The authors theorized that the level of exhaled NO could be a marker for bronchiolitis obliterans. Akipinar-Elci studied: (i) 107 workers in the mixing, microwave packaging, and QC areas, which the study classified as a "high-exposure group;" and (ii) 28 workers in the office, packaging, and warehouse area, which the study classified as a "low-exposure group." (33) At the time of the study the diacetyl air concentrations were reportedly: 2.24 ppm in mixing room; 0.426 ppm in packaging; 0.401 in QC; and 0.15 in the office low exposure areas.
