Scientists: Smog contributes to premature death

Short-term exposure to smog, or ozone, is clearly linked to premature deaths that should be taken into account when measuring the health benefits of reducing air pollution, a National Academy of Sciences review concludes.

The findings contradict arguments made by some White House officials that the connection between smog and premature death has not been shown sufficiently and that the number of saved lives should not be calculated in determining clean air benefits.

The report released Tuesday by a panel of the Academy's National Research Council says government agencies "should give little or no weight" to such arguments.
