Reference Population Exposure Results
Broeckaert et al 2000
(222)
Cyclists In quartiles mean
48,72, 89 and 96
ppb
Significant elevations in CC-16 protein measured in Clara cells for those exposed to 3rd and 4th quartile
Holz et al
2002 (224)
Allergic asthmatics   Enhanced functional and inflamatory bronchial response to inhaled allergen challenge
Frampton et al 1995
(214)
Healthy and allergic asthmatic nonsmokers 3 hours to 80, 120 and 160 ppb after exposure to H2SO4 and NaCl Small, significant reductions in FVC, FEV in the highest exposure group, greater for those exposed to H2SO4 and bigger for asthmatics
Frank et al
2001 (223)
Young adults 0.25 ppm for 2h over 4 days Spirometric values show adaptation, persistent small airway dysfunction/resistance
Devlin et al
1997 (215)
Young male adults Repetitive exposures 0.4ppm for 2h over 5 days Inflammatory mediators are attenuated, some do not return to normal after 20 days upon O3 challenge. Several markers of cell injury are not attenuated
