It must be taken into account in site-specific analyses that especially in clay soils the natural concentrations may be clearly higher than those measured from moraine. (2) The guideline values for metals and semimetals defined on ecological grounds are derived by adding the average natural concentration of the mineral soil to the calculatory concentration describing the acceptable ecological risk of the substance. Correspondingly, the natural concentration of the soil in the area can be taken into account in site-specific analyses if it has been analysed with a reliable method. | Gov decree here: https://faolex.fao.org/docs/pdf/fin113198.pdf | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
