a

All significant results were positively correlated. Values were calculated using log normal concentrations.

b

Indicates significant correlation coefficients.

c

Indicates a correlation coefficient determined using the Pearson correlation. All other correlation coefficients were determined using the Spearman correlation.

*

Correlation is significant at the 0.05 level (2-tailed).

**

Correlation is significant at the 0.01 level (2-tailed).

PFOA = perfluorooctanoic acid; PFNA = perfluorononanoic acid; PFDA = perfluorodecanoic acid; PFUnA = perfluoroundecanoic acid; PFDoA = perfluorododecanoic acid; PFTA = perfluorotetradecanoic acid; PFTriA = perfluorotridecanoic acid; PFHxS = perfluorohexanesulfonic acid; PFOS = perfluorooctane sulfonate.
