Ozone air pollution and daily mortality in Genoa, Italy between 1993 and 1996.

This study assessed the effect of O3 concentration on daily mortality in an Italian city with a high proportion of elderly residents and a sizeable presence of oxidative photochemical air pollutants. Despite the short study period and the small population, a statistically significant association between O3 and daily mortality was detected for all-cause mortality and CV mortality. This effect was particularly evident at lag 1 during the warm period.
