The oil and greases have been known to cause extensive damage to
environmental, creates risks of containing air, water, and soil with substances
that pose substantial hazards to animal and plant life death to migrating
birds, marine life, as much harmful to human life.
Improperly disposed oil percolates and creates ground water
contamination, cause damage to surface of ground soil, mixes with water
resources, killing plants, marine life, floats over water in the sea, spoiling
the beautiful beaches and a great threat to environment.
one gallon of used/waste oil can make a million gallons of fresh water
film of used/waste oils on water surface prevents oxygen from entering the
water and blocks sunlight. This makes it difficult for plants to
photosynthesize and reduces plant and animal life in water body. Oils have considerable
potential to cause environmental damage by virtue of their ability to spread over
large areas of land and water.
small concentrations of used/waste oils (50 to 100 ppm) in the wastewater can
foul sewage treatment plants, resulting in increased maintenance costs and reduced
oils applied to land can render the soil unproductive.
oils oil placed in landfill may seep through the bottom of such landfill and
subsequently contaminate groundwater supplies.
oils pollution can affect a high fish mortality rate and affect the
reproductive cycle. These considerations are important in relation to the food
chain and ultimate consumption of these fish and fish products.
the environment, used/waste oils degrade very slowly. Between 20% to 80% of
petroleum products in soil are degraded after 1 year. For waterways, only 20%
heath can affected if used/waste oils are handled improperly. Most used/waste
oils contain small amounts of materials that can cause cancer and other health
problems if these materials are inhaled and ingested. Used/waste oils can be
ingested if they get into drinking water sources and are not detected and
of used/waste oils into soil can bring changes in the biological cycles in the
soil. The presence of used motor oils in the soil inhibits plant development
since oil fills the pores between the soil particles and hampers oxygen access.
Also the metal content of surviving plants is increased. These metals inhibit
carbon mineralization, nitrogen transformations and mineralization of sulphur
10) Uncontrolled burning of used/waste oils may result in
significant levels of hazardous emissions to the environment. This may expose
humans, wildlife and vegetation to harmful substances.
