Aquatic chemistry is becoming both a rewarding and substantial area of inquiry and is drawing many prominent scientists to its fold. Its literature has changed from a compilation of compositional tables to studies of the chemical reactions occurring within the aquatic environments. But more than this is the recognition that human society in part is determining the nature of aquatic systems. Since rivers deliver to the world ocean most of its dissolved and particulate components, the interactions of these two sets of waters determine the vitality of our coastal waters. This significant vol ume provides not only an introduction to the dynamics of aquatic chem istries but also identifies those materials that jeopardize the resources of both the marine and fluvial domains. Its very title provides its emphasis but clearly not its breadth in considering natural processes. The book will be of great value to those environmental scientists who are dedicated to keeping the resources of the hydrosphere renewable. As the size of the world population becomes larger in the near future and as the uses of materials and energy show parallel increases, the rivers and oceans must be considered as a resource to accept some of the wastes of society. The ability of these waters and the sediments below them to accommodate wastes must be assessed continually. The key questions relate to the capacities of aqueous systems to carry one or more pollutants.

The book reports the results on the fate of POPs in the abiotic and biotic components of the aquatic environment North Pacific Ocean (include Russian part of North Pacific), possible health risks for coastal residents Pacific Ocean exposed to these hazardous pollutants are systematized. In particular, indicator organisms (fish, birds, and mammals), indicating the pollution of the region, were identified; the possible ways of xenobiotic transfer from the sea to the land are shown; the targets of POPs impact on living organisms were determined; the time of circulation of pollutants in the biosphere was determined; a list of “priority” toxicants for the region based on quality screening was compiled; the risks to human health from the consumption of contaminated aquatic organisms were assessed; the levels of POPs in the human body were measured. The book is interesting for specialists in the agro-industrial complex, aquaculture and medicine, teachers and graduate students of universities, researchers, which interested in the problems of persistent organic pollutants (POPs). There are no similar books on the study of POPs in the Russian part of the Pacific Ocean in the world literature. This book is useful to scientists of the world who study the fate of POPs.

The role of the European Community in developing environmental legislation has focused the minds of pollution control agencies and industrialists on the need for, and the evidence to support, water quality standards. This is particularly so for the Dangerous Substances Directive which has led to European standards for cadmium, mercury and lindane. Additionally the United Kingdom has published standards for six other non-ferrous metals. In this book I have sought to review the aquatic toxicity information for these and other metals, not just by the collation of the results of all the published toxicity tests, but by the critical consideration of the test techniques. A surprising proportion of the reported toxicity studies for aquatic organisms are based on unsatisfactory chemical or biological methods. That such weaknesses persist at a time of limited resources for environmental research is disappointing, especially when sound metho dologies are extensively documented and widely published. Evaluation of the critically reviewed and vetted data indicates that many of the previously accepted generalisations about the toxicity of metals to aquatic life are invalid: for instance the assumption that salmonid species of fish are more susceptible to these metals than coarse fish, or that increased water hardness decreases toxicity. Too few studies have actually sought to test such hypotheses.
