 Abstract

 

ABSTRACT: One of the major environmental problems today, is hydrocarbons and heavy metal contamination of soil, resulting from industrial activities. These compounds have been known to belong to the family carcinogens and neurotoxin pollutants. Currently accepted disposal methods of incineration and burial in secured landfills can become prohibitively expensive when amount of contaminants are large. Mechanical and chemical methods generally used to remove pollutants from contaminated sites have limited effectiveness and can be expensive. Bioremediation is the promising technology for treatment of these contamination sites since it is cost effective and would lead to complete mineralization of organic contaminants into carbon dioxide, water, inorganic compounds, and cell proteins, or transformation of complex organic contaminants to other simpler organic compounds by biological agents like micro organisms. Many indigenous micro organisms in water and soil are capable of degrading hydrocarbon contaminants. This paper presents an overview of various remediation techniques, with emphasis on bioremediation as a sustainable method of polluted soil remediation.

Keywords: Bioremediation; landfills;  bio-augmentation; heavy metals; incineration.
