This paper reports the results of collecting and analysing samples of transport-related hydrocarbon emissions, as part of the 1990 Atlanta Ozone Precursor Monitoring Study in the USA. Motor vehicle emissions were sampled in canisters beside a roadway in a tunnel-like underpass, during periods of heavy traffic. Airport and aircraft emissions were approximated by canister samples obtained at a major airport facility. Three octane grades of petrol from six major vendors were used. All samples were analysed for their hydrocarbon content by gas chromatography and flame ionisation detection. During the analysis, detailed speciated hydrocarbon profiles were developed for use in the Chemical Mass Balance (CMB) model. The profiles presented and discussed here represent the hydrocarbon compositions of: (1) emissions from a road; (2) composite headspace petrol at two temperatures; (3) composite whole petrol; (4) whole petrol at three octane grades; and (5) emissions from an airport. The paper compares the profiles obtained with various other profiles. For example, it compares the road profile with similiar profiles in the literature, and makes recommendations about its use in the CMB model.
