RESUMO – The study of nanoparticles involves a new bias research in various areas of technology, whose production and use have been offering multiple benefits to society. However, the uncontrolled emission to the environment of nanoparticles is growing exponentially over the last decade. Thus, knowledge of the influence of nanoparticles and how they can modify the ecosystem is extremely important and an area currently limited. Therefore, it is of fundamental importance to increase the knowledge of the fate and transport of nanoparticles in soil, in particular this research will study the TiO2 nanoparticles (TiNPs). This study will carry out tests on columns with soil collected in the landfill Volta Redonda located in the state of Rio de Janeiro, Brazil. The concentrations are analyzed TiO2, as well as the distribution of the size of its aggregates by Nanoparticle Tracking Analysis (NTA).
