It is becoming increasingly realised that the oceans and rivers, in particular, are not unlimited reservoir into which waste can be dumped and that control of these emissions is necessary if complete destruction of the environment is to be avoided. T. R. Crompton has drawn together up-to-date information on these issues and on the relevant analytical methods needed by all experts active in environmental protection and toxicology.
