Regular monitoring of the elemental composition of water resources is necessary to maintain the ecological balance and protect the environment. Water pollution by heavy metals has become a global and particularly serious problem due to toxicity to living organisms even at very low concentrations. Therefore, effective and reliable detection of heavy metals in ambient water is very important. The study was conducted in the Ukrainian Laboratory of Quality and Safety of Agricultural Products of the NUBiP of Ukraine, accredited according to the DSTU ISO/IEC 17025 standard. The purpose of the study was to determine the content of chemical elements, including heavy metals, in water samples from various sources in the Kyiv region to assess their quality and compliance with regulatory standards . One of the modern methods that has been used for the qualitative and quantitative assessment of the content of chemical elements, including heavy metals, is atomic emission spectrometry with inductively coupled plasma (ICP-AES), which is characterized by high sensitivity, accuracy and responsiveness, which makes it suitable for the analysis of inorganic substances in water samples. Based on the comparative analysis of the elemental composition of the water samples, the following conclusions were drawn that the concentrations of cobalt (Co), cadmium (Cd), lead (Pb), nickel (Ni), chromium (Cr) and copper (Cu) in the water samples are negligible. This indicates that the level of these metal ions in the water is acceptable and does not exceed the normative values. According to the analyzes carried out, the concentrations of zinc (Zn), manganese (Mn), molybdenum (Mo), arsenic (As), bismuth (Bi) and mercury (Hg) are within the established standards. The results of the study show that the water bodies of the Kyiv region are in a stable state from the point of view of the content of heavy metals. Continuous monitoring allows timely detection and response to possible changes in water composition, preventing negative consequences for ecosystems and public health.
