Study Title | Human thyroid exposomics analysis |
Study Type | Untargeted MS anlaysis |
Study Summary | In the small number of thyroids that was analyzed with XLE, 14 environmental chemicals were quantified. The most prevalent was p,p’-DDE, detected in 4 out of 5 thyroid samples, with median concentration (2.20 ng/g). The amounts of individual chemicals were highly variable among the individuals, and the small number of samples precludes any generalization. Nevertheless, HCA of correlation matrix showed high correlation of chemicals measured in the thyroid samples was similar to that in the lung and plasma. |

MS Comments: | 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. |
