oil-contamination
the coating of spilled crude oil on waterbirds that destroys the waterproofing and insulating properties of their feathers, predisposing them to hypothermia and impairing flight and swimming abilities. It also blocks nares, causes aspiration pneumonia, and has toxic effects on kidneys, reproduction and the gastrointestinal tract.
oil crop
crops grown primarily for their oil production, e.g. linseed, safflower, sunflower, rapeseed.
crude petroleum oil
crude oil and its several distillates are all relished by cattle and can cause poisoning. The oil as it is extracted from subterranean deposits varies widely in its additional contents. These may be salt or sulfur and cause poisoning by those substances. Oil causes vomiting and death from aspiration pneumonia. Animals do not do well and oil stays in the gut, appearing in the feces for long periods.

Excessive intake over a long period results in hypovitaminosis A.
oil pollution
aquatic birds are worst affected because of pasting together of feathers, poisoning because of contamination of food source, blocking of nares and eyes and starvation because of unpalatability of food supply.
oil products
includes kerosene (or kerosine, or paraffin), gasoline (or petrol), diesoline and additives to lubricating oils, e.g. highly chlorinated naphthalenes; any of them may cause poisoning.
oil spill
accidental or negligent discharge of industrial oil on a body of water; effect is that the oil floats and pollutes the shore and covers aquatic birds and mammals with fatal results in most cases; salvage depends on capture of affected birds and animals and removing the oil.
