ABSTRACT
The CPA's Chemical Mass Balance Receptor Model (CMB7) was used for analysis of nonmethane
hydrocarbon source-receptor relationships in the Raleigh, North Carolina Metropolitan Statistical Area
(MSA). Three hour integrated ambient samples collected 15 km southeast of downtown Raleigh from 5-8
AM weekdays during August, 1993 were analyzed for speeiated hydrocarbons and used as inputs in the
model. Additional samples collected from 12-3 PM and 5-8 PM were also analyzed. CMB results for four
source profiles, i.e. roadway, whole gas, surface coating, and isoprene were compared with the State of
North Carolina's seasonally adjusted emission inventoryfor anthropogenic and biogenic hydrocarbon
