DOCTOR'S NOTE.

LONG-TERM exposure to air pollution can exacerbate lung disease as much as a daily pack of cigarettes, a study has found.

US researchers looked at how exposure to four main pollutants affected lung health in 7,071 adults aged 45 to 84 living in six US city areas. In areas with increased levels of ozone, they found an increase in emphysema roughly the equivalent of smoking a pack of cigarettes a day for 29 years.

Senior co-author Dr Joel Kaufman, from the University of Washington, said: "We were surprised to see how strong air pollution's impact was on the progression of emphysema on lung scans, in the same league as the effects of cigarette smoking, which is by far the best-known cause of emphysema."
