TL;DR: Water samples were analyzed for 16 SU, SA and IMI herbicides using high-performance liquid chromatography/mass spectrometry and plants demonstrate a wide range in sensitivity to SUs, SAs, and IMIs with over a 10,000-fold difference in observed toxicity levels for some compounds.

TL;DR: A two-cartridge, solid-phase extraction method for isolating 12 SU, 3 IMI, and 1 SA herbicides by using high-performance liquid chromatography/electrospray ionization-mass spectrometry (HPLC/ESI-MS) to identify and quantify these herbicides to 10 ng/l is developed, demonstrating the usefulness of HPLC/ ESI- MS for determining low-application-rate herbicides at ambient concentrations.
