Abstract:
The cadmium concentrations in mineral mixtures used in beef cattle feed in the states of São Paulo and Paraná, Brazil was measured. The cadmium concentration was determined by inductively coupled plasma atomic emission spectrometry. Of the 36 analyzed samples, 35 had values > 0.5 ppm (range 0.5 to 11.2 ppm), which is the maximum concentration recommended [4, 18]. These findings show the necessity for careful industrial monitoring, as some mineral mixtures contain sufficient cadmium to cause toxicity in animals.

Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...
