| Study Title | Human lung exposomics analysis |
| Study Type | Untargeted MS anlaysis |
| Study Summary | We tested the general utility of XLE in a variety of human biological samples by analyzing human lung and thyroid tissues and stool samples. We quantified 32 environmental chemicals in 11 human lungs, with HCB, PCB-28 and PCB-18 being most frequently detected (10 out of 11). The commonly detected chemicals in human plasma were detected less frequently in the lung. For the 11 lungs, p,p’-DDE was detected in eight, PCB-153 in five, PBDE-47 and PCB-138 in four and PCB-180 in three. Although the plasma samples were from non-diseased individuals and the lungs were both diseased and non-diseased individuals, HCA results suggest that environmental chemical profiles in human lung may be very different from plasma. |

| 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. |
