It’s not the fumes of gasoline that kill you, but the chemicals in the atmosphere that cause it, according to a new study published in the American Journal of Public Health.
A team led by the University of California, Berkeley’s Peter S. Hsieh analyzed data from more than 40 studies that included air pollution and air quality data.
They found that, overall, air pollution is the leading cause of air-related deaths.
And, the researchers found, the chemicals found in the polluted air were the most common contributing factor.
But what makes the findings so alarming is that the study also found that there is something else that’s contributing to the problem.
The researchers say that in some cases, the air pollution itself may be the culprit.
The team found that people who breathed the polluted, smoky air, were more likely to develop a lung disease and to develop chronic obstructive pulmonary disease.
And their numbers showed that this is the case in people who live in areas with very high concentrations of sulfur dioxide.
Sulfur dioxide is the main ingredient in gasoline, and it can also be found in water and coal.
So the team hypothesized that sulfur dioxide could play a role in causing the problem of air pollution.
The study, which has not yet been peer-reviewed, suggests that it could be the combined effect of several toxic compounds, including the sulfur compounds in sulfur dioxide, the CO2 in coal and the ozone in the sky.
The authors said they didn’t have any data on other substances, such as nitrates or particulates, which they say could be responsible.
Samples of air samples were taken in several cities around the world.
Researchers analyzed data taken from people’s lungs, blood, urine and blood samples.
They also looked at air samples from other parts of the world, and air samples taken at various times of day.
To investigate the relationship between air pollution levels and lung cancer, the team took samples of lung tissue from people in New York, Los Angeles, Miami, Boston, Miami Beach, and New Orleans.
They then used a computer model to model how the pollution would impact the people’s lung tissue.
The researchers found that the people in the highest pollution areas had higher levels of carbon monoxide in their lungs than people in lower pollution areas.
And they had higher concentrations of nitrates in their blood than people who lived in areas of moderate pollution.
When they looked at other parts, they found that in areas where pollution levels were high, people had higher rates of lung cancer than people living in areas that were relatively peaceful.
The scientists also looked for changes in the human immune system in the people living near pollution areas, and they found the people who were exposed to higher levels had more antibodies that reacted to the pollutant and would help the immune system fight it off.
The findings are just the latest to link air pollution to cancer.
In January, a study published by the British Medical Journal found that air pollution was the single most important cause of lung disease in the United Kingdom.
A study published last year in the journal Environmental Science & Technology found that a higher level of pollution in China was linked to lung cancer rates that were more than three times the U.S. rate.
