An Assessment on Effect of PM10 Concentration on Premature Mortality Rate in Nagoya, Japan

Abstract

Effect of PM 10 concentrations on premature mortality rate was investigated for Nagoya, Japan by using 9years data from 1996 to 2004. Multiple regression analysis was performed. As a result, average age of the residents, temperature, and PM10 concentration were identified as important parameters explaining premature mortality rate, while NO₂ concentration was not. Based on the multiple regression model which obtained in this study, that about 17 prematuredeaths per 100, 000 people per one year would be avoided was predicted for a reduction of annually averaged PM10 concentration by 10 μgm^-3, which was qualitatively consistent with an other approach by Ostro (1994).
