This study investigated 2-wheeler exposures to CO and PM along six standardized arterial main road stretches in Bangalore city in India during morning peak (9:00-11:00) and afternoon non-peak hours (13:00-15:00) using personal samplers. Background levels on a local street carrying no traffic and away from main roads were also monitored to determine the actual contributions of vehicular traffic to exposure. Road stretches were selected to compare exposures on two types of routes - inner arterials and outer arterials with different built form characteristics. Results indicate that average background PM and CO concentrations were much lower than the respective averages of the 2-wheeler exposures as expected. While PM exposures for inner arterials were higher than for outer arterials (p=0.007), differences were much larger for CO (p |
