Table 1 Optimized heating program for GF AAS measurements

From: Aluminum concentrations in central and peripheral areas of malignant breast lesions do not differ from those in normal breast tissues

  1. 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.
