An Analysis on Indoor Air Pollution by Formaldehyde in Newly Decorated Rooms

To investigate indoor air pollution by formaldehyde (FD) and explore the concentration and changing tendency in newly decorated rooms \ FD concentration of 391 sampling points in 101 sets were detected and analyzed \ The sampling points of FD>0 10mg/m 3 (over national hygiene standard) were 68 0%, and 2 times higher than the standard were 31 2%;The mean level of FD concentration of reading room was higher than bedroom and bedroom higher than sitting room; The peak time of FD concentrations was in 2 3 months after decoration rather than in the first month \ The indoor FD pollution is serious in newly decorated rooms, especially in first three months Opening the windows frequently for one year can reduce FD concentration
