Abstract

Western Sichuan region has a variety of traditional heating methods and excellent outdoor air quality, and the difference with the city is clear. The indoor air quality of the western Sichuan region is worth studying. The diffusion law of indoor and outdoor PM2.5 concentration under different heating methods can be explored to provide effective data support for environmental governance. In this context, the indoor air quality under different heating methods in Songpan County was measured with PM2.5 concentration assessment of indoor air quality (IAQ). By analyzing the indoor air quality under different heating modes, the following conclusions can be drawn: the influence degree of indoor activity on indoor particle concentration level depends on the source and characteristics of the house. Air leakage is one of the main reasons for the rise of indoor PM2.5. Heating methods disturb the indoor air, which significantly affects the migration of PM2.5.

Highlights

Most people spend more than 85% of their time in a variety of indoor environments, and particulate matter assessment of indoor air quality (IAQ) has become one of the important topics in air pollution research
The increasing and decreasing trend of indoor PM2.5 concentration is consistent with the changing trend of outdoor PM2.5 concentration, indicating that air leakage has a certain influence on indoor PM2.5 concentration
The reason is that the indoor air disturbance will be caused when the air heater is heating, and the air disturbance will lead to the migration of indoor PM2.5

Summary

Introduction

Most people spend more than 85% of their time in a variety of indoor environments (home, school, office and restaurant), and particulate matter assessment of indoor air quality (IAQ) has become one of the important topics in air pollution research. Chunram et al [7] found that in the urban area of Chiang Mai, the monthly average indoor PM2.5 mass concentration of residential buildings was 13.6-57.9 μg/m3, and that of workplaces was 9.9-58.5 μg/m3. He et al.[8] showed that in the process of smoking, barbecue and frying, indoor PM2.5 concentration could be increased by 3 times, 30 times and 90 times of the background value, respectively.
