Clean air improves kids' lung, says study

Washington: Cleaner air results in better lung health in children, says a new study done in California. Efforts to enhance air quality can improve children's lung health in the short term and might also make a difference for those kids later in life, showed the study. Children in California were found to experience improved lung function as levels of air pollution in the state declined between 1994 and 2011. The health improvements seen in the teens were most closely linked to lower concentrations of nitrogen dioxide and particulate matter, whereas the changes were linked to a lesser extent with ozone.
