Most of the current studies focus on the transport of contaminants by engineered nanoparticles (ENPs) in regular porous media because of the potential environmental risk associated with enhanced migration rates of contaminants due to the mutual interactions of the nanoparticles [1, 7,8] .
The main advances of this study compared with previous one are the new detailed NTA analysis and the combination of NPTiO2 and NPSiO2 interactions with a natural soil, which is used in the controlled landfill layer.
