Data Analysis for High Throughput Detection of 18 Phthalates in Textiles Based on High Resolution Mass Spectrometry

Liquid chromatography coupled to high resolution mass spectrometry(LC-HRMS) was used to establish a high throughput and sensitive method for 18 phthalic acid esters(PAEs) in textiles. The method was applied to screen PAEs in 413 textile samples and 7 434 pieces of test data were analyzed. Further discussion was conducted about specific compounds, textile materials, detected value distribution and positive rate of samples. Twenty-nine percent of samples were detected with PAEs, and no samples were detected beyond regulations. Diisobutyl phthalate(DiBP), Dibutyl phthalate(DBP) and Di-2-ethylhexyl phthalate(DEHP)were detected with high frequency, and most samples were fabrics with coating and printing. This study can be used to reflect distribution of phthalate residues in textiles on the market and provide data support for risk assessment of PAEs for textile producers and consumers.
