ICP-MS Analysis of Commercial Coffees Available in the US Market

As coffee constitutes a global cultural phenomenon consumed at 9 million tons annually across 167 countries, its scientific studies attract widespread attention. Accordingly, the present study investigates trace elements in coffee samples available in the US market, spanning sensory, health, environmental, and toxicological dimensions. Specifically, the study employs Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for the analysis of 14 elements in 12 diverse coffee brands. Geographical variations, sustainability implications, and a leaching experiment further enrich our understanding. The findings contribute insights for consumers, producers, and regulators, shaping the evolving landscape of the coffee industry.
