Ambient fine particulate matter (PM) has been associated with impaired lung function, but the effect of temperature on function and potential interaction between PM remain uncertain. To estimate short-term effects PM2.5 combined we measured daily peak expiratory flow (PEF) in a panel 37 healthy college students four different seasons. Meanwhile, also monitored concentrations indoor outdoor (particulate an aerodynamic diameter ≤2.5 μm), ambient relative humidity study area, where participants lived attended school. Associations air pollutants were assessed by generalized estimating equations (GEEs). A 10 μg/m3 increase was change −2.09 L/min evening PEF (95%CI: −3.73 L/min–−0.51 L/min) after adjusting for season, height, gender, humidity. The changes −2.17 −3.81 L/min– −0.52 −2.18 −3.96 L/min–−0.41 observed SO2 NO2 Environmental Monitoring Center 3 kilometers away, respectively. An found to be decrease our results revealed small significant antagonistic interactive temperature. Our findings suggest that acute adverse young adults, plays important role.
