Approximate output of urinary (rev/12 h) and fecal (rev/movement) mutagenicity.

aMean for 10 subjects.
bMean for 60 subjects.
cValues converted from mean mutagenic potencies in rev/µmole
creatinine (Fig. 2A and
2B) assuming 13964 µmole creatinine per 12 h urine
sample. This conversion factor was a median based on 36 samples (4
samples each for 8 subjects; 1 sample each for 4 subjects) of first
morning voids. Although we measured creatinine concentrations for
all 64 samples (4 samples each from 16 subjects), we failed to
record urine volume for 28 (4 samples each for 4 subjects plus 3
samples each for 4 subjects).
dValues converted from mean mutagenic potencies in rev/mg lyophilized
feces (Fig. 2C and
2D) assuming 19.32 g lyophilized feces per movement. This
conversion factor was a median based on 32 fecal samples (2 samples
each for 16 subjects).
