Description:
The report describes and compares 0600 - 0900 AM nonmethane organic carbon (NM0C) compound data from 29 cities collected during summer periods of 1984 and 1985. onsiderable differences are observed in those areas that are anticipated to have different volatile organic compound emissions. Range of benzene and toluene concentrations are presented for the 29 urban areas. t appears that variation in the observed concentration range is more evident for toluene than benzene. his observation suggests that there may be more discrete sources for toluene than benzene. he paper was presented at the 1986 EPA/APCA symposium on Measurement of Toxic Air Pollutants held in Raleigh, North Carolina during April 26-30, 1986 period.
