Evidence of the link: air pollution and asthma

Long-term exposure to high levels of road traffic and ozone significantly increases the risk of asthma symptoms, asthma attacks or the need for use of asthma medications, according to a new study published in the European Respiratory Journal
The study strengthens the evidence from previous studies on the link between long-term exposure to outdoor pollution and asthma in adults.
It also offers new insights in to what the underlying mechanisms are, by examining the concentration of 8-isoprostane (8-iso), which is exhaled in the breath and believed to be a biological marker of tissue damage in the lungs.
