Figure 4. Exposome: traces of antiinflammatory drugs, antidepressants, and sleep aids were detected in a small subset of RBCs from healthy donor volunteers.
Case studies are described in which NSAIDs and other antiinflammatory drugs (gold, A), antidepressants, and sleep aids (red, B) were detected. For each metabolite, we provide the original extract ion chromatograms on the background of the whole population (599 samples), molecular formulas, retention times, mass spectra, 13C abundance as percentage of the parent m/z peak, and time course levels (y axes indicate integrated peak areas [AU]).
