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

#STUDY
ST:STUDY_TITLE                   	SRM1957 validation using GC-XLE (2)
ST:STUDY_SUMMARY                 	We evaluated quantification using XLE by testing 68 different chemicals (PCB,
ST:STUDY_SUMMARY                 	PBDEs, chlorinated pesticides) in SRM-1958 using external calibration curves
ST:STUDY_SUMMARY                 	(0.05 to 2 ng/mL) and comparing measured values to the reference concentrations
ST:STUDY_SUMMARY                 	reported for SRM. We identified all 40 PCBs that are reported with a reference
ST:STUDY_SUMMARY                 	mass fraction (including certified values and non-certified estimates) in the
ST:STUDY_SUMMARY                 	range of 46.6 to 490 ng/kg in SRM-1958 certificate of analysis (issue date: 11
ST:STUDY_SUMMARY                 	October 2018). Quantification without adjustment for recovery was reproducible
ST:STUDY_SUMMARY                 	with 29 PCB qualifications at >70% and 35 PCBs at >65% of the reference levels.
ST:STUDY_SUMMARY                 	Eleven out of 13 PBDE/PBBs and all 17 organochlorine pesticides were
ST:STUDY_SUMMARY                 	identifiable and reproducibly quantified in this experiment. Therefore, XLE
ST:STUDY_SUMMARY                 	provides sufficient recovery to support accurate absolute quantification of a
ST:STUDY_SUMMARY                 	broad range of environmental chemicals. Overall, XLE supported measurement of 68
ST:STUDY_SUMMARY                 	out of the 70 chemicals that are in the ng/kg range in SRM-1958.

CO:COLLECTION_SUMMARY            	of Standards & Technology (NIST).
CO:SAMPLE_TYPE                   	Blood (serum)
#TREATMENT
TR:TREATMENT_SUMMARY             	50 µL formic acid (Emprove® Essential DAC, Sigma-Aldrich) was added to 200 µL
TR:TREATMENT_SUMMARY             	SRM aliquots and immediately followed by addition of 200 µL hexane – ethyl
