Nearly 67,000 new cases of childhood asthma, across 18 European countries, could be prevented annual if particulate pollution was cut to levels recommended by the World Health Organisation (WHO), according to new research. The WHO states that levels of fine particulate matter PM2.5, released by sources including road vehicles, should not exceed an annually average of 10 µg/m3. Earlier this year, another study estimated that 4 million new cases of asthma across the world among those aged between one and 18 annual were caused by levels of nitrogen dioxide in the air.
