No lead and cadmium from ceramics
From a toxicological point of view, the BfR recommends that no lead and cadmium should migrate from ceramics. With modern measurement technology, detection limits in the ppt range (ng/kg food (simulant)) are achieved. Accordingly, a detection limit of 10 µg lead/kg food (simulant) or 5 µg cadmium/kg food (simulant) must not be able to detect the migration of lead and cadmium from ceramic products.
