OIL INDUSTRY – ANALYSIS, EFFECT AND REMOVAL OF HEAVY METALS

In petroleum industry, the exploration of fuel from the source rocks brings about the heavy metal pollution. Heavy metal sources include oil spillage. The heavy metal pollution is prominent at terminals, tanker accidents and spills due to wars, offshore oil exploration and land based industrial and urban sources, recreational and agricultural development. Removal of heavy metals such as Cu, Pb, Zn, Cd, Fe, Mn, and Ni continues to be important area of research. Studies indicate that there has been considerable development in analysis for heavy metal detection. Also various methods such as biosorption, adsorption and other physicochemical methods can be used for heavy metal removal.
