The article presents a study of the use of exhaled breath condensate (EBC) to investigate occupational lung diseases, published in this journal by Corradi et al. In the Medline index, the respective literature was scanned, evaluated by PubMed using keywords, including “respiration AND condensation AND occupational.” Between January 2018 and October 2019, eleven relevant publications were recovered. The only article concerned employment allergy is that the hydrogen peroxide in EBC is not a useful predictor of animal allergy. Metals are the most often evaluated biomarkers of toxicity. Although whether this technique is advantageous compared to traditional environmental surveillance is questionable. In most of the research, the biomarkers of impact examined were oxidative stress-related. They tend to be continuously elevated after industrial exposure to a variety of agents such as welding smoke, crystalline silica, nanomaterials, and chemicals.

While the EBC is the appropriate instrument for noninvasive sampling of airway fluid filling, the solution to occupational diseases continues to be a niche approach. In expression of the data, the confusing impact of EBC dilution should be best handled.
