Researchers have cleared the air slightly over the impact of pollution, finding virtually no effect on healthy teenagers exposed to a winter of smog.

The researchers also found that staying indoors provided no protection from air pollution.

The ground-breaking study conducted in Christchurch, often tagged the worst city in New Zealand for air pollution, followed teenagers over a winter season, when emissions from wood fires are at their worst.

The lung function of 93 students boarding at Christ's College was tested morning and night.

For 26, who have asthma, it was found there were "small decreases in lung function during very high pollution days".
