520	|a"This contribution is intended for publication by Blackwell Scientific Publications, Oxford, in the two-volume "Rivers Handbook" (P. Calow & G.E. Petts, eds.) which will be a reference work on the application of ecologically-sound approaches, methods and tools in river management throughout Europe and North America. The chapter provides an account of the evolution of benthic bioassessment techniques, describing traditional, alternative and new approaches. The techniques which have been implemented in Great Britain and the United States are critically evaluated, and the approaches of other countries, including Belgium, The Netherlands and Spain are also discussed. This information is required for the informed selection of the most suitable techniques to be incorporated into the "Technical Guidance Manual for Aquatic Environmental Effects Monitoring at Pulp and Paper Mills", which is currently in preparation. Similar legislation is planned next for the regulation of the mining industry. It is critical that we take this opportunity to ensure that 1990s technology is applied to the management of these industries"--Management perspective.
