摘要

The evidence is quite limited regarding the constituents of fine particilate matter (PM_(2.5)) responsible for lung dysfunction. We designed a time-series panel study in 28 patients to examine the effects of 10 major constituents of PM_(2.5) on lung function with repeated daily measurements from December 2012 to May 2013 in Shanghai, China. We applied a linear mixed-effect model combined with a distributed lag model to estimate the cumulative efiects of PM_(2.5) constituents on morning/evening forced expiratory volume in 1-s (FEV_1) and peak expiratory flow (PEF) over a week. The cumulative decreases in morning FEV_1, evening FEV_1, morning P£F and evening PEF associated with an interquartile range (35.8 µg/m~3) increase in PM_(2.5) concentrations were 33.49 [95% confidence interval-(CI):2.4S,54.S3] mL, 16.80 (95%CI:3.75,29.86) mL, 4.48 (95%CI:2.30,6.66) L/ min, and 1.31 (95%CI:-0.85,3.47) L/min, respectively. These results were not substantially changed after adjusting for gases in two-pollutant models. The associations of elemental carbon (EC) and nitrates with morning/evening FEV_1, and the associations of EC and sulfates with morning PEF were robust after controlling for PM_(2.5). This study demonstrated that short-term exposure to PM_(2.5) was associated with reduced pulmonary function. Some constituents (EC, sulfate and nitrate) may be responsible for the detrimental effects.
