![]() ![]() ![]() ![]() A study in Vancouver suggested that UFP concentrations were related to density of fast food restaurants near the monitoring sites. Emissions from motor vehicles are the principal source of UFPs in urban air. Ultrafine particles ( UFPs) have been associated with negative effects on human health. Vert, Cristina Meliefste, Kees Hoek, Gerard Outdoor ultrafine particle concentrations in front of fast food restaurants The combined data could act as proxy-indicator for authorities in estimating particle number concentrations, but cannot replace UFP monitoring. Existing PM measurement methods alone did not correspond exactly enough with the actual particle number, but we observed a link between NOx and NO2 to UFP concentration. Of particular interest was the relation of UFP to PM10 (particulate matter and nitrogen oxides (NOx, NO2 in ambient air. Correlation of Air Quality Data to Ultrafine Particles ( UFP Concentration and Size Distribution in Ambient Airĭirectory of Open Access Journals (Sweden)įull Text Available This study monitored ultrafine particles ( UFP concurrent with environmental air quality data, investigating whether already existing instrumentation used by environmental authorities can provide reference values for estimating UFP concentrations. ![]()
