Top-/bottom-soil ratios and enrichment factors: What do they really show?
Original language description
High top-/bottom-soil ratios, or high values of "enrichment factors'' (EFs), are used as a proof for major anthropogenic impact on the geochemistry of the Earth surface. The idea behind calculating such ratios is that soils taken at depth or "average crust'' can provide the geochemical background for the soils collected at the Earth surface. However, a soil profile is not a closed system, element exchange between the different layers, depending on and varying with the chemical properties of the different elements, and their turnover in the biosphere is the essence of soil formation. High top-/bottom-soil ratios, or EFs, may thus highlight the geochemical de-coupling of the lithosphere from the biosphere rather than contamination. This is demonstrated by using regional data from 258 soil O- and B-horizon samples collected from the Czech Republic (76,800 km(2)). Results show no relationship between the ratios and the magnitude of anthropogenic emissions. The visible relationship between
