摘要

Traffic-related emissions, apart from emissions from fuel combustion for heating purposes, significantly deteriorate air quality in cities. The above mainly concerns areas located close to busy traffic routes. According to epidemiological studies, traffic-related emissions have an adverse health effect. This specifically affects commuters (drivers and car passengers), pedestrians as well as inhabitants of houses located near roads. The aim of this study was to determine the variations of particle number and mass concentrations along a busy road in Lublin, Poland and their impact on the particle exposure for commuters and pedestrians and also for inhabitants of houses located near roads. Mobile and fixed-site measurements were performed in the summer (June) with a focus on peak and off-peak traffic hours and road sections with low and high traffic intensity. The obtained results indicated that the highest concentrations of traffic-related pollution were measured near 4-way traffic intersections during peak hours. During peak hours, the average number concentration of ultrafine particles (PN0.1) in the road section near 4-way traffic intersections amounted to 17.2 ±13x103 pt/cm3 and was about 2 times higher than during off-peak hours. The average mass concentration of fine particles (PM2.5) was also approximately twice as high than in off-peak hours and amounted to 21.8 ±9.4 u.g/m3. Similar relations were found for other measured aerosol particles as well as with respect to particle exposure. The estimated particle doses inhaled by commuters and pedestrians within an hour near 4-way TIs in peak hours amounted to 4.3 ±3.3x109 pt/h (PN0.1) and 2.9 ±1.4 u.g/h (PM2.5). While estimating the doses inhaled by the inhabitants of premises located near the road one should take into account different fractional penetration of particles from outdoors to indoors and other important factors. Howsoever assessed, their values are relatively high and may have adverse health effects.
