Pollution solutions

This new edition of Environmental Chemistry benefits from the reorganisation of subject matter and covers a wider range of topics than the first. Colin Baird addresses anthropogenic influences on the environment and consequently the text deals mainly with pollution. Appropriately, however, some background on processes in the natural environment is included. Atmospheric chemistry is covered, extending to ozone depletion, photochemical smog and global warming. A discussion of projected future trends in emissions links to energy generation by conventional and alternative means. Next, the impact of toxic chemicals, including synthetic organic compounds and metals, is covered, followed by discussion of water chemistry and the purification of polluted water. Finally, a resume of treatment strategies for solid wastes and contaminated soils is presented with an outline of the new area of green chemistry.

The book is well presented and demonstrates clearly the importance of fundamental concepts in chemistry to our understanding of complex processes in the environment. It includes short transcripts of interviews with specialists and directs the reader to sources of further information. The text will be of value to undergraduate students studying environmental chemistry or environmental sciences.
