It can cause adverse health effects after inhalation, ingestion, or dermal contact. Exposure to carbon black particles can have adverse effects on the respiratory system; this exposure usually occurs when people inhale contaminated air in the workplace. Here we report a patient with massive carbon black exposure at work who continues to have productive cough with black material in sputum for over a year after this one-time exposure. This patient worked as a repair man and welder at a carbon black manufacturing facility. He had an intense exposure to carbon black for 4 to 10 minutes when equipment in the plant malfunctioned. He developed immediate respiratory symptoms, and these have persisted for at least 1.5 years post exposure with a chronic productive cough with black particles. Cytological analysis of his sputum revealed carbon laden macrophages. A high-resolution computed tomography scan documented patchy alveolar infiltrates at the lung bases with septal thickening. His symptoms have partially improved with empiric treatment with a long-acting beta agonist and inhaled corticosteroids. This case demonstrates that a single one-time exposure to a dense fog of carbon black can result in particle deposition in the lung that persists for prolonged periods of time.<\/jats:p>","DOI":"10.55729\/2000-9666.1434","type":"journal-article","created":{"date-parts":[[2025,1,5]],"date-time":"2025-01-05T04:08:16Z","timestamp":1736050096000},"source":"Crossref","is-referenced-by-count":1,"title":["Massive Carbon Black Inhalation"],"prefix":"10.55729","volume":"15","author":[{"given":"Arunee","family":"Motes","sequence":"first","affiliation":[{"name":"Departments of Internal Medicine, Texas Tech University Health Sciences Center Lubbock, Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tushi","family":"Singh","sequence":"additional","affiliation":[{"name":"Departments of Internal Medicine, Texas Tech University Health Sciences Center Lubbock, Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Irfan","family":"Warraich","sequence":"additional","affiliation":[{"name":"Departments of Pathology, Texas Tech University Health Sciences Center Lubbock, Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenneth","family":"Nugent","sequence":"additional","affiliation":[{"name":"Departments of Internal Medicine, Texas Tech University Health Sciences Center Lubbock, Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"34701","published-online":{"date-parts":[[2025,1,4]]},"container-title":["Journal of Community Hospital Internal Medicine Perspectives"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/scholarlycommons.gbmc.org\/cgi\/viewcontent.cgi?article=1434&amp;context=jchimp","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,5]],"date-time":"2026-09-05T09:56:31Z","timestamp":1788602191000},"score":1,"resource":{"primary":{"URL":"https:\/\/scholarlycommons.gbmc.org\/jchimp\/vol15\/iss1\/16"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,1,4]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2025,1,4]]}},"URL":"https:\/\/doi.org\/10.55729\/2000-9666.1434","relation":{},"ISSN":["2000-9666"],"issn-type":[{"value":"2000-9666","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,1,4]]}}}
