Résumé(disponible en anglais seulement)
The development of robust soil quality guidelines require that methods for collection and analysis of soil geochemical data be consistent and based on sound science. The methodologies described support risk assessment and include a procedure for estimating geochemical background. One aim while developing the recommendations for methodologies, was to promote the use of standardized sampling and analytical protocols for soils. The use of common protocols facilitates the comparison of soil and other data generated by different groups at different times.
The standard set of procedures proposed here serve as a starting point for data comparisons but other methodologies should be considered to provide optimal characterization of the sites being assessed. For example, if information on human exposure to metals or bioaccessibility is required, the use of additional methods of sampling and analyzing soils and other media should be considered. These include the sampling of additional soil horizons or depth intervals (e.g. A-horizon or 0-30 cm interval ) and the use of other techniques for sample preparation and analysis such as the water leach, physiologically-based extraction techniques (PBETs), and element speciation techniques (Garrett et al, 2009a; Dodd, 2011 (this release); and Parsons, 2011 (this release)).
There are four sections in the Recommendations document covering the spectrum from sample collection through data analysis. The first section has the recommendations for Site Selection, Field Sampling, and the Use of Thematic Map Layers for Data Plotting. The second covers Analytical Techniques and provides information on how the different methods of sample preparation and analysis cause variation in the resultant data. The third outlines an approach and provides a procedure or Estimating Geochemical Background. The fourth section has information on how to access existing sets of published geochemical data for Canada. At the end of this document, the Appendices provide additional information that pertains to the procedure for estimating geochemical background.
