Elemental Composition and Strontium Isotopic Ratio Analysis of Industrial Hemp (<i>Cannabis sativa</i> L.) for Textile Applications.

ABSTRACT: Industrial hemp (Cannabis sativa L.) is increasingly valued as a sustainable raw material for textile applications, yet reliable analytical tools to characterize and trace its origin are still limited. This study presents a pilot investigation on the elemental composition and strontium isotopic ratio (⁸⁷Sr/⁸⁶Sr) of Italian industrial hemp samples, with the aim of evaluating their potential as chemical markers for geographic traceability. Hemp stalks and fibers collected from different Italian regions were finely ground, mineralized using microwave-assisted digestion, and analyzed by atomic absorption spectroscopy (AAS), inductively coupled-plasma mass spectrometry (ICP-MS), and multicollector ICP-MS (MC-ICP-MS). The analytical protocol was validated using certi
