广州地区室内外空气污染的比较研究

对广州市四个区及农村县从化室内外空气中的四种主要污染物浓度进行比较，结果显示：城市空气污染物SO2，BaP，及TSP的浓度为室内高于室外（P＜0．05），N仇则为室外高于室内。农村四种污染物均为室内大于室外（P＜0．01）。对同一地点室内外空气污染物作相关分析发现，室内外空气污染物浓度呈正相关（r＝0．82，P＜0．01）。由于人的一生2／3的时间是在室内度过的，室内空气污染对人体的远期危害应大于室外空气污染。

Comparison of Indoor Air Pollution with outdoor Air Pollution in Guangzhou

To compare indoor air pollution with outdoor air pollution, concentrations of SO2, NOx, TSP andBaP were measured both indoors and outdoors in the city of Guagnzhou and the countryside of Conghua.The results showed that the conentrations of all four pollutants were higher in Guangzhou than in thecountryside (p <0.01) both indoors and outdoors and were higher in indoors than in outdoors (P < 0.05)except the concentration of NOx in Guangzhou. There was a positive. corrlation between indoor airpollution and outdoors air pollution (r= 0.82, p< 0.01). Since 2/3 for of one's life are taken inindoor, the long- term effect resulted by indoor air pollution may be greater than atmospheric pollution.
