摘要
悬浮颗粒物(Suspended Particulate Matter,以下简称SPM)的环境标准达标率虽然呈增长趋势,但到目前为止达标率依然不很高,日本在1987年只达52.6％,因而确立有效的对策是当务之急。SPM的发生源是多种多样的,不仅有企事业单位的粉尘、汽车排放的尾气,而且还有土壤。
Although the concentration of suspended particulates has met the environmental standard at an increasing rate, the percentage of particulates that have reached the standard is not high for the time being. It was only 52.6％ in Japan in 1987. Therefore, it is urgent to take effective measures. Suspended particulates have many unique characteristics in polluting the environment. This paper, on the basis of investigation results made by the Environmental Protection Agency of Japan, introduces briefly the state of suspended particulate pollution and its problems and control strategies.
