WEBMar 17, 2020 · Ultrafine particles (PM 0.1 ), which are present in the air in large numbers, pose a health risk. They generally enter the body through the lungs but translocate to essentially all organs. Compared to fine particles (PM 2.5 ), they cause more pulmonary inflammation and are retained longer in the lung.
