Title Effect of respirators equipped with particle or particle-and-gas filters during exposure in a pig confinement building
Bibliographic information Apr. 2006, Vol.32, No.2, p.145-153. Illus. 33 ref.
Abstract This study compared the protective effect of two respiratory protection devices during exposure in a pig confinement building. Thirty-six healthy workers were exposed for three hours in the building, 12 without any protection, 12 with a particle-filter mask and 12 with a mask filtering both particles and gases. Symptoms, body temperature, nasal lavage fluid, exhaled nitric oxide and bronchial responsiveness to methacholine were assessed before and after the exposure. Pre- and post-exposure urine and blood samples were collected. Findings indicate that wearing a respirator in a pig confinement building reduces the inflammatory reaction but does not influence bronchial responsiveness. There was no difference between the use of a particle-filter mask and a mask with a particle-gas filter combination.
