The researchers used monitors strapped to the back seat of the car to measure pollution levels
Smoking in the car, even with the windows open or the air conditioning on, creates pollution that exceeds official "safe" limits, scientists say.

Any child sitting in the back of a car when someone in the front is smoking would be exposed to this.

A Scottish team who took measurements during 85 car journeys found readings broke World Health Organization limits, Tobacco Control journal reports.

The British Medical Association says all smoking in cars should be banned.

Currently, it is legal in the UK..

Children are particularly susceptible because they have faster breathing rates, a less developed immune system and are largely unable to escape or avoid exposure to second-hand smoke, says Dr Sean Semple, of the University of Aberdeen.

Using a device strapped to the back seat of the car, the researchers logged and then analysed air quality data during a number of journeys ranging from about 10 minutes to an hour in duration.
