Risk assessment analysis on extractable heavy metals in textiles

Contents of extractable heavy metals in 35 kinds of textiles originated from EC and 69 kinds from China were determined according to the method of Oeko-Tex Standard 100.Textiles of EC and China origin were distinctively classified by linear discriminate analysis(LDA) based on the data of extractable heavy metals,and the extractable heavy metals having great effects on the classification were explained by linear discriminate function;the main factors which determined the discrepancy of textiles between the two origins in extractable heavy metals were investigated based on the scores of variables by factor analysis(FA).
