Biology of Freshwater Pollution, is a highly regarded overview of the subject aimed at advanced undergraduates and professionals.  This latest edition provides an up-to-date summary of the whole field covering recent research, case studies and examples. The book begins by describing contrasting examples of pollution events.  Individual chapters then deal with the major types of pollution introducing their sources, exploring their impacts on biological systems and water resources using contemporary examples, and discussing methods for mitigating impacts.  Techniques used to investigate pollution are introduced throughout and the penultimate chapter deals extensively with the biological assessment of water quality. The final chapter looks at water resource management in the twenty-first century and the role of the biologist in that process.
