance with the environment. At times, therefore, the environmental manager may have to exert restrictive control, which is usually best applied to man, not nature. Attempts to alter or harness nature have often failed or backfired, as exemplified by the results of imprudent use of herbicides, fertilizers, water, and other agents. Each book in this series will shed light on the fundamental and applied aspects of environmental management. It is hoped that each will help solve a practical and serious environmental problem.
