The relationship between air pollution and weather as stimuli and daily mortality as responses in Tokyo, Japan, with comparisons with other cities

Abstract

A comparative, stimulus-response analysis of 3 yr of Tokyo daily mortality in relationship to air pollution and weather, has yielded significant relationships between abnormal environmental events (stimuli) and subsequent high (excess) mortality events (responses). The relationships between the magnitudes of these events and the nature of these events are similar to those found in New York. One can therefore generalize relationships between mortality and air pollution-weather over the many subsets of different environmental situations and mortality experiences.
