Lead and Cadmium Determination by ICP-MS
topic
Lead and cadmium are extracted from textile specimens by microwave-assisted acid digestion in nitric acid and hydrogen peroxide mixtures, then quantified by inductively coupled plasma mass spectrometry against certified reference standards; detection limits below 0.1 milligram per kilogram enable compliance verification against REACH limit of 0.5 milligram per kilogram for accessible components.
Role
Mandatory for market surveillance and supply chain compliance verification of textile accessories, buttons, zips, and printed fabrics where lead stabilisers in PVC and cadmium-based pigments represent primary contamination sources regulated under EU toy safety and consumer product chemical safety frameworks.
