Standards and Reagents
A mixture of 17 native linear PFAAs (PFAC-MXB) including Perfluorobutanoic acid (PFBA),
Perfluoropentanoic acid (PFPeA), Perfluorohexanoic acid (PFHxA), Perfluoroheptanoic acid
(PFHpA), Perfluorooctanoic acid (PFOA), Perfluorononanoic acid (PFNA), Perfluorodecanoic
acid (PFDA), Perfluoroundecanoic acid (PFUnDA), Perfluorododecanoic acid (PFDoDA),
Perfluorotridecanoic acid (PFTrDA), Perfluorotetradecanoic acid (PFTeDA),
Perfluorohexadecanoic acid (PFHxDA), Perfluorooctadecanoic acid (PFODA), Potassium
Perfluorobutanesulfonate (PFBS), Sodium Perfluorohexanesulfonate (PFHxS), Potassium
Perfluorooctanesulfonate (PFOS), Sodium Perfluorodecanesulfonate (PFDS) and a mixture of 9
mass-labeled linear PFAAs (MPFAC-MXA) including PFBA [1,2,3,4 13C], PFHxA [1,2,3,4
13C], PFOA [1,2,3,4 13C], PFNA [1,2,3,4 13C], PFDA [1,2,3,4 13C], PFUnDA [1,2,3,4 13C],
PFDoDA [1,2 13C], PFHxS [1,2 18O] and PFOS [1,2,3,4 13C] were purchased from Wellington
Laboratories with purities of >98% (Guelph, Ontario, Canada). HPLC grade methanol and
acetonitrile (ACN) were purchased from J.T. Baker (Phillipsburg, NJ, USA). Ammonium acetate
(~98%) and ammonium hydroxide solution (28%~30% NH3 basis) were purchased from Sigma-
Aldrich Co. (St. Louis, MO, USA). Milli-Q water was obtained from a Milli-Q synthesis A10
(Millipore, Bedford, MA, USA) and used throughout the experiment.
Quality Assurance and Quality Control (QA/QC)
To minimize background contamination, use of polytetrafluoroethylene (PTFE) or other
fluoropolymer materials was avoided during collection and extraction of samples as much as
possible. In order to avoid cross contamination in the field sampling, after the samples were
taken, outside of the PP bottles were washed thoroughly with Milli-Q water, wiped with clean

towel paper and then kept in three-layers sealed PP bags for further storage and transportation.
Field blank and transportation blank prepared in Milli-Q water were introduced to monitor if
there was still cross contamination after this treatment. To monitor cross and background
contamination during extraction and clean-up, procedure blanks were executed along with every
sample batch by use of Milli-Q water. Solvent blank was prepared using 100% methanol and ran
after 10 samples to monitor background contamination of the instrument and minimize cross
contamination. A guard column immediately in front of the injector loop was used to displace
any contaminants introduced in the instrument from analytes in samples. No detectable PFAAs
were observed at concentrations greater than the Limit of Quantification (LOQ) in any of the
field, transport, procedure or solvent blanks. Concentrations of PFAAs greater than the LOD in
blank samples were not used to correct concentrations in this study.
Concentrations of 12 PFAAs in water were quantified using 10-point external calibration
curves containing a concentration series of 0.01, 0.1, 0.5, 1, 5, 10, 50, 100, 500 and 1000 ng/mL,
and 10 ng/mL of mass-labelled standards were used for surrogates. Curves for all PFAAs
showed strong linearity with R2 > 0.99 and the deviation of every calibration point was less than
±20% from its theoretical value. The concentration of 10 ng/mL in the calibration curve was
also used as calibration check standard (CCS) and ran after every 10 samples. When the
deviation of a CCS was more than ±20% from its theoretical value, a new calibration curve was
prepared. For concentrations of PFAAs in any extracts measured over 1000 ng/mL for the first
time, the volume of the samples would be reduced and the samples would be extracted again to
make sure the concentrations of PFAAs in the final extracts fall in the range of the calibration
series.

In order to assess overall efficiency of extraction, two kinds of recovery experiments were
performed (Loi et al., 2011). For procedure recovery test and matrix spike recovery test in water,
20 ng mixtures of 12 native PFAAs standards were spiked into 400 mL Milli-Q water via 4
duplicates and 400 mL water samples at site 1, 2, 17 and 18, respectively. Results are listed in
Table S3.
The limit of detection (LOD) was defined as the lowest concentration that provided a
signal/noise (S/N) > 3 (peak height), and the limit of quantification (LOQ) was defined as the
lowest concentration providing S/N >10. Both values were determined in three successive
injections with a standard deviation less than 20%. The values are listed in Table S3.
