%X Little evidence is available on the strength of the association between ambient air pollution exposure and health effects in developing countries such as South Africa. The association between the 24-h average ambient PM 10, SO 2 and NO 2 levels and daily respiratory (RD), cardiovascular (CVD) and cerebrovascular (CBD) mortality in Cape Town (2001¨C2006) was investigated with a case-crossover design. For models that included entire year data, an inter-quartile range (IQR) increase in PM 10 (12 mg/m 3) and NO 2 (12 mg/m 3) significantly increased CBD mortality by 4% and 8%, respectively. A significant increase of 3% in CVD mortality was observed per IQR increase in NO 2 and SO 2 (8 mg/m 3). In the warm period, PM 10 was significantly associated with RD and CVD mortality. NO 2 had significant associations with CBD, RD and CVD mortality, whilst SO 2 was associated with CVD mortality. None of the pollutants were associated with any of the three outcomes in the cold period. Susceptible groups depended on the cause-specific mortality and air pollutant. There is significant RD, CVD and CBD mortality risk associated with ambient air pollution exposure in South Africa, higher than reported in developed countries.
