Effect of bioformulation in reclamation of crude oil contaminated soil and determination of metal contents in plants

Crude oil is of organic origin and is an extremely complex structure of hydrocarbons. Besides carbon, hydrogen, nitrogen and sulphur many other elements are present in crude oil. In oil fields, during drilling, gathering, transporting or in some other operations, some quantity of the crude oil gets spilled over the neighboring areas. The spilled crude oil affects the bio-chemical nature of the soil. As a result no vegetation occurs in those areas. Therefore, a study was made with an objective to revive the soil condition for vegetation development.
