Title Nasal air sampling for measuring inhaled wheat allergen in bakeries with and without facemask use
Bibliographic information Sep. 2006, Vol.48, No.9, p.948-954. Illus. 25 ref.
Abstract In this study, novel intranasal air samplers (INAS) were used to assess wheat allergen exposure and evaluate respiratory protection in bakeries. Two models of INAS (INAS-M1 and INAS-M2) were compared with the usual method of personal air sampling of inhalable dust (filters mounted in the breathing zone of subjects carrying portable air pumps), both with and without facemasks. Wheat allergen levels were measured using a sandwich immunoassay. Allergenic particles were immuno-stained for microscopic visualization. Personal air sampling correlated well with INAS-M1 and INAS-M2. INAS-M2 collected particles more effectively than INAS-M1. Facemasks reduced inhalation of wheat allergen by 96% and 93% measured using INAS-MI and INAS-M2, respectively. In conclusion, nasal air sampling can complement personal air sampling to measure short-term exposure and evaluate respiratory protection. To prevent baker's asthma, facemasks may be an effective solution in addition to improving workplaces.
