[affected.gif] Animals most affected
Cattle, sheep, horses, dogs.


[etiology.gif] Etiology
ingestion of hydrocarbons: petrol, diesel, solvents, oil and oil products, or of liquid insecticides which contain hydrocarbons (e.g. kerosene) to facilitate dispersion;
drinking water which has been used to wash out storage drums or containers used to transport insecticidal preparations;
inhalation either directly or, more frequently, following ingestion and regurgitation of ingested hydrocarbons.


[toxic.gif] Toxicity
Variable according to the chemical composition and nature of the hydrocarbon, its degree of refinement and other factors. Irritant agent, particularly to the lungs. Toxic effects may also result from the chemical additives present in the hydrocarbons: sulphur compounds, lead, etc. Toxic doses are not well established. Based on pulmonary exposure, the lethal dose is dependent on the nature of the hydrocarbon.

In ml/kg (as a total dose):
LD cattle 40-70 administered over 7 days.
