    Abstract:
    Simultaneous evolution of daily data collected in Paris (1969-1976) concerning mortality on the one hand, and pollution and meteorology on the other hand, is described during two specific episodes: the first, observed in december 1969, is a high mortality one, due to an influenza epidemic; the other, observed in december 72-january 73, is related to high pollution levels. Mortality data are specified using daily-rate of death, according to diagnosis and age-range. Chosen pollutants are acidity and smoke. Meteorological conditions are identified by synoptic data and local parameters (pressure, temperature and humidity). Among results, it is shown for example that the mortality-excess is mainly due to respiratory diseases, that it concerns elderly persons when heavy pollution, but younger persons (less than 75 years old) when influenza epidemic; pollution effects are not detected when daily acidity level is less than 300 micrograms/m3 but they systematically appear for level more than 400 micrograms/m3. "Compensation" effects (mortality-rate decrease occurring after high mortality days) have been pointed out. Tentative interpretation is proposed, including also temperature and humidity effects, and validation is necessary to do.
