Samenvatting
To study traffic-related air pollutants, volunteers provided with personal air sampling (PAS) equipment covered concurrently, by car or bicycle, various selected routes. These comprised two inner city routes in Amsterdam as well as a route including a tunnel on a busy highway and a rural route just south of Amsterdam. A third inner city route, a busy narrow street, was subsequently also selected, and covered by bicycle or walking. Each run lasted about one hour.
