Study: Ozone Smog Pollution Expanding
A new study provides the strongest evidence yet that ozone smog - a type of air pollution most often found in big cities - poses a major public health danger. The study found that even at low levels, ozone smog increases the risk of asthma attacks and irritation in the respiratory system; together with air pollution it can also contribute to heart attacks and strokes. Producer Zulima Palacio has the story.
