Inventing The Most Sensitive Heavy Metals Detection Method

Testing for safety in soil, water, food and pharmaceuticals

Heavy metals in foodstuffs such as fish and seafood, fruits and vegetables, and nuts and cereals are a serious threat to health. Exposure to even small amounts of cadmium, lead, mercury or arsenic can prove to be extremely toxic as they accumulate in the liver and other organs. Eurofins’ pioneering tests for these substances can detect the minutest traces.

Heavy metals in the environment, in substances such as soil and water, can find their way into the food chain and pose a serious risk to consumers. The products most likely to contain these heavy metals are biological – those wholly or partly derived from biomass such as plants, trees and animals – and pharmaceuticals. Comprehensive detection of the presence of toxic materials in such products helps ensure the safety of the foodstuffs we consume and the medicines we take. By working with the latest available technology, using state-of-the-art instrumentation, and refining best practice methods, Eurofins Specialty Metals Testing, formerly known as Eurofins Frontier Global Sciences, has helped to pioneer some of the industry’s lowest detection limits for toxic trace metals in the environment. Operating in the cleanest possible testing environment is paramount, and the lower the detection level, the greater the importance of avoiding contamination, even at minute levels.

The US’ Environmental Protection Agency (EPA) hired Eurofins as its trace metals and metals speciation reference and validation laboratory, asking the company to perform the final validation of what developed into the US EPA 1600 series methods for waters, soils/sediments and biological tissues. Today, these principles are adopted for compliance monitoring around the world.

Eurofins’ presence and expertise in numerous other sectors meant that these methods had applications in a number of markets and industries outside environmental testing, and the company has expanded the tests’ reach to dietary supplements, the food and beverage sector, and pharmaceutical products.

Furthermore, the work of Eurofins laboratories became a catalyst for both industry and the regulatory community in shaping policy in several of these areas. For example, the value of differentiating different forms of arsenic in samples - such as arsenite and arsenate - helped provide the scientific means to develop policy in the food and environmental sectors due to the differing levels of toxicity of these forms of arsenic.
