Outline of Final Research Achievements

The outdoor and indoor concentrations of airborne fine (PM2.5) and coarse (PM10-2.5) particulate matter were considerably high in Shenyang and Wuhan, China. In particular, the outdoor concentrations of PM2.5 were high due to coal heating in winter. In this study, no association between exposure to air pollutants and decreases in pulmonary function among children was observed. However, an increase in fractional concentration of exhaled nitric oxide (FeNO) among pre-school children significantly associated with mass concentrations of PM2.5 and PM10-2.5, and the concentrations of carbon and many ions in the particles. The association with FeNO and indoor concentrations of PM2.5 and PM10-2.5 was also significant in May and June. These findings suggest the effect of air pollutants on airway inflammation in children.
