Advances in Water Pollution Research, Volume 1, documents the proceedings of the Second International Conference on Water Pollution Research held in Tokyo, August 1964. The past decade has seen a rapid increase in water pollution research activity in all parts of the world. The vast research activities in Japan and the impact of this activity on all of Southeast Asia led to the unanimous decision to hold the Second International Conference in Japan. This volume contains 16 papers that deal with topics such as the microbiological and virological aspects of water pollution; the impact of toxic substances on fish; research on heavy metal pollution; residual toxic effects of organic phosphorus insecticides in water; and mechanisms of uptake and release of radionuclides by stream sediments. Also included are the opening address by Conference President, Dr. Korokuro Hirose, Professor Emeritus of Tokyo University, and keynote address by A. Key of the Ministry of Housing and Local Government, London, England.
