The question as to: why another book on marine pollution has confounded the author as it most probably will the reader. The most appealing rationale to the author is that many of the existing volumes are dedicated to describing the present situation rather than to attacking the more formidable problem of asking what we should know, in relation to what we do know, about the alteration of the ocean's chemistry by man, in order to regulate the releases of materials to the ocean. It is in this latter mood that the publication has been prepared.
A rather unusual situation exists in marine pollution problems. Most of the already identified pollutants that may jeopardize marine resources are in extremely low concentrations, both in sea water and in marine organisms, levels difficult to assay by competent chemists. As a consequence, there are very few analysts in the world capable of carrying out reliable analyses.
Thus, the small amounts of data produced by the few chemists come under intense assessment. There are less than a dozen laboratories in the world capable of measuring DDT or petroleum components in sea water. There are perhaps a similar number of laboratories that are engaged in analysis of transuranic element concentrations in the ocean system.
On the other hand, the more readily measurable heavy metals, some of which are classified as pollutants, enjoy an enormous literature. This, in one way the task of producing this book was simple, especially when focusing upon the more difficult to measure substances. Problems arose when trying to filter the substantial and significant information on heavy metal pollutants from the many numbers about their levels in marine samples, a large proportion of which appear to be random. |
