Transformation and interactions of organic compounds in agricultural soils occur on soil interfaces. The research of thirteen cooperating groups aims at the systematic structural characterisation and functional exploration of reactive soil interfaces and at unravelling their role for the fate and effect of organic model chemicals that enter agricultural soils. The final goal is to gain a mechanistic understanding of the complex interplay and interdependencies of the physical, chemical and biological processes operative at these interfaces with respect to the fate of organic compounds. A fundamental aspect of the cooperation between the research groups are sophisticated joint experiments, in which organic model compounds including representatives of polycyclic aromatic hydrocarbons, alkanes, chiral and endocrine disrupting compounds as well as pesticides are used. An integral element is to study interactions with soil interfaces and metabolisation and degradation pathways by isotopic techniques. Therefore, the use of both stable and radio-labelled model compounds is essential to successfully conduct research within the cooperating projects.

农业土壤中有机化合物的转化和相互作用发生在土壤界面上。13个合作小组的研究旨在对活性土壤界面进行系统的结构表征和功能探索，并揭示它们对进入农业土壤的有机模式化学品的命运和影响的作用。最终目标是获得一个机械的理解复杂的相互作用和相互依赖的物理，化学和生物过程操作在这些界面相对于有机化合物的命运。研究小组之间合作的一个基本方面是复杂的联合实验，其中使用有机模型化合物，包括多环芳烃、烷烃、手性和内分泌干扰化合物的代表以及杀虫剂。一个不可或缺的元素是通过同位素技术研究与土壤界面的相互作用以及代谢和降解途径。因此，使用稳定的和放射性标记的模型化合物对于成功地在合作项目中进行研究至关重要。
