Toxicity Profile
Route of ExposureOral (3) ; inhalation (3) ; dermal (3)
Mechanism of ToxicityPetroleum distillates are central nervous system depressants and cause pulmonary damage. (1)
MetabolismVolatile hydrocarbons are absorbed mainly through the lungs, and may also enter the body after ingestion via aspiration. (1)
Toxicity ValuesLD50: 222 mg/kg (Intravenous, Mouse) (2) LC50: 75 g/m3 over 2 hours (Inhalation, Mouse) (2)
Lethal DoseNot Available
Carcinogenicity (IARC Classification)N-Heptane is found in gasoline, which is possibly carcinogenic to humans (Group 2B). (8)
Uses/SourcesHeptanes may be found in gasoline and are widely used as solvents. They are also sold as fuel for outdoor stoves. (6)
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. (1, 7)
SymptomsHeptane affects the central nervous system and may cause lightheadedness, giddiness, stupor, vertigo, incoordination, loss of appetite, nausea, and unconsciousness. Direct skin contact with heptane may cause pain, burning, and itching. (3)
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. (1)
