"Ozone In Smog Damages Health Even At Current Level"
"Health experts lamented a move by U.S. President Barack Obama to halt rules on limiting smog pollution, saying the decision could endanger many people already susceptible to respiratory problems.
Under pressure from businesses and Republican lawmakers, the Environmental Protection Agency had delayed issuing a rule on ozone limits several times. On Friday, Obama unexpectedly told the EPA to withdraw the clean-air initiative. Even at current levels, doctors and public health groups warn that ozone, a key smog ingredient, is harmful, especially for those already suffering from lung diseases."
