Summary:
Short-term exposure to ozone (O3) has been associated with health effects, such
as increased daily mortality especially on warmer days of the year. Previous
studies that examined the effects of O3 on mortality have focused on daily
number of deaths and applied time series techniques. The purpose of the present
dissertation is the application of an index based on years of life lost as a
supplementary indicator to assess the effects of O3, that is more informative
in terms of HIA as it accounts for life expectancy at the age of death. We
collected mortality and pollution time series data for Athens, Greece during
the period 2001-2011.

We found that was associated with an increase in the number of years of life
lost after prolonged exposure (lags 0-6). The increase in years of life lost
associated with 10 μg/m3 increase in O3 due to late effect for total period of
the year was 6.58 years (95% CI: 2.40, 10.76), while during the warm period the
corresponding figure was 10.63 years (95% CI: 3.81, 17.47 ). The effects are
probably attributed to delayed effects of the previous 2-6 days exposure.
Finally, the effects of exposure to O3 in both the daily number of deaths and
the years of life lost differed between younger and older ages (<75 or 75
years).

Our findings support the existence of aggravating effects of short-term
exposure to O3 on mortality in Athens, especially after prolonged exposure and
among people <75years. The number of years of life lost may be used as a
supplementary indicator for evaluation of O3 effects. In conclusion, stricter
measures are recommended to reduce O3 concentrations especially during the
warmer period for optimal protection of public health.
