Healthy teenagers at risk of irregular heartbeats from air pollution, says study

Researchers monitored heart activity and the air breathed by more than 300 healthy US teenagers over 24-hour periods. They found that higher concentrations of fine particles called PM2.5s increased the risk of irregular heartbeats for the next two hours. The researchers examined the impact of particulate air pollution on 322 healthy teenagers about seven years after they enrolled, aged six to 12 years old, in the Penn State Child Cohort study. The British Heart Foundation estimated more than 160,000 people could die in the coming decade from strokes and heart attacks linked to air pollution.
