This book provides a scientific approach and comprehensive introduction to the subject of environmental pollution and is written in a manner which should be accessible to chemists, environmental scientists, geologists and geographers. The coverage is pollutant-centred and this serves to focus attention on the essential chemical aspects of each topic. Particular attention is paid to the transport of pollutants in the environment. The sources, chemical properties and reactions of pollutants in soils, air and water are all discussed, along with their associated toxicological effects and methods of monitoring, analysis and disposal. Readers of the book should obtain an understanding of the scientific principles of this field at a chemical level and should be able to approach the contentious issues surrounding this subject in a rational way. The book is intended for chemists, environmental scientists, geologists and geographers.
