OverviewHeavy metals play a significant and multifaceted role in the pathogenicity of microbial species. Their involvement can be viewed from two primary perspectives: the toxicity of heavy metals to microbes and the exploitation of heavy metals by microbial pathogens to establish infections and evade the host immune response. Understanding these aspects is critical for both […]

What was studied?
The study focuses on cadmium (Cd), a toxic metal that can accumulate in the human body and cause various health issues. It examines how Cd exposure occurs, primarily through inhalation and ingestion, and the subsequent toxic effects it has on the body. The review explores the role of cadmium in chronic diseases, including lung diseases, kidney damage, bone demineralization, and neurological disorders, and it highlights how the metal accumulates over time, especially in high-risk populations like smokers and workers in the metal industry.
Who was studied?
The review addresses the human population exposed to cadmium, particularly those at higher risk, such as workers in the metallurgical industry and individuals who smoke. It also focuses on the general population, discussing exposure through environmental sources like contaminated food and air. The paper highlights how cadmium accumulates in various tissues, especially the lungs, kidneys, and bones, and emphasizes the need for continuous monitoring of at-risk individuals.
Most important findings
Cadmium is primarily absorbed through the respiratory and digestive systems, with 13–19% absorbed via inhalation and 10–44% through ingestion. The accumulation of cadmium in human tissues, particularly the kidneys, lungs, and bones, can lead to long-term health problems. Its biological half-life ranges from 16 to 30 years, meaning it can remain in the body for decades. Chronic exposure to cadmium is linked to a wide range of health issues, including lung diseases, kidney damage, osteoporosis, cardiovascular problems, and neurological disorders. Exposure to cadmium also plays a role in cancer development, particularly lung, prostate, and breast cancer, through mechanisms like oxidative stress and DNA damage.
Key implications
The findings underscore the importance of continuous monitoring for individuals exposed to cadmium, especially those in high-risk groups. Chronic exposure, even at low levels, can cause significant health problems, and the study calls for improved preventive measures, such as stricter occupational safety regulations and dietary interventions. It also stresses the importance of reducing cadmium exposure through public health initiatives and environmental policies aimed at controlling pollution from industrial activities.
Cadmiun (Cd)
Cadmium (Cd) is a highly toxic heavy metal commonly found in industrial, agricultural, and environmental settings. Exposure to cadmium can occur through contaminated water, food, soil, and air, and it has been linked to a variety of health issues, including kidney damage, osteoporosis, and cancer. In agriculture, cadmium is often present in phosphate fertilizers and can accumulate in plants, entering the food chain. Its toxicity to living organisms makes cadmium a subject of regulatory concern worldwide, particularly in industrial waste disposal and environmental monitoring.
