Toxicity Profile
Route of ExposureOral (7) ; inhalation (7) ; dermal (7)
Mechanism of ToxicityOrganobromide compounds, especially alkylbromides are strong alkylating agents. Consequently they can randomly modify the surfaces of proteins and lipids, leading to the disruption of enzyme, transporter or membrane functions. One of the most probable protein targets is the TRPA1 ion channel that is expressed in sensory nerves (trigeminal nerve) of the eyes, nose, mouth and lungs. Alkylation of DNA by alkylbromides may also lead to mutations.
MetabolismNot Available
Toxicity ValuesLD50: 1350 mg/kg (Oral, Rat) (2) LD50: 1750 mg/kg (Intraperitoneal, Rat) (3) LC50: 27 000 ppm over 1 hours (Inhalation, Rat) (3)
Lethal DoseNot Available
Carcinogenicity (IARC Classification)3, not classifiable as to its carcinogenicity to humans. (8)
Uses/SourcesBromoethane is an industrial chemical.
Minimum Risk LevelNot Available
Health EffectsBromoethane is a weak carcinogen and a strong lachrymator. Studies in rodents indicated that chronic exposure to moderately high levels of bromoethane can lead to marginal increases in lung, adrenal and brain neoplasms (1)
SymptomsInhalation can cause drowsiness and excessive amounts can lead to unconsciousness. Exposure to eyes can lead to redness and pain.
TreatmentEYES: irrigate opened eyes for several minutes under running water. INGESTION: do not induce vomiting. Rinse mouth with water (never give anything by mouth to an unconscious person). Seek immediate medical advice. SKIN: should be treated immediately by rinsing the affected parts in cold running water for at least 15 minutes, followed by thorough washing with soap and water. If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration.

General Function:
Temperature-gated cation channel activity
Specific Function:
Receptor-activated non-selective cation channel involved in detection of pain and possibly also in cold perception and inner ear function (PubMed:25389312, PubMed:25855297). Has a central role in the pain response to endogenous inflammatory mediators and to a diverse array of volatile irritants, such as mustard oil, cinnamaldehyde, garlic and acrolein, an irritant from tears gas and vehicule exhaust fumes (PubMed:25389312, PubMed:20547126). Is also activated by menthol (in vitro)(PubMed:25389312). Acts also as a ionotropic cannabinoid receptor by being activated by delta(9)-tetrahydrocannabinol (THC), the psychoactive component of marijuana (PubMed:25389312). May be a component for the mechanosensitive transduction channel of hair cells in inner ear, thereby participating in the perception of sounds. Probably operated by a phosphatidylinositol second messenger system (By similarity).
