Researchers have identified a chemical agent that may be a, if not the, culprit in bronchiolitis obliterans syndrome (BOS), or "popcorn worker's lung," a severe occupational lung disease first noted in 2001 among workers at an American plant that makes microwaveable popcorn. The research examined a population of workers at a chemical plant that produced diacetyl (a key component of butter flavoring). While the researchers were unable to rule out contributions of other chemicals to the development of BOS, the study significantly narrows the field of suspects to diacetyl and the components and byproducts of its manufacturing process.
