They also looked at air quality data from 617 monitoring stations across 110 Italian provinces to estimate levels of two types of so-called particulate matter: PM2.5, which is smaller than 2.5 micrometers in diameter and can include emissions from burning gasoline, oil, and wood; and PM10, which is 10 micrometers or less in diameter and includes everything in PM2.5 as well as dust from construction, agriculture, landfills, and wildfires.<\/p>\n<p>During the study, 12 percent of the participants were diagnosed with an autoimmune disease.<\/p>\n<p>Higher levels of air pollution exposure increased the odds of this happening. Each additional 10 micrograms per cubic meter (mcg\/m<sup>3<\/sup>) of average PM10 levels was associated with a 7 percent greater autoimmune disease risk.<\/p>\n<aside class=\"ad-wrapper ad-wrapper--audience ad-container inline-widget inline-widget--right-rail _hold-size\"><\/aside>\n<h2><strong>Air Pollution Poses Autoimmune, Cardiovascular, and Pulmonary Threats<\/strong><\/h2>\n<p>\u201cPeople should be aware that being chronically exposed to air pollution can trigger their autoimmune system, as well as being a risk for cardiovascular and pulmonary diseases,\u201d says the lead study author,\u00a0<a target=\"_blank\" href=\"https:\/\/www.researchgate.net\/profile\/Giovanni-Adami-4\" rel=\"noopener\">Giovanni Adami, MD, PhD<\/a>, a rheumatology researcher at the University of Verona in Italy.<\/p>\n<p>\u201cWe have also evidence that acute exposure to high levels of air pollution can aggravate inflammatory <a href=\"https:\/\/www.everydayhealth.com\/rheumatic-diseases\/guide\/\" data-gd-wrapped=\"\">rheumatic diseases<\/a>, such as rheumatoid arthritis,\u201d Dr. Adami says.<\/p>\n<p>Average annual exposure levels of air pollution during the study period were 16 mcg\/m<sup>3<\/sup> for PM2.5 and 25 mcg\/m<sup>3<\/sup> for PM10, the study found.

It\u2019s possible air pollution triggers a reaction in the body that\u2019s supposed to help fight off disease-causing toxins, but misfires and instead causes inflammation and tissue damage that leads to autoimmune disease, Adami says.<\/p>\n<p>Other limitations of the study include a lack of data on the timing of any autoimmune disease diagnoses and the absence of information on the cumulative duration or amount of air pollution exposure for individual participants.
