Serum concentrations of PFCs (µg/L) in the northern Norway MISA study group (mean parity=0.9 (0–4))

Mean age (range)	31 (18–43)
Sample size	n=391
	Median	Mean (range)
ΣPFOS	8.0	8.8 (0.3–35.8)
PFOS linear	4.7	5.1 (<LOD–19.1)
PFOS branched	3.4	3.7 (<LOD–18.2)
PFOA	1.5	1.7 (0.3–11)
PFNA	0.6	0.7 (0.2–4.4)
PFDA	0.2	0.3 (0.05–2.3)

Data show arithmetic mean (range) for PFCs with detection frequencies greater than 50%.
