| Popis: | To evaluate the relationship between exposure to air pollutants and respiratory emergency room visits, a generalized additive model (GAM) was used to analyze the exposure-effect relationship between air pollutants and respiratory emergency room visits. The results showed that NO2, SO2, and PM10 have positive relationships with respiratory disease. Concentration increases of 10 μg/m3 in NO2, SO2, and PM10 corresponded to 3.90% (95%CI 3.56–4.25), 0.81% (95%CI −0.09–1.72), and 0.64% (95%CI 0.55–0.74) increases in respiratory emergency room visits. In addition, there is a strong synergic effect of PM10 and NO2 on respiratory diseases. The threshold values of the national standard grade II limits used in Beijing should be adjusted. An appropriate standard could effectively promote a significant decline in respiratory room visits and would eventually be beneficial to air quality management in residential areas. |
