Toxicity Profile
Route of ExposureOral (3) ; inhalation (3) ; dermal (3)
Mechanism of ToxicityPetroleum distillates are central nervous system depressants and cause pulmonary damage. (2)
MetabolismVolatile hydrocarbons are absorbed mainly through the lungs, and may also enter the body after ingestion via aspiration. (2)
Toxicity ValuesNot Available
Lethal DoseNot Available
Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesOctanes may be found in gasoline. (4)
Minimum Risk LevelNot Available
Health EffectsPetroleum distillates are aspiration hazards and may cause pulmonary damage, central nervous system depression, and cardiac effects such as cardiac arrhythmias. They may also affect the blood, immune system, liver, and kidney. (2, 5)
SymptomsPetroleum distillate poisoning may cause nausea, vomiting, cough, pulmonary irritation progressing to pulmonary edema, bloody sputum, and bronchial pneumonia. At high amounts, central nervous system depression may also occur, with symptoms such as weakness, dizziness, slow and shallow respiration, unconsciousness, and convulsions. Petroleum distillates are also irritating to the skin. (1)
TreatmentTreatment is mainly symptomatic and supportive. Gastric lavage, emesis, and the administration of activated charcoal should be avoided, as vomiting increases the risk of aspiration. (2)
