Air pollution is known to cause many detrimental effects on the human body. According to a new report, air pollution may increase the risk for appendicitis. Researchers studied 35,811 patients hospitalized for appendicitis in 12 Canadian cities between 2004 and 2008.High ozone levels were associated with an increased number of hospitalizations for appendicitis and were even more strongly associated with cases of burst appendix. For each 16 parts per billion increase in ozone concentration the scientists found an 11 to 22 percent increase in ruptured appendix cases.
