Summary:Field observations on indoor air quality were carried out in 32 households from December 7th 2016 to January 20th 2017 in Tianjin, China. Each household was visited twice by researchers to compare the pollutants concentration inside homes between normal conditions and closed conditions (windows and doors were closed for 12h). Concentration of formaldehyde was measured using the spectrophotometry method. Other pollutants concentrations including PM2.5, PM1, PM0.1, TVOC were measured with direct-reading instruments. Results revealed that formaldehyde concentration in closed condition was slightly higher than that in normal condition. Outdoor particles and indoor activities both had impact on indoor particulate matter.
