大阪地区大气污染物质的测定及分析

Determining and Analyzing Air Pollution Materials in Osaka Area

大阪地区的大气污染主要为汽车尾气型,同时受地貌及气候影响,这些污染会发生各种质或量的变化。通过在大阪地区连续测定同一方向上不同地点的污染浓度,可以看出大阪地区的大气污染从西向东的变化关系。同时随着空气的流动,城市的大气污染也影响到无污染发生源的高山地区。

The atmospheric pollution in Osaka area is mainly from automobile tail gases. The quantity and quality of the pollution will be changed because of climatic and geomorphic changes. When continuously monitoring pollution at different points in the same direction in Osaka area, two conclusions were drawn: 1. The air pollution moves from west to east and 2. With air flowing, the urban air pollution also influences the area where no pollution source exists.
