Study TitleRecovery of internal std in SRM-1957
Study TypeUntargeted MS anlaysis
Study SummaryValidation of XLE quantification using standard reference material. High recovery of [13C] labelled chemicals was obtained for important classes of environmental chemicals (PCB, PBDE, PAH, chlorinated pesticides) in NIST SRM-1957. Recoveries ranged from 110±7% for [13C10]mirex to 91 to 105% for congeners of universally [13C] labeled PCBs, PBDEs and chlorinated pesticides, with only [13C12]p,p’-dichlorodiphenyldichloroethylene (p,p’-DDE) having low recovery of 65±6%. Therefore, the simplified extraction procedure provides an efficient recovery of environment chemicals in an organic phase.

Project Title:A scalable workflow for the human exposome
Project Type:Untargeted GC-MS quantitative analysis
Project Summary:Complementing the genome with an understanding of the human exposome is an important challenge for contemporary science and technology. Tens of thousands of chemicals are used in commerce, yet cost for targeted environmental chemical analysis limits surveillance to a few hundred known hazards. To overcome limitations which prevent scaling to thousands of chemicals, we developed a single-step express liquid extraction (XLE), gas chromatography high-resolution mass spectrometry (GC-HRMS) analysis and computational pipeline to operationalize the human exposome. We show that the workflow supports quantification of environmental chemicals in human plasma (200 µL) and tissue (≤ 100 mg) samples. The method also provides high resolution, sensitivity and selectivity for exposome epidemiology of mass spectral features without a priori knowledge of chemical identity. The simplicity of the method can facilitate harmonization of environmental biomonitoring between laboratories and enable population level human exposome research with limited sample volume.

Collection:

Collection ID:CO001869
Collection Summary:SRM1957 are non-fortified standard reference material of human serum developed for analysis organic contaminants. Aliquots were purchased from National Institute of Standards & Technology (NIST).
Sample Type:Blood (serum)

Treatment:

Treatment ID:TR001889
Treatment Summary:50 µL formic acid (Emprove® Essential DAC, Sigma-Aldrich) was added to 200 µL SRM aliquots and immediately followed by addition of 200 µL hexane – ethyl acetate (2:1 v/v, ≥99% pure, Sigma-Aldrich) containing the internal standards (final concentration: 1 ng/mL). The sample mixture was shaken vigorously on ice using multi-tube vortexer (VWR VX-2500) for 1 h and centrifuged at 1000 g, 4 °C for 10 min. The sample mixture was chilled during entire extraction procedure. The organic supernatant was transferred to a new tube with 25 mg MgSO4 (≥99.99% pure, Sigma-Aldrich) and vortexed vigorously to remove water. After 10 min centrifugation at 1000 g, 80 µL of the final supernatant was spiked with instrumental internal standards (final concentration: 1 ng/mL) for analysis. Two 13C labeled chemicals [13C12]PCB-28 and [13C12]PBB-153 were used as volumetric internal standards added to the final extract, and nine 13C labeled chemicals (99% isotope enrichment for each) were spiked as recovery standards to estimate chemical recovery efficiency by XLE: [13C12]PCB-101, [13C12]PCB-153, [13C12]PCB-180, [13C12]PBDE-47, [13C12]PBDE-99, [13C6]anthracene, [13C10]mirex, [13C6]cis-permethrin, and [13C12]p,p’-DDE.

Chromatography:

Chromatography ID:CH002163
Chromatography Summary:Samples were analyzed with three injections using GC-HRMS with a Thermo Scientific Q Exactive GC hybrid quadrupole Orbitrap mass spectrometer with 2 µL per injection. A capillary DB-5MS column (15 m × 0.25 mm × 0.25 µm film thickness) was used with the following temperature program: hold 75 °C for 1 min, 25 °C/min to 180 °C, 6 °C/min to 250 °C, 20 °C/min to 350 °C and hold for 5 min. The flow rate of the helium carrier gas was 1 mL/min. Ion source and transfer line temperatures were 250°C and 280°C, respectively. Data were collected from 3 to 24.37 min with positive electron ionization (EI) mode (+70 eV), scanning from m/z 85.0000 to 850.0000 with a resolution of 60,000.

Raw data were examined by checking signal-to-noise ratio, peak shape and spectral information for surrogate and internal standards using a 5 ppm m/z tolerance and 30 s retention time window in xCalibur Qualbrowser software. Data extraction was performed by XCMS to generate about 40,000 chemical features identified by spectral m/z and retention time.
