Description / Table of Contents: In this book the study of natural waters is approached via a discussion, on an elementary level, of the geological, biological, physical, and anthropogenic factors which control the chemical composition of rainwater, groundwater, rivers, lakes, estuaries, and the oceans. The approach is worldwide in scope and includes quantitative estimates of the relative importance of various natural and human processes on water composition and cycling of the major elements. The book provides an integrated approach to global geochemistry and environmental problems and introduces the reader to some fundamental concepts of geology, oceanography, meteorology, environmental science, and limnology. It provides an extensive and valuable source of data for professionals while at the same time being understandable to anyone with an elementary science background.
