This report describes an effort by the Emission Control Technology Division of the EPA to establish a range of concern for hydrogen cyanide (HCN) emissions from mobile sources. A methodology was developed specifically for an evaluation of HCN. Mathematical models were used to calculate the ambient air contractions resulting from various mobile source HCN emission factors (grams/mile). In conjection with this, an HCN health effects literature search was conducted to aid in the determination of the final range of concern. The results of the available emission factor data indicate that HCN emissions are not likely to present a problem to public health. Vehicles equipped with a three-way catalyst operating under malfunction modes or low ambient temperatures, may, make a greater contribution to any potential human exposure problem.
