Furnishing textile materials may be a source of formaldehyde (CH2O) re-emission if this compound is present in the environment. In the examinations performed the effect of temperature (23 degrees C, 35 degrees C) and air humidity (RH: 45%, 85%) upon CH2O re-emission from curtain materials was determined. The source of CH2O emission was particle board. CH2O emission was determined in small glass chambers (13.08 dm3) in controlled conditions, one air exchange per hour at loading factor of 1 m2/m3. The results of these examinations showed that the effect of temperature and humidity upon CH2O adsorption and desorption was different. Increase of temperature from 25 degrees C to 35 degrees C caused increase of the magnitude and rate of CH2O re-emission and the phenomenon intensified at high air humidity.

D005557	Formaldehyde	A highly reactive aldehyde gas formed by oxidation or incomplete combustion of hydrocarbons. In solution, it has a wide range of uses: in the manufacture of resins and textiles, as a disinfectant, and as a laboratory fixative or preservative. Formaldehyde solution (formalin) is considered a hazardous compound, and its vapor toxic. (From Reynolds, Martindale The Extra Pharmacopoeia, 30th ed, p717)	Formalin,Formol,Methanal,Oxomethane
