Abstract
The paper presents results from the statistical description of total daily mortality dependence on ambient air temperature in the Chisinau
municipality. Total daily deaths, taken from death certificates, characterize mortality in the period of April 1 to September 30 for the years 2000-
2008. Mean (Tmean), maximal (Tmax) and minimal (Tmin) temperatures were used as independent variables. The extremely hot “warm season”
of 2007 was excluded from the study. Pertinent statistical procedures were used to describe the statistical dependencies. The thermal optimum
(minimal mortality temperature, MMT) was defined as a 2°C temperature band. It was shown that minimal daily mortality was observed at
Tmean about 220C. In the first half of the period, each 1°C increase of Tmean is accompanied by a 1.43%-decrease in daily mortality. Analogous
analysis for Tmax and Tmin identified corresponding MMTs as 27-28°C and 17-18°C, and decreases in deaths as 1.41% and 1.47%, respectively.
In August-September, air temperature decrease determines, depending on the temperature variable used, between 19.3% and 23.9% of total
mortality, and each 1°C decrease of Tmean, Tmax and Tmin causes respectively 0.64%, 0.61% and 0.80% increase of mortality.
