编者按:本项目曾获第二十届(2005)全国青少年科技创新大赛医学与健康类二等奖。

[摘要]   本文通过对广州市民的问卷调查,了解市民在搭乘空调公共汽车时的主观感受、生理反应以及他们对车内空气质量现状的认知程度;同时,应用先进的检测技术着重对广州空调公共汽车内CO2浓度、菌落总数、可吸入颗粒物以及CO、甲醛、等效噪声、温度、相对湿度、压强共九个项目进行了检测;在广州普通公共汽车、地铁、大型公共场所以及英国伦敦空调公共汽车进行了相关实验,并进行空调车内CO2浓度和乘客感觉的同时检测和问卷调查;对实验结果应用统计方法进行处理分析,取得了有意义的结果;在此基础上,利用数学建模方法设计出一套空调车内空气质量的评估软件,较好地探讨了车内空气质量与人体健康的关系;本研究还针对存在的问题,提出合理化建议,对空调车内空气质量的整改有一定的参考价值。

A Study of Air Quality in An Air-conditioned Bus and Human Health

Fu Mao-jingThe Affiliated School, South China Normal University,

510630 Guangzhou, P.R.China

Abstract:  By a questionnaire survey holding in Guangzhou to know about the residents’ subjective feelings, physiological reaction while taking an air-conditioned bus, and their cognition to the present condition of the bus inside air quality, in application of the advanced detecting techniques, nine items of CO2, total number of bacterial colony, particulate pollutant, CO, formol, equivalent noise, temperature, relative humidity, pressure were detected. The related experiment was also held on Guangzhou ordinary buses, the Metro, large scale public sites and London air-conditioned buses. A simultaneous questionnaire survey of subjective feelings of passengers was held along with the CO2 detection inside the air-conditioned bus. With the findings processed and analyzed in statistical methods, significant results were drawn out. On this basis, with mathematical model method introduced, an evaluation software  was designed, the relationship between the air quality inside an air-conditioned bus and human health was analyzed better. In the light of the existing problems, reasonable suggestions were put forward, providing reference for improvement of the bus inside air quality.

Key words: air-conditioned bus, air quality,  human health,  mathematical model,  evaluation software
