This study aimed to investigate factors influencing formaldehyde pollution in the air, with a particular focus on the effects of house decoration. Several new residential areas in Wuhan were chosen, from which, 100 houses that had been decorated for 1 year or less were selected. A portable meter was utilized to measure the concentration of indoor formaldehyde. At the same time, a questionnaire on the topic of formaldehyde concentration influence factors was carried out with residents living in the selected houses. In the 100 houses selected, different types of rooms were found to have different formaldehyde concentrations. Formaldehyde concentration was found to be highest in the master bedroom while levels decreased in the study room, guest bedroom and living room, respectively. Formaldehyde concentration in the wardrobe was significantly higher than that detected in any area of the other rooms (p<0.05). Differences in the time of decoration were shown to significantly influence formaldehyde concentration (p<0.01). Different ventilation systems were also seen to affect the formaldehyde concentration in the air; the average formaldehyde concentration of regular ventilation was significantly lower than in occasional ventilation (p<0.05). The results suggested that formaldehyde pollution in new residential houses is significant. The main factors influencing indoor formaldehyde concentration were the level of decoration, time since decoration and the type of ventilation system used.
