摘要: The aim of this study is the determination of emission factors for ultrafine particles and size distribution along motorways in the Netherlands. In the experimental campaign particle number concentrations and size distribution in the size range from 13 to 583 nm were measured by condensation particle counters (CPC) and a scanning mobility particle sizer (SMPS), respectively. The measurements were taken upwind and at various distances downwind of two Dutch motorways; one site was situated about 20 km north of the city of Amsterdam (A9-motorway) in the open field, and one within the Amsterdam agglomeration (A4), near the junction with the A10. At each sampling day, concentrations of particulate matter, CO and NOx were measured over 20 to 30 min after which the mobile measurement was driving to the next location at another distance. In this study the experimental data collected at 8 days are discussed.
