Thirty years ago, it was universally assumed that it would never be possible to do rigorously quantitative chemistry with such complicated natural mixtures as agricultural soils, aquatic sediments, natural waters, or even their components. One of the practical implications of that assumption was that the physical chemistry interactions of metal ions and organic chemicals with the natural geochemical mixtures could never be understood or described quantitatively in terms of molecular-level mechanisms. Practical chemical problems arising from the use of fertilizers and pesticides were consequently formulated in empirical or semiemperical forms. This approach led to an important practical limitation in soil chemistry and environment chemistry.
