Heavy metals such as cadmium, arsenic, mercury and lead are all considered toxic and have adverse effects in human metabolism.
Heavy metals in the environment enter the food chain when they bio-accumulate in plants and animals that become food sources. Testing ingredients and finished products for concentrations of heavy metal contamination is an important part of ensuring the food is safe for consumption.
Accurately quantifying heavy metals is not only vital to food safety and consumer health, but can also help identify contaminants and provide important data for process improvement and chemical product formulation development. In addition, it can be used to deter fraudulent labeling of a food’s origin, since the metal content can be used to identify derivation.
