Figure 2.

Top: Concentration/area pattern in three locations (Ulatis Creek, UB, Cache Slough C1 and C2) of A) the insecticide dimethoate (green solid line), its TPs omethoate (blue dashed line) and desmethyldimethoate (red dashed line, confirmed level 3) in the March rain event, and B) the herbicide dithiopyr (green solid line) and its predicted TP with CAS #: 128294–56-4 (blue dashed line) in the January rain event. Bottom: annotated plausible MS/MS spectra of the identified transformation products. C) desmethyldimethoate (MSC score 71.4) and D) dithiopyr TP with CAS #: 128294–56-4 (MSC score 92.6). § predicted by MSC; * predicted by CFM-ID.
