Michelle Bell Pollution Quotations

This study investigates whether there is a threshold level below which ozone does not affect mortality. Our findings show that even if all 98 counties in our study met the current ozone standard every day, there would still be a significant link between ozone and premature mortality. This indicates that further reductions in ozone pollution would benefit public health, even in areas that meet regulatory requirements.

The air pollution data was collected by the Environmental Protection Agency for regulatory purposes. Weather data was collected from the National Climatic Data Center, and the mortality data is from the National Center for Health Statistics.
