It has been accepted that the aerosolic import in the soil surface can best calculated as a general average value of: the determined actual difference between compared layers; the calculated hypothetical aerosolic deposition of the element; the difference between its content in the technogennic layer and the average value for the compared cases; the difference between the layers transformed through the volume density in mg/1000 cm3; and the transformed difference (mg/1000 cm3) in mg/kg; by using the average volume density of the soil surface; by using the number of analysed cases.
