遵义市公共场所室内空气可吸入颗粒物甲醛监测结果分析

Formaldehyde and Inhalable Particulate Matter in Indoor Air of Public Places in Zunyi City

摘要

摘要:
目的了解遵义市区酒店、餐馆和医院等公共场所室内空气中可吸入性颗粒物、甲醛的污染状况, 为采取相应的室内空气污染控制措施提供科学依据。
方法现场监测公共场所室内可吸入颗粒物(PM₁₀)、甲醛质量浓度、温度和相对湿度。运用Epidata 3.0软件进行数据整理, SPSS 20.0统计分析。
结果在监测的公共场所中, 室内空气中甲醛超标率约为52.3%;室内甲醛平均质量浓度与相对湿度呈显著性正相关(P < 0.01);可吸入颗粒物的超标率为35.6%。
结论遵义市公共场所室内甲醛及可吸入颗粒物污染普遍存在, 影响消费者身心健康, 政府部门应加强对公共场所环境空气质量监测, 有效防止公共场所环境污染事故的发生。

Abstract:
Objectives To investigate the status of indoor air pollution in public places in order to provide scientific basis for enacting relevant measures.
Methods Monitoring concentration of formaldehyde, inhalable particulate matter (PM₁₀), temperature and relative humidity in indoor air on site, and using Epidata 3.0 and SPSS 20.0 software to input and analyze data.
Results The concentration of formaldehyde and inhalable particulate matter in 52.3% and 35.6% of public places monitored in this survey exceeded the limits of the Chinese national standard for indoor air quality. A significantly positive correlation between the concentration of formaldehyde and relative humidity in indoor air was revealed (P < 0.01).
Conclusions The pollution of formaldehyde and inhalable particulate matter in indoor air of public places in Zunyi city was common, which might be harmful to human health. Relevant public health measures should be enacted to improve the quality of indoor air.
