A complete introduction to environmental chemistry, this book provides insight into the operation of the chemical processes near the Earth's surface. The four-part format groups together related environmental topics and introduces theoretical concepts. Part One brings together many essential basic geological, geochemical, and chemical ideas, and emphasizes the importance of oxygen to the chemistry of reactions near the Earth's surface. Parts Two and Three discuss systems depending on these reaction types, and Part Four examines the effects of human activities on elements that usually cycle...

Interest in the biological effects of ionising radiation closely followed the identification of such radiation. The realisation that DNA is the site of genetic infonnation in cells subsequently focussed attention on DNA as an important target in the lethal and mutagenic effects of ionising radiation. Thus radiation effects upon DNA became an important area for fundamental scientific studies by radiation biologists, chemists and physicists. To a first approximation, the concerns of the three disciplines can be divided by time scales: the physical process of energy deposition from photon or...
