Description

Ambient levels of benzene, a known human carcinogen, and NOx and CO, a criteria pollutant, are dominated by emissions from automobiles. Ambient levels of benzene, NOx and CO were monitored continuously in order to predict the nationwide benzene exposure levels by using the relationship between benzene and NOx or between benzene and CO. In addition, time series variance of the data obtained in monitoring and the relationship between the data and meteorological conditions were analyzed. NOx and CO were found to be reliable predictors of benzene levels. In addition, it was found that NOx was reliable predictor of generation environment benzene levels and CO was reliable predictor of road side area benzene levels.
