Nanotechnology is a major innovative scientific and economic growth area. To date there is a lack about possible adverse effects that may be associated with manufactured nanomaterial in terrestrial environments. Since it is known that on the one hand carbon-based nanoparticles (CNPs) and endocrine disrupting chemicals (EDCs) strongly interact in wastewater and that on the other hand CNPs and EDCs are released together via wastewater irrigation to agricultural soils, knowledge of CNP effects on the EDC fate in the soil environment is needed for further risk assessments. Thus, initially the planned study will investigate the interaction between CNPs and EDCs as well as effects of these interactions on the EDC toxicity and biodegradability in aquatic systems. To identify the CNP/EDC interactions under realistic conditions, these aquatic systems will be modified in their electrolyte and dissolved organic carbon (DOC) composition as well as in the solution pH. Afterwards these data will be used to develop a function/model to describe the CNP/EDC interaction. Based on the characterization of CNP/EDC interaction in aquatic systems, this study will focus on the effects CNP/EDC interaction on the EDC sorption, toxicity and biodegradation in the soil environment. Since a wide range of different soil samples will be used for batch and incubation experiments the behaviour of EDCs in presence of CNPs can be directly related to the soil properties.

纳米技术是一个主要的创新科学和经济增长领域。到目前为止，还缺乏关于人造纳米材料在陆地环境中可能产生的不利影响的资料。由于已知一方面碳基纳米颗粒（CNP）和内分泌干扰物（EDCs）在废水中强烈相互作用，另一方面CNP和EDCs通过废水灌溉一起释放到农业土壤中，因此需要了解CNP对土壤环境中EDCs归宿的影响以进行进一步的风险评估。因此，最初计划的研究将调查CNP和EDC之间的相互作用，以及这些相互作用对EDC毒性和水生系统中的生物降解性的影响。为了确定现实条件下的CNP/EDC相互作用，将对这些水生系统的电解质和溶解有机碳（DOC）组成以及溶液pH值进行修改。然后，这些数据将用于开发函数/模型来描述CNP/EDC相互作用。本研究在总结CNP/EDC相互作用特点的基础上，重点研究CNP/EDC相互作用对土壤环境中EDC吸附、毒性和生物降解的影响。由于大量不同的土壤样品将用于分批和孵育实验，因此在CNP存在下，EDCs的行为可能与土壤性质直接相关。
