Bioassays are among the ecotoxicologist's most effective weapons in the evaluation of water quality and the assessment of ecological impacts of effluents, chemicals, discharges, and emissions on the aquatic environment. Information on these assessment aids is needed throughout the international scientific and environmental management community. This comprehensive reference provides an excellent overview of the small-scale aquatic bioassay techniques and applications currently in use around the world.This special volume is the result of several years of collaboration between Environment Canada and Fisheries and Oceans Canada. Internationally recognized research scientists at many institutions have contributed to this state-of-the-art examination of the exciting, environmentally important field of microscale testing in aquatic toxicology.Microscale Testing in Aquatic Toxicology contains over forty chapters covering relevant principles, new techniques and recent advancements, and applications in scientific research, environmental management, academia, and the private sector.

Developed, developing and emerging economies worldwide are collectively contributing multiple stresses on aquatic ecosystems by the release of numerous contaminants. This in turn demands that basic toxicological information on their potential to harm living species be available. Hence, environmental protection programs aimed at preserving water quality must have access to comprehensive toxicity screening tools and strategies that can be applied reliably and universally. While a good number of toxicity testing procedures and hazard assessment approaches have been published in the scientific literature over the past decades, many are wanting in that insufficient detail is available for users to be able to fully understand the test method or scheme and to be able to reproduce it successfully. Even standardized techniques published in recognized international standard organization documents are often lacking in thoroughness and minutiae. Paucity of information relating to biological test methods may be consequent and trigger several phenomena including generation of invalid data and resulting toxicity measurements, erroneous interpretation and decision-taking with regards to a particular chemical or environmental issue, or simply abandonment of testing procedures. Clearly, improperly documented toxicity testing methods can be detrimental to their promotion and use, as they open the doorway to unnecessary debate and criticism as to their raison d’être. Furthermore, this situation can indirectly contribute to delaying, minimizing or eliminating their application, thereby curtailing the important role toxicity testing plays in the overall protection and conservation of aquatic ecosystems.

While toxicity testing procedures and hazard assessment approaches have been published in past decades, many are wanting in detail for users to fully understand or reproduce successfully. Small-scale Freshwater Toxicity Investigations (Volumes 1 and 2) responds to this need by providing comprehensive information on biological testing which is normally scattered and difficult to find.In Volume 1, 15 chapters on toxicity tests are described in great detail by way of a homogeneous structure that all contributors had to follow. These comprehensive texts allow readers to be informed of relevant information (background, theory, practice) linked to each bioassay. Hence, book contents can be used both for technology transfer purposes (e.g., classroom or workshop courses) and to undertake practical toxicity testing (e.g., in a private, public or university laboratory).In Volume 2, 11 chapters on hazard assessment schemes are describedin great detail by way of a homogeneous structure that all contributors had to follow. These comprehensive texts allow readers to know the different approaches/strategies, based on applying batteries of bioassays, that are being used internationally to assess the toxic potential of complex environmental media (e.g., effluents, sediments) impacted by chemical contamination stemming from human activities.
