Uptake of Per- and Polyfluoroalkyl Substances in Mixed Forages on Biosolid-Amended Farm Fields.

When above the limit of detection, PFOSA and NEtFOSAA soil concentrations in individual colocated soil/sward samples ranged from 0.6 to 113 ng/g dw and 0.5 to 421 ng/g dw, respectively. In a linear mixed model, the bivariate relationships between PFOS TF and ln transformed percent organic matter, ln transformed cation exchange capacity, or soil pH did not reach statistical significance ( Table 4 ).
