In addition, each-day measurements were taken at an urban background location.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>We found that median PNC exposures were highest in diesel buses (38,500 particles\/cm3) and for cyclists along the high-traffic intensity route (46,600 particles\/cm3) and lowest in electric buses (29,200 particles\/cm3). Median PM10 exposure was highest from diesel buses (47 \u03bcg\/m3) and lowest along the high- and low-traffic bicycle routes (39 and 37 \u03bcg\/m3). The median soot exposure was highest in gasoline-fueled cars (9.0 \u00d7 10\u22125\/m), diesel cars (7.9 \u00d7 10\u22125\/m), and diesel buses (7.4 \u00d7 10\u22125\/m) and lowest along the low-traffic bicycle route (4.9 \u00d7 10\u22125\/m). Because the minute ventilation (volume of air per minute) of cyclists, which we estimated from measured heart rates, was twice the minute ventilation of car and bus passengers, we calculated that the inhaled air pollution doses were highest for cyclists. With the exception of PM10, we found that inhaled air pollution doses were lowest for electric bus passengers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
