Mean Concentration

The concentration of Al, P, and Si in 142 samples of five fruit juices, measured with neutron activation analysis and atomic absorption spectroscopy, varies from 0 to 1.44, 31 to 201, and 1.5 to 35 µg/mL, respectively. The mean concentration of Al in apple, grape, grapefruit, orange, and pineapple juices is 0.54, 0.94, 0.24, 0.29, and 0.62 µg/mL, respectively. The mean concentration of P in the same juices is 102, 115, 124, 127, and 76 µg/mL. The storage of juice in aluminized containers with internal plastic coating does not increase the concentration of Al in the juice.
