Soil organic matter and mineral content as crucial factors for the fate of tetracycline in soils

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract Soil self‐cleaning ability and bioavailability of different pollutants are strongly dependent on the soil properties. It is not easy to determine effects of individual soil characteristics because they can impact together often in a synergic effect.
