“…Also in accordance with our findings are three case-control studies which used medical records to define cases of asthma and found no effect in children 32 33 34. In contrast, a recent study of Californian schoolchildren reported a significantly increased risk of wheeze and asthma among those living within 75 m of a major road,1 a similar finding to that previously reported in English schoolchildren by Venn et al 2.…”

“…The cumulative number of children in each racial category was also determined using discrete distances of 0.25, 0.5, 1, 2 and 4 miles. These values represent the most widely used buffer radii in proximity-based analyses of environmental exposure for point sources of air pollution;27 – 31 buffers of 0.25–1 mile are commonly used for vehicular sources of air pollution 32 – 35…”

“…In recent years, several epidemiological studies have reported associations between a population's proximity to high-traffic-volume roadways and adverse health effects, which include asthma and other respiratory symptoms, [1][2][3][4][5][6][7][8][9][10] birth and developmental effects, [11][12][13][14][15] premature mortality, 16 -20 cardiovascular effects, [21][22][23] and cancer. 24 -26 These studies typically compare the occurrence of adverse health effects in populations that live, work, or go to school near heavily traveled roadways.…”

A growing number of epidemiological studies conducted worldwide suggest an increase in the occurrence of adverse health effects in populations living, working, or going to school near major roadways. A study was designed to assess traffic emissions impacts on air quality and particle toxicity near a heavily traveled highway. In an attempt to describe the complex mixture of pollutants and atmospheric transport mechanisms affecting pollutant dispersion in this near-highway environment, several real-time and time-integrated sampling devices measured air quality concentrations at multiple distances and heights from the road. Pollutants analyzed included U.S. Environmental Protection Agency (EPA)-regulated gases, particulate matter (coarse, fine, and ultrafine), and air toxics. Pollutant measurements were synchronized with real-time traffic and meteorological monitoring devices to provide continuous and integrated assessments of the variation of near-road air pollutant concentrations and particle toxicity with changing traffic and environmental conditions, as well as distance from the road. Measurement results demonstrated the temporal and spatial impact of traffic emissions on near-road air quality. The distribution of mobile source emitted gas and particulate pollutants under all wind and traffic conditions indicated a higher proportion of elevated concentrations near the road, suggesting elevated exposures for populations spending significant amounts of time in this microenvironment. Diurnal variations in pollutant concentrations also demonstrated the impact of traffic activity and meteorology on near-road air quality. Time-resolved measurements of multiple pollutants demonstrated that traffic emissions produced a complex mixture of criteria and air toxic pollutants in this microenvironment. These results provide a foundation for future assessments of these data to identify the relationship of traffic activity and meteorology on air quality concentrations and population exposures.
