Children near Amsterdam airport use inhalers more, study finds

As the public hearings for London Gatwick airport’s northern runway resume, researchers from the Netherlands have found greater inhaler use in children living near Amsterdam’s Schiphol airport. Stand close to a large airport and, if the wind is in the wrong direction, each cubic centimetre of air that you breathe will contain tens of thousands of ultrafine particles (UFP). Air pollution measurement equipment was installed in three primary schools, each about a kilometre from the airport fence. The researchers took weekly measurements of the lung function of 161 children at the schools and 19 asthmatic children living near the airport. With schools to the north and south of the airport, the children experienced airport UFP at different times. The children were also taught how to take their own lung measurements at home in the mornings and evening. It was these records that revealed the most significant finding from the study. Prof Gerard Hoek of Utrecht University, who led the study, said: “On days with high aviation-related UFP, children experienced substantially more respiratory symptoms and used more symptom-relieving medication.” These symptoms included coughing, wheeziness and phlegm. Wind direction alone was not a good predictor of exposure to airport UFP so it is unlikely that parents or children will have known their day-to-day exposure. UFP and soot from traffic was also associated with symptoms and changes in morning lung tests.<br/>
