Background  Pooled estimates of air pollution health effects are important drivers of environmental risk communications and political willingness. In China, there is a lack of review studies to provide such estimates for health impact assessments.    Methods  We systematically searched the MEDLINE database using keywords of 80 major Chinese cities in Mainland China, Hong Kong and Taiwan on 30 June 2012, yielding 350 abstracts with 48 non-duplicated reports either in English or Chinese after screening. We pooled the relative risks (RR) per 10 μg/m 3  of particulate matter (PM 10 ), nitrogen dioxide (NO 2 ), sulphur dioxide (SO 2 ) and ozone (O 3 ).    Results  For short-term effects, the pooled RR (p < 0.05) ranges were: 1.0031 (PM 10 ) to 1.0140 (NO 2 ) for all-cause mortality, 1.0034 (cardiopulmonary, PM 10 ) to 1.0235 (influenza and pneumonia, SO 2 ) for 9 specific-causes mortality, 1.0021 (cardiovascular, PM 10 ) to 1.0162 (asthma, O 3 ) for 5 specific-causes hospital admissions. For birth outcomes, the RR (p < 0.05) ranged from 1.0051 (stillbirth, O 3 ) to 1.1189 (preterm-birth, SO 2 ) and for long-term effect on mortality from 1.0150 (respiratory, SO 2 ) to 1.0297 (respiratory, NO 2 ). Publication bias was absent (Egger test: p = 0.326 to 0.624). Annual PM 10  and NO 2  concentrations were inversely associated with RR of mortality (p = 0.017-0.028).    Conclusions  Evidence on short-term effects of air pollution is consistent and sufficient for health impact assessment but that on long-term effects is still insufficient.
