Cycling in cities
“Cycling to work may seem the healthy option, but a study has shown that people riding in cities inhale tens of millions of toxic nanoparticles with every breath, at least five times more than drivers or pedestrians,” Jonathan Leake reports for The Sunday Times of London. “The research involved fitting cyclists with devices that could count the particles, mostly emitted by car exhausts, in the air they were breathing. … ‘This is the first time anyone has counted the particles while also measuring people’s breathing during city commuting. It showed that cyclists can inhale an astonishing number of pollutant particles in one journey,’ said Luc Int Panis of the transport research institute at Hasselt University in Belgium, who led the study.”
