Fig. 2

Images illustrate the abundance of the isotopic distribution of the precursor [M] and first 13C isotope [M + 1] peak for each chemical across the three ionization modes (ESI[−], ESI[+] and APCI[+]). For each chemical shown (Bosentan, Thiabendazole, and Triamterene), m/z values are plotted on the x-axis, and drift times on the y-axis. Colours represent abundance from red (highest) to green (intermediate), to blue (lowest). The DTXSIDs are the substance identifiers associated with the US EPA’s CompTox Chemicals Dashboard.
