The work reported in the paper, which commenced mid-1975, has so far been concerned with the heavier hydrocarbons, i. e. those in the C//7 to C//1//2 range. Their individual concentrations at selected sites within the city have been measured as well as their diurnal variations. From these measurements it has become clear that concentrations are of similar magnitudes to those observed in larger cities of Europe and the USA. Furthermore, comparison of the relative atmospheric concentrations with the composition of petrol showed petrol - from exhaust or evaporation or both - to be a most important, it not the predominant, source of aromatic hydrocarbons in the air. The early stages of work on determining the source contributions to the overall hydrocarbon burden in the Sydney area are described and, finally, a brief summary of outdoor smog-chamber is presented.
