NANOMOBIL : Synthetic Silver Nanoparticles in the system Soil-Groundwater - mobility, effects on cohabitation and interaction between hydro-, pedo- and biosphere






The objective of the Nanomobil project is to study the interaction between synthetic silver nanoparticles (Ag-NP) and the biosphere, pedosphere, and hydrosphere under realistic conditions. The focus of this project is on the future hazard and risk assessment of nanoparticles in the environment. Another aim of the Nanomobil project is to investigate the effects of nanoparticles on organisms and associated effects on the environment.

In the context of the Nanomobil project the behaviour and transport of silver nanoparticles in simple and complex test systems and natural soil-biocenosis is examined. The silver nanoparticles to be studied are either stabilised with surfactants or surface coating, as they may affect the dissolution, transformation, fate, transport behaviour and ecotoxicity in different ways.


One aim of this project is transferability of the laboratory experiments to relevant scales. Therefore, complex natural biocenosis in terrestrial model ecosystems with realistic exposure conditions will be examined with environmentally relevant silver nanoparticles concentrations.

Another aspect is the examination of the long-term behaviour of silver nanoparticles under environmentally relevant conditions. This includes the accumulation and transformation of the silver nanoparticles due to interactions between hydro- and biosphere. Here, the influence of droughts and intense rain on nanoparticle transport, the influence of cultivation on the interactions of silver nanoparticles, soil materials relevant for aquifers, and appearance of silver nanoparticles as a function of time will be studied.


An important component of the project is the development of technical innovations for particle detection based on experimental studies. The main focus is on the development of methods of field-flow fractionation (FFF) to characterise the silver nanoparticles used in aqueous matrices. After the optimisation of these methods a method transfer will take place towards environmental samples. Thus, the technical innovations of the particle detection are integrated into the project and evaluated regarding their suitability for specific applications. The increase in the detection sensitivity of the field-flow fractionation (FFF) is an important point to enhance the use and versatility of the FFF method in the field of nano-toxicology.
