From 1944-1971, the Hanford Reach of the Colombia River in Washington State received quantities of radioisotopes, heat and chemicals from up to 8 plutonium reactors. Subsequently, from 1971-1984 the same part of the river provided cooling water for 3 power-production facilities. Environmental concerns promoted a series of continuing studies to examine various potential adverse effects. No significant impairment of the rivers ecosystem was detected. This book reviews these studies and places them in a historical framework. It provides a unique overview of studies made over a 40-year period which are now scattered through various published and unpublished documents. It should be of interest to all those concerned with aquatic ecology and environmental concerns.

The developments in information technology in the last decades of the 20th century have fundamentally changed the way in which scientific information is being communicated and used. A scientific discipline where the impact of these changes has been particularly significant is (bio)chemistry. Up to less than 25 years ago, molecular modeling was a hardly-existent computational chemistry niche, only practiced at those few institutes that could afford the very expensive specialised hardware. Also rapid access to not only the primary literature but, possibly even more importantly, to the factual primary data about millions of chemical compounds, to reactions, structures, and spectra, and to the g...
