||Discrepancies between rates of emission of VOC determined on an annual basis and those occurring in summer were studied, using as example areas Tampa Bay, St. Louis and Buffalo. Reactive VOC's were estimated by correcting total VOC's for methane content. A methodology for adapting VOC inventories to reflect summer emission patterns is outlined. The indicated increase in rate of emissions due to summer conditions ranged from 3 to 14 percent, as applied to the estimated annual non-methane emissions. Corrections for methane and for summer conditions did not appreciably change the order of importance of emission source categories. The effect of temperature is the principal cause of increased VOC emissions in summer. At least 80 percent of VOC's came from gasoline-powered vehicles and from evaporation of solvents and petroleum products. Vehicle exhaust emissions decrease as ambient temperature increases, but this effect is not large enough to counterbalance the enhanced gasoline losses from marketing and storage at summer temperatures. Improved controls on evaporative emissions could change the relative importance of exhaust and evaporative effects.
