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