In many US cities, ozone and particle pollution are the most widespread air pollutants—and among the most dangerous.
According to American Lung Association they aren’t the only serious air pollutants: others include carbon monoxide, lead, nitrogen dioxide, and sulfur dioxide, as well as hundreds of toxic substances.
Recent study has revealed new insights into how they can harm the body—including taking the lives of infants and altering the lungs of children. Below are some interesting findings that supporting strong relation between air quality and human health.
- Reducing air pollution has extended life expectancy. Recent analysis suggested that a drop in particle pollution between 1980 and 2000 has increased life expectancy in 51 U.S. cities increased by 5 months on average
- The annual death toll from particle pollution may be even greater than previously understood. An agency’s estimation of premature deaths in California is tippled from particle pollution to 18,000 annually .
- Long term exposure to air pollution harms women, even while in their 50s. Exposure to particle pollution appears to increase women’s risk of lower lung function, developing chronic obstructive pulmonary disease (COPD), and dying prematurely
- Busy highways are high risk zones. Pollution from heavy highway traffic contributes to higher risks for heart attack, allergies, premature births and the death of infants.
- Ozone pollution can shorten life, a conclusion confirmed by the latest scientific review by the National Research Council. Some segments of the population may face higher risks from dying prematurely because of ozone pollution
- Truck drivers, dockworkers and railroad workers may face higher risk of death. Studies found that these workers who inhaled diesel exhaust on the job were much more likely to die from lung cancer, COPD and heart disease.
- Lower levels of ozone and particle pollution pose bigger threat than previously thought. A study found that low levels of these pollutants increased the risk of hospital treatment for pneumonia and COPD
