Flame atomic absorption is a very common technique for detecting metals and metalloids in environmental samples. It is very reliable and simple to use.
The SMGs (specific migration limits) on lead and cadmium are being reduced and requirements added for compliance on other metals. Testing must be in accordance with European Standards: EN 1388-1 and EN 1388-2. The migration of elements into a food simulant (4% acetic acid) is measured, by accredited methods according to EN ISO/IEC 17025:2005, using FAAS (flame atomic absorption spectrometry). It is a rapid and generally robust interference-free technique having simple external standardization with matrix-matched solutions. Exposure assessment is performed taking into account actual reference doses introduced by the European Food Safety Authority (EFSA) and the Joint FAO/WHO Expert Committee on Food Additives (JECFA). How can one deal with this? Check the limit recipe, leaching and toxicity topics. For maximum assurance, develop your own base recipe and variegate that.
