Soils naturally contain trace elements, the concentration of which—or natural pedogeochemical background (FPGN)—results from the geology of the parent material from which the soil formed (the bedrock) and from pedogeochemical processes (weathering, leaching, washing out, migration, etc.) that can lead to redistributions (depletion or accumulation) of ETMs within soil horizons
