jailcd2018052: Indoor Air Quality Analysis of Hospitals in Changchun

Abstract

Hospital indoor air quality (IAQ) affects the health of doctors and patients. The method of continuous testing in this paper is adopted in this paper,the average concentration of fine particulate matter (PM2.5), formaldehyde (HCHO) and carbon dioxide (CO2) in indoor air of five large hospitals in Changchun was tested. The results showed that the concentration of fine particulates in five large hospitals did not exceed the standard. Although all five hospitals have been in hospital for at least five years, there are serious levels of formaldehyde in the house. Indoor carbon dioxide concentration exceeds the standard. It is recommended to adopt the new air system or air purification system to improve the indoor air quality.
