Project Title:Exposure to per- and polyfluoroalkyl substances and lipid profile of breast milk
Project Type:MS analysis
Project Summary:The objective of this study was to investigate whether the maternal levels of PFAS are associated with lipid composition of human breast milk and further, if the changes in composition have impact on the growth of the infants.

Collection:

Collection ID:CO001755
Collection Summary:Blood samples were collected for this study. Plasma was separated within 30 minutes after the blood collection by centrifugation at room temperature. The plasma samples were stored at −80 °C until analyzed.
Sample Type:Blood (plasma)
Storage Conditions:-80℃

Treatment:

Treatment ID:TR001775
Treatment Summary:Sample were stored at -80 as it is, no treatment done.

Sample Preparation:

Sampleprep ID:SP001768
Sampleprep Summary:The serum samples were extracted as follows after randomization of the samples. 90 µl of ecetonitrile (containing the BA+PFAS internal standard mixture (c=200 ng/mL PFASs and 1000 ng/mL Bile acids in acetonitrile) was added to the 40 µl of serum samples. The samples were then vortexted and centrifuged (9600 RCF, 10 minutes). 90 µl of the supernatant was collected and evaporated to dryness. The samples were reconstituted with 40 µl of MeOH/H2O (40%/60%).

MS Type:ESI
MS Comments:PFASs were analysed on a UHPLC-qTOF/MS (Agilent Technologies, Santa Clara, CA, The United States of America) with Acquity UPLC®, BEH C18 (2.1 x 100 mm, particle size 1.7 µm) (Waters Corporation, Milford, MA, The United States of America) column at 50°C with a C18 pre-column for column protection (Waters Corporation, Wexford, Ireland). Mobile phases used for the sample analysis were A: 2mM NH4Ac in H2O:MeOH (70:30) and B: 2mM NH4Ac in MeOH. NH4Ac was used as ionization agent. The samples were kept at 10°C during the whole sample acquisition and 1 µl of the sample volume was injected. The flow rate was set to 0.4 ml/min and the gradient started with 95%A and 5%B with a change after 1.5 minute to 70%A and 30%B, which followed a change after 4.5 minutes to 30%A and 70%B, the last change was after 7.5 minutes with 100%B until the end of run. Gradient program was 18 minutes long. 13 minutes for sample analysis and 5 minutes for clean-up, including equilibration in the end of the run. Maximum pressure limit in the binary pump was set on 850 bar. Dual jet stream electrospray (dual ESI) ion source was used and the ion polarity was on negative mode. The capillary voltage and the nozzle voltage were kept at 4500 V and 1500 V. The N2 pressure was set on 21 psi, with the sheath gas flow as 11 L/min and temperature at 379°C for the nebulizer. The data was acquired with MassHunter B.06.01 software (Agilent Technologies, Santa Clara, CA, The United States of America). MS data processing was performed using open source software MZmine 2.52 (Pluskal et al. 2010).
