| Abstract: | A survey was conducted in the humid environment of Taipei City during April and May of 1991, to investigate the indoor formaldehyde exposure and its health effects on 117 conventional households. The levels of formaldehyde were measured by the pararosaniline method. The details regarding construction, ventilation, combustion of fuel, burning of Chinese incense, and the complaints concerning the respiratory system were obtained by a questionnaire. The results show that the age of the pressed wood used in furniture and indoor decoration, the ventilation rate, the combustion of fuel, and the burning of Chinese incense significantly affect the levels of formaldehyde. The respiratory complaints found in this study were concluded here to be only partially accounted for by exposure to formaldehyde. |
