  1. Air pollution and mortality in Madrid, Spain : a time-series analysis.

    Article - En anglais

    Objective 

    To assess the relationship, if any, between air pollutant (sulfur dioxide and total suspended particulate) levels and mortality in the city of Madrid during the period 1986-1992, controlling for weather, season, and influenza epidemics.

    Methods 

    Daily death counts were obtained from the Regional Mortality Registry.

    Pollution data were supplied by the Municipal Monitoring Network.

    Time-series analysis methodology was used to assess the link between non-accidental as well as circulatory-and respiratory-disease mortality, on the one hand, and mean daily concentrations of SO2 and total suspended particulate (TSP), on the other.

    Multivariate autoregressive integrated moving-average (ARIMA) models were used to adjust for season, temperature, relative humidity, and influenza.

    A sensitivity analysis was run to assess the robustness of the estimators.

    Results 

    Graphical analysis revealed a linear relationship between mortality and TSP.

    The relationship was logarithmic in the case of SO2.

    TSP lagged I day and SO2 lagged 3 days with an independent effect on mortality.

    This relationship was produced without the detection of a minimal threshold in emission values.

    Conclusions 

    These results support the hypothesis of an association between pollution levels and mortality between 1986-1992 in Madrid.

    Additional measures designed to reduce pollution levels without compromising thermal comfort should be implemented.
