Objective To investigate the current formaldehyde pollution levels in the decoration materials in Beijing. Methods Some of the detecting samples were collectted selectively by sampling and some were provided by the manufacturers voluntarily. The contents of formaldehyde in the samples were determined according to the National Standard Detecting Method for the threshold of harmful substances in decoration materials. Results The emission levels of formaldehyde in 15 of 27 man-made board samples were higher than 1.5 mg/L and the rate exceeding the national standard was 56%. The formaldehyde emission level from 1 of the 4 wall-dope samples was higher than the national standard. In 7 gooey samples,the content of formaldehyde in 1 sample was higher than the national standard. The detecting results of 3 wallpaper samples were all accorded with the national hygienic standard. Conclusion The results of this investigation indicated that some problems did exist in the current decoration materials made in our country. The relatively serious problem among them was that the emission level of formaldehyde from the man-made boards and its related products was much higher than the national standard.
