A review on Cadmium Exposure in the Population and Intervention Strategies Against Cadmium Toxicity

The rapid industrial development has led to serious cadmium (Cd) pollution. Cd is a toxic heavy metal placing severe health threat to human. Cd can enter the body through the atmosphere, water, soil and food, and has a long half-life (10–30 years), it largely accumulates in kidneys, liver, bone and other organs and causes irreversible damage to the target organs. Cd pollution has also further caused certain carcinogenic and non-carcinogenic health risk. This study summarizes the current situation of Cd pollution, the toxicity of specific target organs, carcinogenic risk and non-carcinogenic risk in the general population, as well as dietary supplements to prevent and mitigate Cd toxication, which aims to focus on the adverse effects of Cd to human from both individual and population perspectives, hoping that not only the health risk of Cd poisoning can be reduced, but also the accurate prevention and control of Cd poisoning can be achieved in the future.
