Freshwater Biological Monitoring contains the proceedings of a Specialized Conference held in Cardiff, Wales, on September 12-14, 1984. Contributors explore advances in freshwater biological monitoring, paying particular attention to the interpretation of traditional community surveillance studies by means of the modern computer and multivariate statistical techniques and how such field community responses are related to laboratory studies of pollutants. The design, validation, and use of novel monitoring systems employing plants, invertebrates, and fish are considered, along with developments in the in vitro assessment of mutagenicity of chemicals present in water. This book is comprised of 16 chapters and begins with a review of issues surrounding the tests used in biological monitoring and the ways in which the information will be used. The discussion then turns to the usefulness of the colonization sampler in collecting macroinvertebrates indicative of river water quality in lowland rivers; biological assessment of water quality and conservation evaluation in Welsh rivers; and water chemistry, benthos, and drift in a fast-flowing river. The following chapters focus on eutrophication in rivers; toxicity testing with freshwater macroinvertebrates; and compliance biomonitoring. This monograph will be of value to policymakers and environmentalists concerned with water pollution control.
