Air Pollution and Daily Death Number

Part II Analysis by Age and Causes

Abstract

The type of excess death pattem consists of 3 types, which are weather type, air pollution type and combined type. Each type was analyzed through the pattern of relationship between changes of atmospheric conditions and daily death number with the lapse of time.
The characteristic difference among these patterns is not clear and it tends to be that the effect of air pollution and temperature to heart disease is immediate and that to respiratory disease or to old persons occurs with time lag.
In the analysis of death number change during the period of smog episode in December 1970, the increase of death by chronic rheumatic heart disease in that period was remarkable.
