Smoking in cars beats UNs pollution threshold by more than three times
PARIS (AFP) - Smoking in cars raises levels of dangerous fine-particle pollutants to many times the limit recommended by the world's health agency, a study published on Monday said.
Doctors in Britain measured concentrations of fine particles in cars driven by 17 people, 14 of them smokers, using an electronic monitor on the back seat.
The volunteers were asked to follow their normal smoking habits as the smoke levels in their car were monitored over three days.
Out of 104 journeys - average time 27 minutes - 63 were smoke-free.
