Young people in cities have billions of air pollution particles in their hearts, a new study has found.
In one shocking case, a three-year-old had small toxins in the cells of the organ that had damaged his pump muscles.
The slowdown in traffic – and in industry – in British cities can be the cause of high levels of civilized heart disease in the world, according to scientists, who can pose a serious public health problem.

Although there were doubts about the research, it is the first direct evidence that air pollution particles can be linked to heart disease.
And the iron-rich non-particles could even mess with the electrical signals that pump the heart.
The new study showed that scientists take heart tissue from 63 people – with an average age of 25 – who lived in the highly polluted city of Mexico.
The test subjects died in traffic accidents but had no injury to their chest.
Researchers first looked at the amount of iron-rich nanoparticles in the body, then at the place where they were found and at what damage they had caused to the tissue.
The 63 cases drew totals of between 2 billion and 22 billion particles per gram of dried tissue.
The subjects for the study died in traffic accidents, but had no injuries to their chest. In the photo: a woman with a face mask against dangerously high levels of smoke pollution while she crosses the street in Mexico City in May
Tests were performed on nine other people who were not living in Mexico City, which showed that they had between two and ten times fewer particles in their tissue.
The team said that & # 39; exposure to (nanoparticles) appears to be directly related to early and significant heart damage & # 39 ;, adding to Prof Maher that it could be the same in other cities.
Professor Barbara Maher, from the University of Lancaster, told it Guardian: & # 39; This is a preliminary study in a way, but the findings and implications were too important not to get the information there. & # 39;
The scientists, whose research was published in the journal Environmental Research, discovered that people of all ages could suffer from air pollution, but Prof Maher added: “For really young people, the evidence is now of very early stage damage, both in the heart and the brain. & # 39;

It was already clear that air pollution particles from roads could damage the body.
Matter enters the energy-producing mitochondria, which affect the way the heart pumps blood around the body.
The findings come three years after Prof. Maher and other university scientists found traces of the same nanoparticles in people's brains – which they said caused damage similar to that of Alzheimer's.
And another study recently found that particles of air pollution can have a negative impact on any human cell because they are inhaled and move through the blood.

Because it is unethical to experiment on humans, the evidence used in these studies is epidemiological, but last year harmful matter was found in the placenta of women after delivery.
Mark Miller, an expert from the University of Edinburgh, who studies the effect of air pollution on the cardiovascular system, said: “More effort is needed to reduce vehicle particle emissions, especially to reduce the number of vehicles on the road reduce by encouraging people to walk and cycle for short journeys. & # 39;

The particles found came from condensation of burning fuel, which cooled to form spheres.
These were found in the heart tissues of the patients studied and differed from other small iron-rich magnetic crystals that can normally be found in the brain.
Using the technology used, the scientists were able to find the particles, but could not assess their formation.
For this they had to split the tissue and the particles, using the average size and how magnetic they would be to a total figure.
The team wants a definitive answer for how many particles are in the cells, but do not have the budget for the expensive equipment that is needed.
The study has an increased sense of fear of the threat caused by road traffic particles.
Four million children worldwide develop asthma, an estimated large study.
Exposure to nitrogen dioxide, largely from road transport, is thought to be behind 38,000 new cases in the UK and 240,000 in the US per year.
The global study, reported in April, ranked the UK 29th in the worst of the 194 countries for the number of children who develop asthma due to traffic pollution.
The global survey ranked the United Kingdom as the 29th worst out of 194 countries for the number of children who develop asthma due to traffic pollution. The US placed 22nd while Australia turned 64, according to the study published in a prestigious medical journal
The road outside Earl & # 39; s Court Underground Station in Kensington, London, is the most polluted in the country, according to the Friends of the Earth survey
Charities have warned that the findings provide even more evidence that toxic fumes present tens of thousands of children with the risk of potentially fatal asthma attacks.
Researchers have found that 19 percent of asthma cases among young people (from one to 18 years old) in the UK and the US can be attributed to nitrogen dioxide pollution.
This rose to nearly a third in London (29 percent) where the pollution rate is highest, according to the study published in The Lancet Planetary Health.
In the UK there were around 280 new cases per 100,000 children per year – compared to 550 in Kuwait, who scored the worst.
Dr Samantha Walker, of Asthma UK, said: “Worryingly, this study confirms existing research showing that children who breathe toxic air through traffic gasses hamper lung growth and risk developing asthma.”
