Roughly one-third of the US population may be at an increased risk of developing health problems resulting from exposure to polluted air containing fine particulates. The tiny size of these pollutants allows them to travel deep into the lungs or other organs, potentially causing damage. In a new study, the specific effects of exposure to fine particulates on occurrence of inflammation, insulin resistance and obesity has been examined. These conditions are not only harmful themselves but are also risk factors for the development of type 2 diabetes.
