Dermal exposure is possible when handling leaded gasoline containing ethylene dibromide.
It has been detected at low levels in air and water. It induced skin and lung tumours in mice after skin application. In rodents, covalently bound radioactivity has been detected in the epithelial lining of a number of organs. In humans, acute high-dose exposure leads to liver and kidney damage. In rodents, inhalation exposure causes primarily proliferative lesions in nasal cavities.
