Abstract : Formaldehyde is a colourless, reactive and strong smelling gas at room temperature. It is one chemical in a large family of chemical compounds, CH2O, called volatile organic compounds (VOCs). Formaldehyde resins are used in fabrics to bind pigments to the cloth, to enhance wrinkle resistance and water repellency, as well as to provide stiffness and to use as a fire retardant. Increases in temperature (hot days) and increased humidity both increase the release of formaldehyde from coated textiles. Formaldehyde is carcinogenic and allergenic. The permissible limit of formaldehyde content in textiles used in clothing and toys for children under 3 years of age is 30 mg/kg or 2.5 mg/L (The European standard). The aim of this study was to determine and compare the content of formaldehyde concentration of clothing and toys for children. Fifty clothing samples and 50 stuffed toy samples were collected randomly from the various markets in Yangon during January to March 2017. Formaldehyde content was determined by UV/Vis Spectrometry (UVmini-1240, Shimadzu Japan) according to the water extraction method (ISO 1418-1). The result showed that formaldehyde content was in the range of 0 to 4629 mg/kg for clothing samples. Forty-one clothing samples (82%) showed free of formaldehyde. Nine clothing samples (18%) found above the permissible limit of formaldehyde. Among 9 samples, 1 sample showed 154 times higher than the permissible limit. In the toy samples, formaldehyde concentration was in the range of 0 to 57 mg/kg. Formaldehyde was free in all toy samples except one sample. The level of formaldehyde concentration was higher in clothing samples than toy samples. This study showed that high formaldehyde concentration in clothing and toys for children under 3 years of age and recommended that new clothing should be washed before wearing to reduce the level of formaldehyde.
