Small changes due to air pollution in our bodies

One study in Canada using volunteers to breathe dirty air are found in many large cities, to see who made the poison to our genes.
For two hours inhaling diesel fumes in the basement of a hospital is not a pleasant thing in the morning.
But that is what Julia, subject COPA-03, inside a soundproof chamber measuring 1.2 x 1.8 meters with a height of 2.1 meters while watching Netflix on the iPad.
Sometimes he uses a bike trainer to regulate breathing. The amount of smoke inhaled diesel which is roughly equivalent to the level of air pollution in Mexico City or Beijing.
His job is not to promote tourism in the cities polluted it.
But in a soundproof room, he was helping to better determine the impact of air pollution, giving a clue to the continued need in cleaning up the air we breathe, and focus on breathing problems in people who suffer the most.

Air pollution has recently become a big concern: in 2014, the German car industry, Volkswagen, hit by a major scandal after it was revealed they put up 'the fraudsters' in his car to be able to look 'cleaner' while doing the emissions test.
In 2030, the Board of the World Organisation, WHO, estimates that Chronic Obstructive Pulmonary Disease, COPD, or Chronic Lung Disease Disorders is the third leading cause of premature death worldwide.
His condition is usually associated with smoking (but not always), and research shows that in the case of non-smokers, air pollution, including diesel fumes may be the cause.
The 'inherent' in developing countries
In London alone, poor air quality is expected to kill about 10,000 people each year, even in times of extreme incidents such as the so-called Big Smoke 1952, the mortality rate is usually much higher.
Diesel smoke is a pollutant that always exist in developing countries, said Dr. Jeremy Hirota, University of British Columbia, Canada. In these countries, it is not unusual to see black smoke out of the truck. The black soot is solar particles.
We go back to Julia, who inhale the smoke through the pipes of diesel engine generator whined outside Vancouver General Hospital.
The smoke is channeled into the room where she was and diluted with clean filtered air. After two hours of sucking in a controlled manner, Julia was taken by taxi to the hospital St Paul, where he occasionally regularly use a bicycle trainer.
There, in a room that is smaller sized public phone box with a glass-wall guides the technician Julia to attract and exhale firmly into a tube.
Lung function is described in a series of charts and Julia examined for changes in the blood, urine, and lung function.
This is not a job for wimps volunteers. Then, a respiratory expert, Dr. Chris Carlsten, put a tube in the throat Julia were drugged, spraying salt into the lungs and suck part of the lining of the lung are separated by using a brush.
This experiment is very valuable. By making each of volunteers exposed to a mixture that is set from the air cleaner or air polluted by diesel at random, then the volunteers did not know him breathe air that is dirty or clean.
Thus Carlsten and Hirota -two professor of medicine at the Center for Chronic Disease Lung Disorders University of British Columbia- can examine how pollution particles affect us.
Carlsten previous research indicates that while only two hours of exposure to air pollution can affect our genes. Influence is not a change on the DNA sequence -a kind of 'menu; which makes indvidu unik- however, air pollution seems to add chemicals to the DNA sequence.
