Low-molecular-weight aliphatic amines in exhaust from catalyst-equipped cars.
Emissions from automobiles equipped with three-way catalysts were studied. Aliphatic amine emissions from the cars tested were less than 2.2 mg/mi. Emissions of monomethylamine and dimethylamine were no more than 0.3 mg/mi and 0.1 mg/mi respectively. It is unlikely that any standard gasoline-propelled cars emit significant quantities of amines.
