The effects on children of smoking in a car cannot be reduced significantly by keeping the window down, according to a new study.
Opening a car window may lower the harm caused by passive smoking, but the air does not come down to "safe levels" by the act, research commissioned by NHS Greater Glasgow and Clyde (NHSGGC) revealed.
Experts from the Scottish Centre for Indoor Air - a collaboration between the University of Aberdeen and the Institute of Occupational Medicine - placed the latest smoke monitoring equipment on a child-sized doll in the seat of a car where another passenger was smoking.
The results of the experiment showed that tobacco poison particles inside the car were as high as found in a smoky pub before the smoking ban.
NHSGGC has launched a campaign to persuade motorists who continue to smoke to make their cars tobacco-free.
Brenda Friel, NHSGGC senior health improvement officer, said: "No-one would think twice about the dangers of taking a child into a smoke-filled environment yet many drivers don't realise the harm that can be done.
"We know that second-hand smoke is very harmful but we wanted to understand in more detail the levels of risk attached to second-hand in smoke in cars with particular emphasis on children."
