Abstract
Petroleum contains a high percentage of hydrocarbon in addition to containing measurable quantities of metals. The metallic constituents may be indegenous to the crude oils as oil-soluble metallo-organic compounds, as a colloid, or as a filterable suspension. Metals may be introduced into the finished petroleum products extraneously in processing or during service. In certain cases the presence of metals in oils can cause the finished products to have undesirable properties such as corrosion of refinery equipment, reduction of activity of cracking catalysts (and whose replacement is expensive) equipment deterioration and premature failures in engines (resulting from excessive wear, bearing failure and radiation leaks). Moreso, metals lost to the environment as air pollutants as a result of fuel combustion and other processes through which metals are released into the environment, pose a direct health hazard. In Nigeria today, with the developing economy, the number of vehicles are on the increase,. Thus the threatposed by environmental pollution cannot be overlooked as some of these metals if inhaled or ingested can cause physiological problems.
