Estudo prospectivo sobre o uso da técnica de fitorremediação para recuperação de solos contaminados.

Abstract

The soils are characterized as a component collection that occupy most of the continental crust. These natural resources assume ecosystem relevance, being present in the recycling and nutrients supply to organisms. Besides that, soils form the basis construction projects and society productions, being in direct connection with human activities of extraction, exploitation and implantation. With the rise of the industrial revolution and the green revolution, soil contamination was intensified, causing socio-environmental problems. In front of this, the bioremediation emerges as a biotechnology capable of remedying such effects, highlighting phytoremediation, with the use of plants. This scenario points to the need for studies to identify and analyze the development of technological processes in the area. Then, the present study aimed to evaluate the technological development from phytoremediation processes in soils contaminated by heavy metals. To conduct this evaluation, searches were performed in the main patent databases, using the Questel Orbit® platform as a monitoring tool. The results obtained made it possible to evaluate the technological development from phytoremediation processes in soils contaminated by heavy metals.
