FOR 566: Veterinary Medicines in Soils: Basic Research for Risk Analysis

兽药可能会随着肥料的使用而进入土壤。最近，在土壤中检测到了生态上有效的抗菌兽药浓度。然而，缺乏对由此产生的风险进行全面分析的基本模型想法。关于疏水污染物环境命运的现有知识只能对极地兽药的动态做出有限的结论。对于像粪便这样的复杂有机混合物来说，额外的碳源和共溶剂对兽药结合、降解和运输的影响是很难预测的。据我们所知，粪便对土壤中这些物质的环境毒性的影响根本没有调查过。

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.
