Abstract

Background: Exposure to air pollution is associated with a short-term increase in mortality, and this field has begun to focus on health impact assessment.

Objectives: Our aim was to estimate the impact of PM10on mortality within 2 days from the exposure in the Italian region of Lombardy for the year 2007, at the municipality level, examining exposure entailed by daily intermunicipality commuting and accounting for uncertainty propagation.

Methods: We combined data from different sources to derive probabilistic distributions for all input quantities used to calculate attributable deaths (mortality rates, PM10concentrations, esti-mated PM10 effects, and commuting flows) and applied a Monte Carlo procedure to propagate uncertainty and sample the distribution of attributable deaths for each municipality.

Results: We estimated that annual average PM10concentrations above the World Health Organization-recommended threshold of 20 μg/m3 were responsible for 865 short-term deaths (80% credibility interval: 475, 1,401), 26% of which were attributable to PM10above the European Union limit of 40 μg/m3. Reducing annual average PM10concentrations > 20 μg/m3by 20% would have reduced the number of attributable deaths by 36%. The largest estimated impacts were along the basin of the Po River and in the largest cities. Commuting contributed to the spatial distribution of the estimated impact.

Conclusions: Our estimates, which incorporated uncertainty quantification, indicate that the short-term impact of PM10on mortality in Lombardy in 2007 was notable, and that reduction in air pollution would have had a substantial beneficial effect on population health. Using commuting data helped to identify critical areas for prioritizing intervention.
