From the study.
"Our study showed that the total PM EF of the EV was significantly lower than that of the gasoline ICEV and diesel ICEV, when secondary exhaust PM was included in the determination. Therefore, the replacement of ICEVs by EVs can improve air quality and reduce the adverse impact of PM on human health."
