Particulate-Matter (PM2.5 and PM10) Apportionment for On-Road Mobile Sources

The objectives of this research are as follows: (1) to apportion, from among major sources, the contribution of on-road mobile sources of direct and indirect emissions that contribute to ambient PM 2.5 and PM 10 concentrations near roadways and (2) to determine appropriate PM 2.5 and PM 10 emission factors for use in estimating emission rates with microscale dispersion models.
