The aim of this study is to analyze the elemental composition of water samples from bodies of water in the Kyiv region. The results will allow determining the content and distribution of heavy metals in the surface waters of the region, which is important for developing measures for the protection, rational use, and restoration of water resources. The study was conducted at the Ukrainian Laboratory of Quality and Safety of Agricultural Products of NUBiP of Ukraine, which is accredited according to the DSTU ISO/IEC 17025 standard. The elemental composition of the water samples was measured using an inductively coupled plasma atomic emission spectrophotometer (ICP-AES). This method allows for precise determination of the concentrations of various chemical elements in water samples. The detection limit for most elements is 0.01 mg/dm³, ensuring the detection of even very low concentrations of elements in water samples. To ensure the accuracy and reproducibility of the results, a multi-element standard solution IV from Merck KGaA, Germany, was used. The analysis of water bodies in the Kyiv region showed a low content of heavy metals, which is a positive indicator of the ecological situation in the region. This indicates a satisfactory state of water resources, which does not require immediate measures to minimize pollution. The content of heavy metals in the water bodies of the Kyiv region is low, which positively affects the ecological situation in the region. Data on the elemental composition of water allow assessing the risks of agricultural product contamination and predicting the likelihood of safely growing environmentally clean products. The results of the study are an important step for the preservation of the natural environment and ensuring the health of the region's residents. Thus, regular monitoring of the elemental composition of water resources is necessary to maintain ecological balance and ensure environmental safety.
