Book Description
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.

Book Description
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.

Book Description
"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.

Book Description
Articles in the following subject areas are included in the Water Quality Research Journal of Canada: surface and ground water quality; polluted precipitation; wastewater treatment processes; drinking water treatment processes; laboratory tests of properties of chemicals which provide information on their aquatic fate and effects; microcosm testing which provides information on chemical fate and effects; bioaccumulation of contaminants in and from polluted aquatic ecosystems; aquatic ecotoxicology; fate of contaminant modelling in aquatic ecosystems; review articles of water pollution situation of fields of research; strategies and policies related to water pollution control. The Water Quality Research Journal of Canada is a quarterly publication. It is primarily meant to be a forum for Canadian examples of original research.

Book Description
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.

Book Description
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.
