Abstract HEEP COPYRIGHT: BIOL ABS. The effects of gasoline aromatic and Pb content on exhaust hydrocarbon reactivity were separately investigated in a large irradiation chamber. The study emphasized the the measurement of (human) eye irritation and of photochemically produced eye irritants, particularly peroxybenzoyl nitrate. Adding tetraethyllead to an unleaded commercial gasoline did not affect exhaust reactivity. Adding aromatics to a special low-aromatic gasoline increased the reactivity criteria associated with eye irritation, but had little or no effect on other reactivity criteria such as ozone or NO2 formation. Isopropyl benzene had the greatest effect, followed by o-xylene, n-propyl benzene, ethylbenzene, toluene and benzene. Comparable tests with commerical gasolines failed to show a correlation between eye irritation and total aromatic content of the gasoline. Some of the implications of the results for the blending of future gasolines are discussed.
