Subsoil
The subsoil (B horizon) is often enriched with clay, minerals or organic matter and is therefore also referred to as illuvial horizon. It is the main area of mineralisation. In many soil types the B horizon functions as water reservoir where water soluble pollutants accumulate. Furthermore, the channels of many burrowing soil organisms penetrate the B horizon thus facilitating the contaminant dissemination. The B horizon plays a major role in the cycle of matter because the roots of many plants penetrate through the B horizon and are exposed to the accumulated contaminants. In the subsoil, the samples are taken in the first subsoil horizon of up to 40 cm depth.
