From: Fluorescent bioassays for toxic metals in milk and yoghurt
Correlations between Zn (II) concentrations in the whey fractions prepared from milk (A and B) or yoghurt (C and D) and zinc concentrations in whole milk or yoghurt determined with ICP-AES. The separately prepared biosensor (A and C) and solid phase biosensor (B and D) were used. The correlation coefficient (R) is shown in each panel.
