This study focuses on the quantitative determination of trace metal concentrations in edible mushroom samples using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). Mushrooms are known for their remarkable ability to accumulate essential and non-essential elements from their growth substrates, making them valuable bioindicators of environmental contamination. In this work, representative mushroom samples were collected from the market in Nellore, Andhra Pradesh, India. They are digested using a microwave-assisted acid digestion method before ICP-MS analysis. The concentrations of essential elements such as Fe, Zn, Cu, and Mn, along with potentially toxic metals including Pb and As, were accurately measured. Results show a considerable variation in metal accumulation among the samples, reflecting differences in soil composition and environmental exposure. Essential metals were found within acceptable nutritional ranges, while trace amounts of toxic elements were detected in certain samples, though generally below the permissible limits set by WHO and FAQ. The precision and sensitivity of ICP-MS enabled reliable quantification even at sub-ppb levels, demonstrating its superiority for multi-elemental analysis. These findings highlight the importance of continuous monitoring of metal content in edible mushrooms to ensure food safety and to assess their potential role in environmental pollution studies.
