Dynamic Changes of Indoor Air Quality in a Mall

摘要

摘要:
目的分析某商场影响环境空气质量各项指标的动态变化趋势并建立危险因素预警体系。
方法收集该商场2012年1月9日到2012年12月22日的空气质量各项指标的数据, 包括:可吸入颗粒物(PM₁₀)、甲醛、一氧化碳(CO)、二氧化碳(CO₂)、温度、湿度, 对这些指标动态浓度进行描述和分析。
结果营业中商场卖场PM₁₀、甲醛(HCHO)、一氧化碳(CO)、二氧化碳(CO₂)、温度、相对湿度分别为:0.07 mg/m³、0.07 mg/m³、3.5 mg/m³、0.065%、24.2℃、36.9%。
结论商场内甲醛在"五一"到"十一"这段时间污染最重(超标率), PM₁₀在店庆周污染较重, 相对湿度难达要求, 其它指标基本合格。

Abstract:
Objectives To analyze the changing trend for indicators influencing the environmental quality in a mall and to establish an early warning system.
Methods The samples for the air quality in the market was collected from January 9, 2012 to December 22, 2012, and the indicators were PM₁₀, formaldehyde, CO, CO₂, temperature and relative humidity.
Results The results of PM₁₀, formaldehyde, CO, CO₂, temperature and relative humidity fluctuated up and down during business hours and were around 0.07 mg/m³, 0.07 mg/m³, 3.5 mg/m³, 0.065%, 24.2℃ and 36.9% respectively.
Conclusions The pollution of formaldehyde was the worst especially in the May Day and the National Day. The pollution of PM₁₀ was heavier in the week for the anniversary of the mall. Relative humidity was difficult to reach the standard requirement, and other indicators were qualified basically.
