Toxicity Profile

Route of Exposure

Oral (2) ; inhalation (2) ; dermal (2)

Mechanism of Toxicity

Petroleum distillates are central nervous system depressants and cause pulmonary damage. (1)

Metabolism

Volatile hydrocarbons are absorbed mainly through the lungs, and may also enter the body after ingestion via aspiration. (1)

Toxicity Values

Not Available

Lethal Dose

Not Available

Carcinogenicity (IARC Classification)

No indication of carcinogenicity to humans (not listed by IARC).

Uses/Sources

Heptanes may be found in gasoline and are widely used as solvents. They are also sold as fuel for outdoor stoves. (3)

Minimum Risk Level

Not Available

Health Effects

Petroleum 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, 4)

Symptoms

Heptane 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. (5)

Treatment

Treatment 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)
