Abstract: In this work, the content of formaldehyde is determined in 134 samples from 35 models footwear of which thirteen models correspond to men's footwear, ten models for women, seven models for children and five sport type. The samples were obtained from several parts the finished footwear (court, lining, insole, outsole, accessories) and classified according to: i) the model and ii) type of material: leather and textile. The extraction of formaldehyde from several samples was conducted using 0.1% sodium dodecyl benzene sulphonate as extracting agent, derivatizing with 2,4-dinitrophenylhydrazine and subsequent separation/determination by High Performance Liquid Chomatography(HPLC) with UV detection. The results show that formaldehyde content in the footwear models were in the range of 17.6 to 164 mg/kg for men; 6.74 to 125 mg/kg for women; 17.3 to 157 mg/kg for children and 21.5 to 107 mg/kg for sports. The highest formaldehyde concentrations were found in leather samples, exceeding the permissible limit of 65 mg/kg for adults; while the remaining models for children exceed the permissible limits of formaldehyde in leather 16 mg/kg by children.
