The study provides a detailed examination of the toxicological effects of cadmium (Cd) exposure, which continues to be a significant global health concern. It describes how cadmium, found in various environmental sources such as air, water, soil, and food, poses serious health risks. These risks include damage to multiple organ systems like the skeletal, urinary, cardiovascular, reproductive, and nervous systems, and can lead to long-term diseases such as cancer. The review further explores modern treatments for cadmium poisoning, such as chelation therapies, including both traditional and innovative nanoparticle-based methods. Additionally, it discusses the need for cadmium detection in food and environmental products, urging the implementation of public health strategies to reduce exposure and prevent poisoning.
Who is affected?
The stakeholders most affected by cadmium toxicity include individuals living in areas with high levels of environmental contamination, such as regions near industrial sites involved in the production of nickel-cadmium batteries, electroplating, and other cadmium-emitting processes. Farmers and food producers, especially those cultivating rice and seafood, are at risk due to contamination from cadmium in the soil. Particularly vulnerable populations include smokers, children, pregnant women, and workers in industries that use or release cadmium. Public health officials, food safety regulators, and certification bodies are also key stakeholders who must monitor and enforce cadmium exposure limits to protect public health.
Most important findings
The document highlights several crucial aspects of cadmium exposure and its health consequences. Cadmium contamination primarily occurs through food, industrial emissions, and tobacco smoke, with rice and seafood identified as major dietary sources. Long-term exposure to cadmium can lead to severe health conditions, including kidney damage, bone diseases like Itai-itai disease, reproductive toxicity, cardiovascular issues, and an increased risk of cancers, particularly lung and renal cancers.
Despite some reductions in exposure in certain countries, the compound’s long biological half-life (up to 30 years) remains a serious concern. However, studies show that some regions exceed these levels, posing additional risks to public health. In terms of treatment, new developments in chelation therapies, such as using nanoparticles, have shown promise in removing cadmium from the body. Moreover, monitoring cadmium levels in biological samples like blood, urine, hair, and nails is critical for early detection of poisoning.
Key implications
For the food industry, the implications are significant, particularly in areas with high environmental cadmium exposure. Manufacturers must adopt stringent monitoring and control measures to ensure that cadmium levels in food products do not exceed the regulatory limits. Public health initiatives will be vital to mitigate exposure risks, particularly in at-risk populations. Additionally, regulatory bodies will likely refine their guidelines and enforcement mechanisms in the future, aligning with emerging scientific data on cadmium’s toxicity. These measures will require ongoing collaboration between food manufacturers, public health officials, and regulatory agencies to prevent cadmium poisoning and protect consumer health.
Cadmium is a persistent heavy metal that accumulates in kidneys and bones. Dietary sources include cereals, cocoa, shellfish and vegetables, while smokers and industrial workers receive higher exposures. Studies link cadmium to kidney dysfunction, bone fractures and cancer.
