Studies of the occurrence, distribution and aqueous geochemistry of arsenic in the environment requires accurate and sensitive analytical measurements. In addition to the determination of total arsenic concentrations, speciation of the form in which arsenic occurs plays a major role in its chemical reactivity and toxicity. Determination of speciation includes: the distribution of oxidation stat...

Elemental analysis has played an important role in the characterization of soils since inception of the soil survey in the US. Recent efforts in analysis of trace and major elements (geochemistry) have provided necessary data to soil survey users in a variety of areas. The first part of this paper provides a brief overview of elemental sources, forms, mobility, and bioavailability; critical asp...
