Table 2. Spearman Rank Correlation Coefficients between Log10 Concentrations of Select PFASs in Maternal Serum at 16 Weeks Gestation, At Birth, And in Infant Cord Serum (n = 71 Mother–Infant Pairs)a,b.
analyte | maternal serum at 16 weeks and at birth (N = 71) | maternal serum at 16 weeks and infant cord serum (N = 182) | maternal serum at birth and infant cord serum (N = 78) |
---|---|---|---|
Me-PFOSA-AcOH | 0.84 | 0.73 | 0.92 |
PFHxS | 0.92 | 0.95 | 0.89 |
PFOS | 0.87 | 0.83 | 0.82 |
PFOA | 0.94 | 0.92 | 0.88 |
PFNA | 0.88 | 0.77 | 0.79 |
Selected PFASs were those detected in >60% of samples at all time points.
P values for all the comparisons were <0.05.
