Abstract
Most textbooks and journal articles contend that the stable forms in which the base metals are likely to occur in the aerobic environments are as the oxides and the carbonates. Since the base metal carbonates and oxides are fairly soluble (see Garrels and Christ 1965; Stumm and Morgan 1970), the conclusion is inescapable that, when in a dispersed form, the base metals are sorbed onto the sediment and soil particles. The dearth of pertinent thermochemical data apparently has forestalled any attempt to consider the supergene formation and stability of the base metal phosphates. Using the available (Nriagu 1974) or predictive thermochemical data, this report explores the role of the formation of base metal phosphates in the dispersion and fixation of the base metals in soils and sediments. Evidence which implicates the formation of insoluble lead phosphates in roadside soils is also considered in detail.
