Abstract: 
The administration of medicines and especially of antibiotic active substances to livestock and the resulting input of pharmaceuticals into the environment was estimated for the state of Mecklenburg-Western Pomerania. For this purpose, orders of production and prescriptions for pharmacenticals in feed were evaluated for the period from October 2000 until September 2001. From a total of 2097 prescriptions for pharmacenticals in feed 90% were designated for pigs. In total, 16 t of medicinal active substances including 10 t of antibiotic active substances and mostly tetracyclines and sulfon-amides, were consumed. Thereby, it is assumed that 2/3 of this amount were administered as pharmacenticals in feed and 1/3 was directly prescribed for pigs, poultry and calves, respectively. Predicted environmental concentrations in manure and soils were calculated from the amounts of administered active substances by the use of a balancing model. On average, 9 (3-14) g of antibiotics and 13 (4-23) g of medicinal substances, respectively, were administered per hectare of agricultural land in 12 districts of Mecklenburg-Western Pomerania. Due to the application of veterinary medicines, residual concentrations are found in manure especially from poultry. Concentrations ranging from 0.04 to 15 mg kg(-1) were estimated. Manure application on agricultural soils would result in soil concentrations of 1.8 (0.8-2.6) mug kg(-1) of tetracyclines and of 0.7 (0.2-1.3) mug kg(-1) of sulfonamides, when degradation processes are considered. These small residual concentrations are well below the trigger value of 100 mug kg(-1) according to EMEA and were confirmed by laboratory analysis of selected soil samples. Despite manure also dust from animal housing was identified as a source of medicinal substances in the environment.
