Abstract

This report shows that ultrafine air particles (particulate matter or PM) can cause significant health effects in the respiratory, vascular, and cardiac systems, especially in the elderly and those with atherosclerotic vascular disease. The center found that ultrafine particulate matter is easily transported from the respiratory tract to other organs, such as the heart and central nervous system, potentially causing oxidative stress in those organs. Age and disease were found to be critical modifying or susceptibility factors. Researchers also found that impacts on the circulatory system could be worse for those with atherosclerotic vascular disease, such as seen in type 2 diabetes.
