To carry out a prospective combined quantitative analysis of the associations between all cause mortality and ambient particulate matter and sulphur dioxide.
Analysis of time series data on daily number of deaths from all causes and concentrations of sulphur dioxide and particulate matter (measured as black smoke or particles smaller than 10 mum in diameter (PM10)) and potential confounders.
12 European cities in the APHEA project (Air Pollution and Health : a European Approach).
Relative risk of death.
In western European cities it was found that an increase of 50 mug/m3 in sulphur dioxide or black smoke was associated with a 3% (95% confidence interval 2% to 4%) increase in daily mortality and the corresponding figure for PM10 was 2% (1% to 3%). In central eastern European cities the increase in mortality associated with a 50 mug/m3 change in sulphur dioxide was 0.8% (-0.1% to 2.4%) and in black smoke 0.6% (0.1% to 1.1%). Cumulative effects of prolonged (two to four days) exposure to air pollutants resulted in estimates comparable with the one day effects.
The effects of both pollutants were stronger during the summer and were mutually independent.
The internal consistency of the results in western European cities with wide differences in climate and environmental conditions suggest that these associations may be causal. (...)
