Heavy Metals 1 article

In food and supplement laboratories, Heavy Metals commonly refers to a screening panel that includes lead, cadmium, arsenic, and mercury. Laboratories may analyze raw materials or finished products, often with trace-element methods such as ICP-MS, and report each metal separately against specifications or action levels. A single 'heavy metals tested' statement is therefore incomplete without the analyte list, sample or lot, detection limits, and results, and it should be kept distinct from microbial or other contaminant testing.
