Remediação e biorremediação de solos contaminados

Abstract

Increasing technological advances, as well as changes in production processes, have required changes in the market and industry, which endanger the quality of the environment, especially surface and groundwater, soil and air, hence the need to create strategies for waste management, such as appropriate infrastructures and recovery and remediation actions of areas affected by industrial accidents, among which highlight the biological techniques for remediation of contaminated soils, object of this research, oriented to identify in the literature scientific, through a descriptive research and a systematic literature review methodology, the importance of using bioremediation techniques of contaminated soils, used primarily to address contamination by heavy metals, using removing micro-organisms. Among the results of the research highlights the fact that the techniques of biological remediation of contaminated soil are promising because they reduce the impact of soil remediation processes on the environment, require less time to achieve the expected results and still represent lower costs, both in the projection and implementation of remediation processes.
