摘要
目的 分析湖南省四个城市宾馆(酒店)室内PM2.5浓度及其影响因素,为改善室内空气质量提供参考依据.方法 2021年在湖南省浏阳市、湘潭市、衡阳市、湘西土家族苗族自治州选择67家宾馆(酒店)开展调查,收集基本情况数据,并监测室内空气指标.采用非参数检验进行组间比较,采用多元线性回归模型分析影响因素.结果 三星级及以上宾馆(酒店)、三星级以下宾馆(酒店)、快捷酒店的室内PM2.5平均浓度分别为79、56、51 μg/m3.宾馆(酒店)总体超标率为34.20％,最高超标倍数达到5.62.多重线性回归模型显示,温度、经营客房面积、本场所最近两年是否装修过、湿度是影响三星级及以上宾馆(酒店)室内PM2.5浓度的主要因素,湿度、风速是影响三星级以下宾馆(酒店)室内PM2.5浓度的主要因素,经营客房面积、温度是影响快捷酒店室内PM2.5浓度的主要因素.结论 2021年湖南省四个城市监测的宾馆均存在超标情况,三星级及以上浓度最高,不同宾馆(酒店)室内PM2.5浓度的主要影响因素不完全相同.
Abstract
Objective To analyze the indoor PM2.5 concentration and its affecting factors in hotels of four cities in Hunan Province,and to provide a reference basis for improving indoor air quality.Methods A survey was conducted in 67 hotels in Liuyang City,Xiangtan City,Hengyang City,and Xiangxi Tujia and Miao Autonomous Prefecture in Hunan Province in 2021.General situation data were collected,and indoor air indicators were monitored.Non-parametric tests were used for inter-group comparison,and a multiple linear regression model was employed to analyze the influencing factors.Results The average indoor PM2.5 concentrations in three-star and above hotels,hotels below three-star level and budget hotels were 79 μg/m3,56 μg/m3 and 51 µg/m3 respectively.The overall over-standard rate of the hotels was 34.20％,with the maximum concentration over standard of 5.62 times.The multiple linear regression model showed that temperature,operational room area,recent refurbishment within the last two years and humidity were the main factors affecting indoor PM2.5 concentration in three-star and above hotels.Humidity and wind speed were the main factors for affecting indoor PM2.5 concentration in hotels below three-star level,and operational room area and temperature for budget hotels.Conclusion Over-standard indoor PM2.5 concentration existed in the monitored hotels in four cities in Hunan Province in 2021,with the highest average concentration in three-star and above hotels.Different hotels show varied primary factors influencing indoor PM2.5 concentration.
