Median and range concentrations of grouped PFASs (in ng/g) in red blood cells of red-necked stint (Calidris ruficollis), pacific black duck (Anas superciliosa) and grey teal (Anas gracilis), based on the AIV infection status of each individual.

Where < 0.01 is noted, this means the concentration was below the limit of quantification. Emboldened and bold p values indicate statistical significance between AIV-negative and AIV-positive individuals, for models containing raw or log-transformed PFAS concentrations. Where a value is recorded as NA, this compound was not detected in the species. When p values were adjusted using a Benjamini–Hochberg correction, no significant effects of pollution on AIV infection status were found.
