Aišku kad yra, bet PM2.5 yra didžioji dalis taršos. Bent jau jeigu yra tvarkingas variklis, neišpjautas katalizatorius ir t.t.

Nu tarkim, bet teiginis kad is EV yra daugiau PM2.5 vistiek yra melas ir demagogija:Parašė MedinisStrazdas Rodyti pranešimą
When only primary exhaust PM emissions were considered in vehicles equipped with non-asbestos organic (NAO) brake pads, the total PM10 EF of the EV (47.7–49.3 mg/V·km) was 10–17 % higher than those of the gasoline ICEV (42.3 mg/V·km) and diesel ICEV (43.2 mg/V·km). However, in vehicles equipped with low-metallic (LM) brake pads, the total PM10 EF of the EV (49.2–57.7 mg/V·km) was comparable or lower than those of the gasoline ICEV (56.3 mg/V·km) and diesel ICEV (57.2 mg/V·km). When secondary PM emissions were included, the EF was always significantly lower for the EV than ICEVs. The total PM10 EF of the EV (47.7–57.7 mg/V·km) was lower than those of the gasoline ICEV (56.5–70.5 mg/V·km) and diesel ICEV (58.0–72.0 mg/V·km). Since secondary PM particles are mostly of submicron size, the EFs of the PM2.5 fraction of the ICEVs (28.7–33.0 mg/V·km) were two times higher than those of the EV (13.9–17.4 mg/V·km).Comment

Ne, jie matavo absoliuciai viska - padangas, kaladeles, varykli etc. Isvada - EV yra geriau nei VDV PM2.5 tarsos atveju, net prie ju didesnes mases. Todel EV yra daug geriau zmoniu sveikatai visais tarsos aspektais: NO2, CO, ir PM2.5Parašė MedinisStrazdas Rodyti pranešimą
Va citata is tyrimo:
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 healthComment
