Figure 3. Exposome: traces of sartans, antihypertensive drugs, and pain medications were detected in a small subset of RBCs from healthy donor volunteers.

Case studies are described in which the drugs were detected included sartans (green, A), antihypertensive drugs, and pain medications (blue, B). For each metabolite, we provide the original extract ion chromatograms on the background of the whole population (599 samples), molecular formulas, retention times (RT), mass spectra, ¹³C abundance as percentage of the parent m/z peak, and time course levels (y axes indicate integrated peak areas [AU]).
