Low Concentration PM10 Had No Effect on Nasal Symptoms and Flow in Allergic Rhinitis Patients

ABSTRACT

OBJECTIVES: Since Korea is geographically close to China (the origin site for Asian sand dust [ASD]) the health influence of ASD event will be still greater in Korea. We aimed to evaluate the effect of PM₁₀ (particulate matter with aerodynamic diameter 100 μg/m³) RESULTS: There was no significant difference between group A and B in nasal symptoms and PNIF during the 120-day period. Changes in nasal symptoms and PNIF were not statistically significant before or after a PM₁₀ concentration rise above 100 μg/m³. CONCLUSION: Low concentration PM10 does not have significant effect on nasal symptoms and PNIF in AR patients.
