Nature, Distribution, and Origin of Soil Materials in the Forensic Comparison of Soils... [Pg.1]

To provide a brief example of the use of some pedological and related mineralogical methods in the forensic comparison of soils... [Pg.3]

Soil formation, or pedogenesis, is a major activity for pedologists. The origins of soil attributes, distinctive horizons, and profiles must be understood to develop conceptual models for soil evolution over both long and short time periods (e.g., Smeck, Runge, and MacKintosh 1983). Such models have intuitive, predictive power in the forensic comparison of soils. [Pg.7]

The major question posed now is how can soils be used to make accurate forensic comparisons when we know that soils are highly complex and that there are thousands of different soil types in existence For example, according to the USDA, which collects soil data at many different scales, there are more than 50,000 different varieties of soil in the United States alone. Parent material, climate, organisms, and the amount of time it takes for these properties to interact will vary worldwide. First of all, soil samples must be carefully collected and handled at the crime scene and then compared by a soil scientist with forensic science experience to ensure that the soil samples can be useful during an investigation. [Pg.11]

The lead contents of 206 soil samples determined by AAS indicated that such determination provides a useful parameter for soil comparison and discrimination in forensic science (Chaperlin 1981). Soil investigations near a former smelter in Colorado revealed that historic use of arsenical pesticides has contributed significantly to anthropogenic background concentrations of arsenic on certain residential properties. A variety of forensic techniques including spatial analysis, arsenic speciation and calculation of metal ratios were successful in the separation of smelter impacts from pesticide impacts (Folkes, Kuehster, and Litle 2001). [Pg.283]
