For **exhaust particulate matter emissions** from diesel road vehicles, the party assumes that nearly all particles emitted are within the PM,,2.5,, range, resulting in similar emission values for PM,,2.5,,, PM,,10,,, and TSP. | For **exhaust particulate matter emissions** from diesel road vehicles, the party assumes that nearly all particles emitted are within the PM,,2.5,, range, resulting in similar emission values for PM,,2.5,,, PM,,10,,, and TSP. | ||
Excumptions from this assumption can be observed for gasoline road vehicles for the years until 1997 when **additional TSP emissions** resulted **from the use of leaded gasoline** that was banned in 1997. | Excumptions from this assumption can be observed for gasoline road vehicles for the years until 1997 when **additional TSP emissions** resulted **from the use of leaded gasoline** that was banned in 1997. | ||
