New research found a significant link between outdoor air pollution and diabetes.
Overall, the researchers estimated that pollution contributed to 3.2 million new diabetes cases globally in 2016, which represents about 14 percent of all new diabetes cases globally that year.
In the United States, the study attributed 150,000 new cases of diabetes per year to air pollution…
In the U.S., the EPA’s pollution threshold is 12 micrograms per cubic meter of air, …
… using mathematical models, Al-Aly’s team established an increased diabetes risk at 2.4 micrograms per cubic meter of air. Based on VA data, among a sample of veterans exposed to pollution at a level of between 5 to 10 micrograms per cubic meter of air, about 21 percent developed diabetes. When that exposure increases to 11.9 to 13.6 micrograms per cubic meter of air, about 24 percent of the group developed diabetes.
… the researchers looked at particulate matter, airborne microscopic pieces of dust, dirt, smoke, soot and liquid droplets. Previous studies have found that such particles can enter the lungs and invade the bloodstream, contributing to major health conditions such as heart disease, stroke, cancer and kidney disease. In diabetes, pollution is thought to reduce insulin production and trigger inflammation… [emphasis mine]
