Research advances in toxicity of uranium in vivo and its new chelators / 中国辐射卫生

Uranium is an important radioactive actinide in nature and an important nuclear material in nuclear industry. After uranium is accidentally released into the environment, it enters the body through the respiratory tract, the digestive tract, and other ways, then enters the circulation system through blood, and is finally mainly deposited in the kidney and bone, causing a certain degree of toxicity. Therefore, efficient low-toxicity chelators are an important way to reduce radionuclide pollution, radiation damage, and chemical toxicity. This article reviews uranium deposition and harm, the detoxification mechanism of uranium chelators, and the research advances in uranium chelators and points out the development trend of uranium chelators.
