- Note: Correlation coefficients for Aluminum concentration and the water content of the samples were: 0.23 for normal tissues; 0.26 for peripheral tumor areas, and 0.16 for peripheral tumor areas, showing that samples with increased water content (and therefore lower fat content) had slightly higher concentrations of aluminum.
