We tend to think of poor air quality as affecting our lungs, but what about our other organs?

Air pollution could be one of the factors responsible for cases of adult onset appendicitis, according to new research.

A study at the University of Calgary used regression analysis to compare changes in levels of ozone, nitrogen dioxide, sulfur dioxide, carbon monoxide and particulate matter with appendicitis incidence.

They found that the risk of a person being hospitalized for appendicitis in the city rose by 15 percent on days with the highest ozone concentration, compared with those boasting the lowest concentration. Other air pollution factors were also linked to an elevated risk.

The scientists suggested that air pollution could impact appendicitis by increasing inflammation in the body.

“If the relationship between air pollution and appendicitis is confirmed, then improving air quality may prevent the occurrence of appendicitis in some individuals,” commented lead researcher Dr. Gilaad G. Kaplan.

Meanwhile, a new Swiss study has found that fetuses that are exposed to air pollution may suffer more breathing difficulties when they are born.
