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.
