What is ISO 21226 - Soil screening using soil magnetometry about?
ISO 21226 discusses soil quality with a focus on soil screening using soil magnetometry.
ISO 21226 specifies methods for the measurements of magnetic susceptibility of soils (κ) as an indicator of potential soil pollution/contamination with trace elements associated with technogenic magnetic particles (TMPs).
ISO 21226 describes related procedures, protocols, and guidelines to be applied as a screening geophysical method of determination of soil pollution with trace elements. The results of measurements are used for preparing the maps of the magnetic susceptibility of soils in the area of interest.
ISO 21226 is applicable to screening all TMPs-related anthropogenic emission sources including long-range transport of airborne elements, of which TMPs are carriers and indicators.
Note: ISO 21226 is not applicable to screening anthropogenic emissions not associated with TMPs, e.g., organic pollutants or emissions from agricultural sources.
Who is ISO 21226 - Soil screening using soil magnetometry for?
ISO 21226 on soil screening using soil magnetometry is useful for:
- Ecologists and conservationists
- Soil testing laboratories
- Landowners
- Researchers involved in soil sciences / agricultural researchers
Why should you use ISO 21226 - Soil screening using soil magnetometry?
The mapping of soil pollution status is generally based on geochemical methods that have apparent disadvantages, among them, despite the development of new, more sophisticated, and precise equipment. There is no satisfactory information on the extent and range of pollution in the area. This results in the need for a large number of samples to be collected, followed by expensive and time-consuming chemical analysis.
ISO 21226 provides you with the guidelines for using soil magnetometry as a screening method that is developed primarily to support the implementation of the two-stage optimized geophysical/geochemical method, of measuring the soil spatial anthropogenic pollution with airborne trace elements from the dry and wet deposition.
ISO 21226 gives you a method on the volume-specific magnetic susceptibility, κ, which reflects cumulative anthropogenic pollution of soil with trace elements, expressed as a PLI. The method is intended to serve as a screening and early warning system to be applied at any scale, from local to a large regional one, also for the investigation of a long-range airborne element transport.
