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.
