Abstract

Clean and safe water is essential for human health and well-being. However, growing human activities are leading to severe water pollution, deteriorating its quality, particularly in big cities. The water quality directly affects aquatic systems, including rivers, lakes and canals, public health and biodiversity. This study aims to explore the ecological characteristics and hydrochemical changes in the water flow of the Bozsuv canal, which is one of the most vital sources of water to Tashkent, the capital city of Uzbekistan. The research highlights the seasonal variations in key chemical indicators such as Calcium (Ca²⁺), Magnesium (Mg²⁺), Nitrite (NO₂⁺), and total hardness (TH) that impact water quality. By analyzing water samples from incoming and outgoing flows of the Bozsuv canal, the study ehibits significant increases in water hardness and pollutant concentrations from March to August, which subsequently decrease towards the end of the year. The results indicate the need for regular monitoring and effective pollution control measures essential to prevent further deterioration and to ensure the sustainability of water resources.
