ANALYSIS OF THE ELEMENTAL COMPOSITION OF WATER RESOURCES OF KYIV REGION

Abstract

Continuous monitoring of water resources is crucial for maintaining ecological balance and protecting the environment. Water pollution by heavy metals poses a significant global threat due to their high toxicity to living organisms, even at low concentrations. Therefore, reliable and accurate detection of heavy metals in water is essential to ensure its safety. The research was conducted at an accredited testing laboratory of the National University of Life and Environmental Sciences of Ukraine. The study aimed to assess the content of chemical elements, particularly heavy metals, in water samples from various sources in the Kyiv region. Inductively coupled plasma atomic emission spectrometry (ICP-AES), known for its high precision and sensitivity, was utilized. Sources of heavy metal pollution include industrial emissions, agrochemicals, and improper waste disposal, contributing to the accumulation of these elements in the environment, especially in air, soil, and water. Effective detection of heavy metals in water is critical for quality control. Research conducted in the Kyiv region revealed that the concentrations of metals such as cobalt, cadmium, lead, nickel, chromium, copper, zinc, manganese, molybdenum, arsenic, and mercury are within acceptable limits. The findings confirm that water quality complies with ecological standards and is safe for consumption. The study’s results enable the development of effective water resource management strategies aimed at reducing the risks of heavy metal pollution and ensuring ecological safety. Regular monitoring allows for timely detection of changes in water bodies and helps prevent potential threats to human health and ecosystems. This indicates a stable ecological state of the region’s water resources. The water is suitable for use without the immediate need for reducing the concentrations of these metals.
