to present information
Recent epidemiological studies have examined associations between living near major roads and different health endpoints. They find that populations living, working or going to school near major roads may be at increased risk for a number of adverse health effects. When compared to overall urban background concentrations, air quality monitoring studies have measured elevated concentrations of pollutants emitted directly by motor vehicles near large roadways. These elevated concentrations generally occur within a few hundred meters of the road, although this distance may vary depending on traffic patterns, environmental conditions, topography and the presence of near roadway urban structures.
