Abstract (EN): Throughout the production chain of oil activity there is the possibility of environmental contamination. Nanotechnologies have been used for the remediation of a wide variety of contaminants, promoting cost reduction and increased efficiency of remediation. Different nanoscale materials have been used, such as zeolites, metal oxides, carbon nanotubes and nanofibers, enzymes, various noble metals [mainly chromium, bimetallic nanoparticles (BNPS)] and titanium dioxide, especially the zero-valent iron in nanoscale (nZVI). However, few studies have been conducted to assess its potential risks to the environment. It is still also limited knowledge of factors related to the impacts of nanoparticles, but it is known that they are determined by various properties including: dissolution and aggregation potentials, surface properties, size, surface area, environment characteristics etc. that could determine ecotoxicological effects, including oxidative stress in microorganisms, plants, invertebrates and fish. This work, narrative revie on nanomaterials used in the remediation of contaminated soils, is part of a larger project, with the intent of evaluation of potential damage to the environment and human health caused by the use of nanomaterials in remediation of soils contaminated with hydrocarbons.
