The inorganic lead concentration in mineral mixtures used in various cities in beer cattle in the state of Sao Paulo, Brazil was measured by inductively coupled plasma atomic emission spectrometry. Of the 45 analyzed samples (range 3.0 to 4,386 ppm), 34 sample had lead concentration above 10 ppm, which is the proposed acceptable maximum limit. These findings show the necessity for careful industrial monitoring in Brazil, as some mineral mixtures may contain sufficient concentrations that can cause toxicity in animals.
