The article studies the ecological state of Lake Alakol and other objects of the Zhetysu region. The purpose of the research work is to study the level of heavy metal pollution of the components of the biosphere of Lake Alakol. During the research work, the concentrations of heavy metals in the main components of the biosphere (air, water, soil) of Lake Alakol and other objects of the Zhetysu region were determined.The level of heavy metal pollution of surface waters, soils of Lake Alakol and other objects was studied.Analysis of the content of heavy metals in surface water samples from the coastal areas of Lake Alakol shows that the concentration of cadmium in its maximum permissible concentration is 7-12 times higher. Analysis of the content of heavy metals shows in the soil samples of the Yrgaity River that the concentration of cobalt exceeds the maximum permissible concentration by 2.9 times. The values obtained during the study necessitated the study of the state of the main components of the biosphere.
