摘要：The extraordinary case of industrial pollution in Lake Orta was followed and documented by the Istituto Italiano di Idrobiologia from its very origin in 1926. Many papers were published regarding the effects of the pollution on chemistry and biology of the lake but they were scattered in various scientific journals and in a long time period. Now the time has come to draw the conclusions of our long work and the long history of the lake. We planned to publish a monographic volume, but technical reasons made it impossible to realise this project. The papers which could have formed the volume will be splitted into issues 60(1) and 60(2) of Journal of Limnology.
