Even a short exposure to a low amount of ultra fine particles increases the risk of cardiac arrest. This emerges from large-scale research in Japan. The researchers are urgently calling for stricter standards.
‘Our study supports recent evidence that there is no safe level of air pollution,’ said cardiologist Kazuaki Negishi of the University of Sydney (Australia), lead author of the study.
As soon as we ingest particulate matter, there is already an increased risk of cardiac arrest. Even a short exposure to a low amount of PM2.5, fine dust with a diameter of 2.5 micrometres, is enough to increase the risk.
