| Study Title | GC-XLE method development: dSPE and MgSO4 as clean-up for sample preparation |
| Study Type | Untargeted MS anlaysis |
| Study Summary | Compared to using dispersive SPE (dSPE) based on the QuEChERS procedure, we found similar reproducibility using high purity MgSO4 to analyze standard reference material (SRM) of human serum and human plasma samples and slightly higher recovery of targeted chemicals using MgSO4. To avoid contamination by environmental chemicals in solvents and reagents used for QuEChERS, we chose to use high purity MgSO4 to remove water-soluble interferences. |

| 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. |
