Epidemiologic evidence for an association between black carbon (BC) and health outcomes is limited. We estimated associations and exposure-response relationships between childhood asthma admission and concentration of BC and PM_2.5 (particle less than 2.5 mm in aerodynamic diameter) in ambient air in Shanghai using a lag distributed model. The PM_2.5 and the BC were significantly associated with childhood asthma admissions in single-pollution model. However, the effects of BC on asthma attacks were slightly stronger than those of PM_2.5 after adjusting or not adjusting for NO₂ and SO₂. In conclusion, our study suggests combustion-associated particles are important in China. Black carbon should be considered as one of the air quality indicators in China.
