A rapid screening and determination of 59 pesticides from various classes in natural water without sample preparation by high-resolution ultra HPLC–quadrupole time-of-flight mass spectrometry is proposed. The matrix effect is considered on an example of waters with a high (mineral) and low (artesian) salt concentration. It is demonstrated that pesticides can be determined in water using the calibration curve method with an insignificant matrix effect (neonicotinoids, carbamates, and derivatives of uracil, pyridine, and benzoic and aryloxycarboxylic acids) and the standard addition method with a significant matrix effect (triazines, triazinones, triazoles, imidazoles, pyridazinones, organophosphorus compounds, and urea derivatives). The limits of detection were 0.01–10 ng/mL; the analytical ranges for pesticides were 0.04–50 (100) ng/mL. The relative standard deviation of the results does not exceed 15%; the analysis time is 10–15 min.
