The European Pharmacopeia Monograph 2.8.13 designates targeted pesticides for monitoring in herbal drugs and herbal preparations. This list targets several dozen common pesticides in use around the world and limits their concentration in herbal products to the low ppm and ppb range. SPEX CertiPrep has created pesticide standards for use with the EU monograph to help the analyst detect pesticides at their critical action levels.
