Abstract

The association between acute exposure to SO2 and mortality was studied using historical data from 1972–1991 in Yokkaichi, Japan, via a time-stratified case-crossover study design. All causes of death, excluding external causes, between 1972 and 1991 in Yokkaichi and the neighboring town, Kusu of the Mie Prefecture (N = 29,839) were included. Daily estimations of SO2 concentrations were obtained during the study period. Conditional logistic regression analysis was carried out to assess the association between SO2 exposure and all-cause and cause-specific mortality. Data revealted that exposure to SO2 increased the risk of all-cause and cause-specific mortality in a non-linear manner. The relationship between SO2 exposure and mortality outcomes remained after adjustment for co-pollutants such as particulate matter and NO2. Historical data from Yokkaichi, Japan, showed that SO2 exposure increased the risk of all-cause and cause-specific mortality.
