Description: Veterinary medicines may enter soils along with manure applications. Recently ecologically effective concentrations of antibacterial veterinary medicines have been detected in soil. However, fundamental model ideas for a comprehensive analysis of the resulting risks are lacking. Existing knowledge on the environmental fate of hydrophobic pollutants allows only for limited conclusions on the dynamics of the polar veterinary medicines. Effects of additional C sources and co-solvents on binding, degradation, and transport of veterinary medicines are hardly predictable for complex organic mixtures like manure. Effects of the manure on the environmental toxicity of these substances in soil are, according to our knowledge, not investigated at all. Therefore, it is the superimposing objective of the Research Unit to elucidate, with two different target substances (sulfadiazine and difloxacin), how the ecotoxicological effects of these substances in soil are coupled with their dynamics under the influence of manure. We recognise several open questions in the area of dynamics (e.g. degradation and metabolism, sequestration, scale-dependent redistribution), of effects (e.g. on structure and function of microorganisms, antibiotic resistant gene abundance and diversity) and particularly of the space-time coupling of dynamics and effects of the target substances in soil (from milliseconds to years and from the mineral surface to the soil profile). To answer these questions we will in the first phase identify, predominantly with laboratory and controlled field experiments, the relevant scales and processes as well as their mode of interaction in time. Hence, we will quantify the rates which control the dynamics and effects of the substances in soil alone and under the influence of manure. In a second phase the processes will be coupled, upscaled from Ìm to plot size, and their relevance further verified in a joint outdoor test. Therewith we can reveal and quantify the dominating factors and mechanisms that control the fate of the target substances in soils under the influence of manure. The Research Unit comprises of totally eight individual research teams. Four teams are dealing with the fate of the target substances in soils, three groups address the effect on soil microbes and one group connecting both through modelling.
