By now, if you are a pedestrian or cyclist you are probably aware that traffic pollution is a danger to your health, but there is one group of people who are perhaps more at risk: children in cars.

Numerous studies have shown how high pollution levels are in cars. A study in Copenhagen found that a driver actually breathed in higher amounts of pollution than a cyclist on the same road. For the cyclist, the emissions dissipated into the wider atmosphere which reduced their exposure, but for the car driver these emissions were circulated and built up in the cabin.

The government’s latest estimates suggest that 80% of harmful pollution at the roadside in the UK is coming from cars, vans and buses. This pollution is hugely damaging for our health – tiny particles and poisonous gases are able to travel deep into our lungs and recent studies have shown they can get into our bloodstream.

For children whose lungs are still developing, these emissions are even more dangerous. They can stunt the growth of their lungs and leave them with permanent lung damage.

On average, we spend about 1.5 hours a day in our cars. What many drivers probably don’t realise is these fumes can be just as high in the car as outside, and in some cases even higher.

The oldest cars are the most polluting, particularly diesel vehicles. Children sitting in the back seat are likely to be exposed to dangerous levels. You may be driving a cleaner vehicle but still be collecting toxic gases from all the vehicles around you.

In recent years, we have taken major steps to protect children from breathing in secondhand smoke in cars. Alongside the British Lung Foundation, parents across the UK demanded the government bring in new legislation to ban smoking in cars with children. In a 2014 survey nearly 80% of adults and 64% of smokers supported the ban and MPs overwhelmingly voted for it. So why are we still happy for our children to breathe in toxic emissions in the back of our cars?

While it might feel like you can wind up your windows and seal yourself into the safety of your car, that is far from the case. Cars have a constant through-flow of air even with all the windows shut. Air enters through a large duct at the front and is forced through the car. In heavy traffic, this duct would be sucking up the polluted air from the car in front. Of course, the amounts differ depending on the make and model of the car.

But one thing is for sure, being in your car does not make you or your children immune to the deadly effects of air pollution. The best thing for all our health is to leave our cars behind. It’s been shown that the health benefits of walking and cycling far outweigh the costs of breathing in pollution.

During Breathe Easy Week from 12 to 16 June, the British Lung Foundation’s support groups all over the UK will be campaigning for cleaner air. The next government urgently needs to make cleaner alternatives – hybrids, electric vehicles, walking and cycling – the easiest and cheapest options for us all.

By bringing in a targeted diesel scrappage scheme they could help many more people make greener and healthier choices. They should also run a public awareness campaign that makes sure we all know when and how pollution is impacting our health. If more drivers knew the damage they could be doing to their children, I think they’d think twice about getting in the car.

Prof Sir David King is chief scientific adviser to the UK government and honorary science adviser for the British Lung Foundation.

Air pollution more harmful to children in cars than outside, warns top scientist


Children are at risk of dangerous levels of air pollution in cars because exposure to toxic air is often far higher inside than outside vehicles, a former government chief scientific adviser has warned.

Prof Sir David King, writing for the Guardian, says walking or cycling to school would be much better for children’s health. The warning comes as the UK government faces a third legal defeat for failing to tackle the country’s illegal levels of air pollution. Air pollution is known to damage children’s developing lungs but recent research also indicates it harms children’s ability to learn at school and may damage their DNA.

“Children sitting in the backseat of vehicles are likely to be exposed to dangerous levels [of air pollution],” said King. “You may be driving a cleaner vehicle but your children are sitting in a box collecting toxic gases from all the vehicles around you.”

He said new legislation to ban smoking in cars with children had gained widespread support. “So why are we still happy for our children to breathe in toxic emissions in the back of our cars?”

“The best thing for all our health is to leave our cars behind,” said King, who now advises the British Lung Foundation. “It’s been shown that the health benefits of walking and cycling far outweigh the costs of breathing in pollution. If more drivers knew the damage they could be doing to their children, I think they’d think twice about getting in the car.”

A range of experiments, some as far back as 2001, have shown that drivers inside vehicles are exposed to far higher levels of air pollution than those walking or cycling along the same urban routes.

Prof Stephen Holgate, an asthma expert at Southampton University and chair of the Royal College of Physicians working party on air pollution, said there was enough evidence to tell parents that walking and cycling exposes their children to less air pollution than driving.

“It is nine to 12 times higher inside the car than outside,” he said. “Children are in the back of the car and often the car has the fans on, just sucking the fresh exhaust coming out of the car or lorry in front of them straight into the back of the car.”

Children are more vulnerable than adults, he said, because air pollution can stunt the growing of their lungs and because it increases the risk of sensitisation which can lead to asthma and other respiratory conditions.

Holgate said walking or cycling are better when possible, to reduce pollution exposure in cars and to increase physical exercise. He said: “There are multiple benefits to be gained. But parents are confused at the moment because they think there is less pollution in cars than outside, which is not the case.”

Ben Barratt, from King’s College London, measured the exposure of people travelling by car, bus, bicycle and walking in London in 2014. “The car driver, by a very long way, was exposed to the highest level of pollution,” he said. “The fumes from the vehicles in front and behind were coming into the car and getting trapped there. It is not true that you can escape pollution by sitting inside a vehicle.”

Recent research has added to the concern about the impact of air pollution on children, beyond the direct harm to their lungs. A study in Barcelona showed that air pollution reduces the ability of children to concentrate and slows their reaction times. “This adds to the evidence that air pollution may have potential harmful effects on neurodevelopment,” the scientists wrote.

A smaller study, in California, showed higher levels of traffic-related air pollution correlated with increased DNA damage in children.” Children may be especially vulnerable to the effects of telomeric DNA damage due to their physical development as well as developing immune system,” said the scientists.

Levels of nitrogen dioxide (NO2), emitted mostly by diesel vehicles, have been above legal limits in almost 90% of urban areas in the UK since 2010. The toxic fumes are estimated to cause 23,500 early deaths a year and the problem has been called a public health emergency by a cross-party committee of MPs.

The environmental law firm ClientEarth has defeated the ministers twice in the courts over the adequacy of government air quality plans. Ministers’ latest proposals were published on 5 May but were widely condemned as inadequate, and ClientEarth is now suing the government a third time.

“Air pollution hasn’t been taken seriously,” said Holgate. “There is a very strange situation where the government has to make laws by being taken to court repeatedly. In my view it is really quite appalling that we haven’t started to deal with this properly and put children’s and adults’ health first.”

Diesel drivers have been given tax breaks by successive governments, including when King was chief scientific adviser, to buy diesel cars because they have lower carbon dioxide emissions. Stricter regulations were supposed to limit NO2 emissions from diesels but cheating and the exploitation of loopholes by car manufacturers led to vehicles that emitted far more pollution on the road than in lab tests.

The British Lung Foundation’s Breathe Easy Week takes place on 12-16 June 2017 and a National Clean Air day in the UK takes place on 15 June.

• The Surgeon General has determined that there is no safe level of exposure to ambient smoke!

• If you smell even a subtle odor of smoke, you are being exposed to poisonous and carcinogenic chemical compounds!

• Even a brief exposure to smoke raises blood pressure, (no matter what your state of health) and can cause blood clotting, stroke, or heart attack in vulnerable people. Even children experience elevated blood pressure when exposed to smoke!

• Since smoke drastically weakens the lungs' immune system, avoiding smoke is one of the best ways to prevent colds, flu, bronchitis, or risk of an even more serious respiratory illness, such as pneumonia or tuberculosis! Does your child have the flu? Chances are they have been exposed to ambient smoke!
