Using microscopy, the team measured carbon deposits in alveolar macrophages\u2014cells responsible for clearing harmful particles from the lungs. They found COPD patients had&nbsp;<strong>three times more carbon<\/strong>&nbsp;in these cells compared to smokers, with larger deposits linked to worse lung function.<\/p>\n\n\n\n<p>Lab experiments revealed that carbon-exposed macrophages grew in size and produced higher levels of inflammatory proteins. Dr. Lea noted,&nbsp;<em>&#8220;This buildup isn\u2019t just from smoking.
