Methods of atomic absorption spectroscopy and atomic emission spectroscopy with inductively coupled plasma were used to determine the content of copper, cadmium, zinc and lead in the water of the Tigris River (Iraq). It is shown that the results of both methods are equally accurate, the difference between them is insignificant and is explained by a random error. The use of Triton X-100 made it possible to reduce the detection limits of metals by 1.5–5 times compared to the standard approach. The mercury content in bottom sediments was determined by the X-ray fluorescence method and the atomic absorption method of cold steam. The found concentration of mercury in the bottom sediments of the Tigris River exceeded, on average, 1.5-2 times the standard values established for it in Iraq (0.2 mg / kg). New reference materials of composition based on acetylacetonates of copper, zinc, cadmium, lead and mercury (I) dimedonate, metal β-diketonates made it possible to increase the precision and accuracy of measurements due to the similarity of the chemical composition of the analyzed and reference samples.
