Analysis of Volatile Organic Compounds in Textiles: Insights from GC–MS with Metal Content Assessment Using ICP-MS
Summary
Researchers applied headspace GC-MS and ICP-MS to analyze volatile organic compounds and trace metals in textile samples of different origins and compositions. PCA distinguished textiles by chemical profile with origin, revealing distinct VOC signatures from Asian and European textiles and detecting hazardous compounds including phthalates and chlorophenols, with implications for textile chemical safety and microplastic-associated chemical release.
This study primarily focuses on the analysis of volatile organic compounds using GC–MS, with ICP-MS employed as a complementary method to quantify trace metal content. Headspace GC–MS was conducted to detect alkylphenol ethoxylates (APEOs), formaldehyde, aromatic amines derived from azo dyes, perfluorinated carboxylic acids, chlorophenols (PCPs), tetrachlorophenols (TPCs), and phthalates in textile samples of different origin and composition. Principal component analysis was used to detect patterns in the volatilome according to the origin and the textile composition. In addition, seven metals (Cr, Ni, Cu, Mo, Cd, Hg, and Pb) were quantified in a subset of samples. The study revealed distinct chemical profiles in textiles based on their origin, with GC–MS identifying key volatile organic compounds and ICP-MS quantifying heavy metals in a subset of samples. Principal component analysis highlighted cotton content as a critical factor in differentiating textile profiles. While most samples adhered to regulatory standards, some exceeded thresholds for metals like copper and nickel, underscoring the need for enhanced quality control in manufacturing processes. By integrating advanced analytical methods, this study provides insights into sustainable and safe textile production, offering valuable benchmarks for regulatory compliance and industry best practices. The outcomes contribute to improving product safety, promoting responsible manufacturing, and supporting regulatory bodies in the enforcement of environmental and safety standards, aligning with the growing demand for sustainability in the textile sector.

Suspect and non-target screening of chemicals in clothing textiles by reversed-phase liquid chromatography/hybrid quadrupole-Orbitrap mass spectrometry
Researchers chemically screened 24 imported garments sold in Sweden and detected dozens of hazardous compounds including carcinogenic quinoline, mutagenic nitroanilines, phthalates (plasticizers), and organophosphates — several at concentrations exceeding regulatory limits. Because clothing stays in prolonged contact with skin and many of these chemicals can be absorbed through it, the study raises significant concerns about unregulated chemical exposure from everyday clothing.
