Study found highly elevated PM2.5 in pre-COVID-19 subway air in NE US; NYC the worst

Green Car Congress

Concentrations in some subway stations suggest that transit workers and commuters may be at increased risk according to US federal environmental and occupational guidelines, depending on duration of exposure. By comparison, aboveground air concentrations for all measured cities averaged just 16 ?g/m g/m 3 , followed by Boston at 140 ?g/m

ICL study of 39 new Euro-6 diesels finds huge variability in NOx emissions with an average 4.5x the type approval limit

Green Car Congress

Using portable emissions measurement systems (PEMS) attached to vehicle exhausts, the researchers collaborated with Emissions Analytics to measure the amount of NO x produced by the 39 Euro 6 diesel cars. Comparison of urban and motorway trip average NO x emissions (note: y axis varies). times the COPERT model estimate, rising to 2.8
