The stifling hot weather recently has triggered ozone action days in many
parts of the country. That means smog levels are high and the air can be
unhealthy to breathe. But the Environmental Protection Agency says it’s
making progress on cleaning up the pollutants that lead to ground-level
ozone. The GLRC’s Rebecca Williams reports:


Smog forms when pollutants mix with hot, stagnant air and sunshine. The
pollutants come mostly from cars and trucks, and power plants. Ground level
ozone can make asthma worse and can even cause permanent lung damage.


Chet Wayland is with the EPA. He says ozone concentrations are dropping as
regulations on smokestacks and tailpipes kick in.


“Ozone concentrations have decreased about 20 percent since 1980 and since 1990
they’ve actually decreased about 8 percent. I think that’s one of the things we’re seeing
even this summer, as hot as it is, we’re not seeing the levels we would’ve
seen several years ago.”


But ozone is still a major health problem. A recent EPA-funded study found
that ozone levels the agency considers acceptable can cause lung damage and
lead to premature death.
