If your baby started showing asthmalike symptoms, you might be a little concerned. If you knew that the wheezing was caused by air pollution, you might be outraged. Even worse, even if we were meeting current federal health standards, it wouldn't be enough to protect that baby.

The recent study, led by epidemiologist Elizabeth W. Triche of the Yale University School of Medicine, is summarized by Science News (including references). 

Triche's team recruited 691 women with 3-to-5-month-old infants from nonsmoking households around Roanoke, Va. Sixty-one moms had asthma, signaling that their babies were at high risk for developing the disease. The researchers collected daily respiratory data, as reported by the mothers, on all the children for 83 days in summer- the peak ozone season-and then correlated the infant's symptoms with outdoor measurements of several air pollutants.

As someone who works on air pollution issues, I get to hear stories from a lot of people. People have shared stories about kids with asthma, parents who got cancer from exposures at work, neighbors who got nauseous from the unavoidable accident at the plant down the street, employees who participated in illegal dumping, and just questions from average people about whether or not it is safe for them to take a walk in the morning.
