There is need in environmental research for a book on fresh waters including rivers and lakes. Compared with other books on the topic, this book has a unique outline in that it follows pollution from sources to impact. Included in the text is the treatment of various tracers, ranging from pathogens to stable isotopes of elements and providing a comprehensive discussion which is lacking in many other books on pollution control of natural waters. Geophysical processes are discussed emphasizing mixing of water, interaction between water and the atmosphere, and sedimentation processes. Important geochemistry processes occurring in natural waters are described as are the processes specific to nutrients, organic pollutants, metals, and pathogens in subsequent chapters. Each of these chapters includes an introduction on the selected groups, followed by the physicochemical properties which are the most relevant to their behavior in natural waters, and the theories and models to describe their speciation, transport and transformation. The book also includes the most up to date information including a discussion on emerging pollutants such as brominated and phosphate flame retardants, perflurochemicals, and pharmaceutical and personal care products. Due to its importance an ecotoxicology chapter has been included featuring molecular biological methods, nanoparticles, and comparison of the basis of biotic ligand model with the Weibull dose-response model. Finally, the last chapter briefly summarizes the regulations on ambient water quality.

The book is a collection of papers presented at the conference «Russia and Norway: Physical and Symbolic Borders» held in St Petersburg in April 2005 in connection with the opening of the exhibition «Norway – Russia. Neighbours through the ages». In the book different aspects of the history of the Norwegian-Russian border are covered by historians from Moscow, St Petersburg, Arkhangelsk, Copenhagen, Cambridge, Bergen and Tromso. The papers are diverse and refer to different chronological periods. One group of articles deals with problems connected with the medieval border treaties between Norway and Novgorodian Russia, others with the diplomatic history of the border convention of 1826, as well as its effect on ethnic minorities living in the border area. One author addresses the present-day delimitation controversy between Norway and Russia in the Barents Sea. Other articles deal with symbolic borders, for example, barriers in translating Russian literature into Norwegian, and borders between the two cultures, experienced by the Russian emigrants in Norway after the Russian Revolution. And finally, there are articles without explicit references to the concept of borders, where the authors investigate in more general terms different aspects of Norwegian-Russian relations.

A level 3 Oxford Bookworms Library graded readers. Written for Learners of English by Tim Vicary. The job was too good. There had to be a problem – and there was. John Duncan was an honest man, but he needed money. He had children to look after. He was ready to do anything, and his bosses knew it. They gave him the job because he couldn’t say no; he couldn’t afford to be honest. And the job was like a poison inside him. It changed him and blinded him, so that he couldn’t see the real poison – until it was too late.
