The U.S. Environmental Protection Agency said Tuesday that it has concluded that most people who live in cities, suburbs and rural areas are in a zone of health risk.
The EPA found that people living in densely populated cities are exposed to elevated levels of CO2, particulate matter and other air pollutants, and they also tend to live in areas with high concentrations of ozone.
But the agency said it can’t make any blanket judgments about the health of people living near factories, mines and other industrial sites.
That’s because it can take years for scientists to analyze the data and draw conclusions about the risk posed by pollution.”EPA’s study is preliminary and we do not yet have all the data that will be necessary to support our conclusion,” said EPA spokeswoman Stephanie Kappel.
The agency says it expects to release its final report in the next few weeks.
