Selenium (Selenium) is an essential trace element widely found in nature and involved in various biological metabolic processes. However, when selenium concentrations are too high, they can cause severe toxic effects on humans, animals, and the environment. Industrial activities, especially coal combustion in coal-fired power plants, are one of the...
