Pollution mitigation for hydrocarbons of petroleum through the bioremediation | A mitigação da poluição para hidrocarbonetos de petróleo através da biorremediação

Abstract

Environmental contamination by hydrocarbons resulting from activities related to the oil sector is one of the great problems of our time and with the growth of production, distribution and consumption in recent years accidents involving oil or its derivatives have been increasingly steady. This environmental problems and frequent have become increasingly critical, since as can reach the soil, air and bodies of surface and underground water. Besides that, contain compounds with high level of toxicity, mobility and persistence in the environment, and generate a major ecological impact, these pollutants hinder the treatment of contaminated areas. The objective this work is to analyze from the law involved in the prevention of environmental damage this work also sought to introduce control measures and repair of the impacts caused by the oil industry, with emphasis on bioremediation technology as a mitigation measure, working in the recovery of degraded areas. Several studies developed in Brazil and the world has shown good results in restoring environments that have been polluted by hydrocarbons. It was also demonstrated the importance of the choice of technique bioremediation that followed the most used techniques for the biodegradation of hydrocarbons, both in situ and ex situ, as well as the processes involved for the bioremediation occurs effectively and safely. The development of studies like this can help generate new technologies or improve those that already exist, which is fundamental for the enrichment of new environmental decontamination projects.
