BIOREMEDIATION AN ECO-FRIENDLY METHOD FOR ADMINISTRATION OF ENVIRONMENTAL CONTAMINANTS
Environmental pollution is a severe concern for the world . Chemical and physical approaches to pollution mitigation are insufficient so bioremediation has been used which is one among the most secure, cleanest, the most cost-effective, and the least harmful to the environment technologies that is made through the use of a variety of biological agents including microorganisms and\or plants (i.e. phytoremediation) to degrade, remove, stabilize and reduce different pollutants resulted from various industrial and anthropogenic activities due to a lack of knowledge about the manufacture, use and disposal of hazardous substances since they are extremely harmful and have a negative influence on human. To control increasing pollution it's necessary to keep looking for new biological forms because bioremediation is still considered an emerging technology . This review's objective is to provide a complete overview of the numerous types of bioremediation agents available, the different bioremediation techniques for example Bioaugmentation, Bioventing, Biosparging, Biocomposting, Biopiles and Bioreactors were applied in different part of the world to reduce the toxicity of toxic substance, advantage and disadvantage of bioremediation techniques as well as restrictions in treating contaminants in the natural environment.
