The World Health Organization claims that air pollution is responsible for around 7 million premature deaths every year. According to British researchers from the University of Surrey, England, stopping at red lights has something to do with it. They would increase by 25% the total exposure to nanoparticlesthese elements accused of decoupling the risks of lung and heart disease.
In a study reported by the site Science Daily, scientists estimate that 2% of the time spent each day by the British in their car in front of a red light. Sudden braking and acceleration would multiply by 29 the concentration rate of nanoparticles compared to segments of the road where traffic is fluid.
10 biggest threats to human health
Among other things, cars being closer to each other, drivers are more exposed to pollution. Prashant Kumar, co-author of the study, advises people driving to keep their windows closed and maintain a respectable distance from the exhaust pipe of the car in front of theirs.
The researcher points out that air pollution is one of the ten greatest threats to human health. Pedestrians are also concerned: avoid crossing the road near a red light where traffic is very dense.
