â–º Smoldering combustion emitted larger mode particles in higher numbers than smaller mode particles, while the converse was true for flaming combustion. Highlights: â–º Size distribution, volatility, and mixing states of ultrafine particles emitted from rice straw, oak, and pine burning under different burning conditions were investigated. International Nuclear Information System (INIS) Volatility and mixing states of ultrafine particles from biomass burning Oxidative DNA damage was assessed as strand breaks and oxidized purines in mononuclear cells isolated from venous blood. Exposure contrasts of outdoor pollution were achieved by bicycling in traffic for 5 days and in the laboratory for 1 day. instruments in six 18-hr periods in 15 healthy nonsmoking subjects. We studied personal exposure in terms of number concentrations of UFPs in the breathing zone, using portable. The results indicate that biologic effects of UFPs occur at modest exposure, such as that occurring in traffic, which supports the relationship of UFPs and the adverse health effects of air pollution.Exposure to ultrafine particles ( UFPs) from vehicle exhaust has been related to risk of cardiovascular and pulmonary disease and cancer, even though exposure assessment is difficult.

We studied personal exposure in terms of number concentrations of UFPs in the breathing zone, using portable instr., particularly during bicycling in traffic.

Vinzents, Peter S MÃ¸ller, Peter SÃ¸rensen, MetteĮxposure to ultrafine particles ( UFPs) from vehicle exhaust has been related to risk of cardiovascular and pulmonary disease and cancer, even though exposure assessment is difficult. Personal exposure to ultrafine particles and oxidative DNA damage 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.
