Cadmium is a toxic metal that can be found in the environment, including in food, water, and air. Exposure to cadmium can occur through various sources, such as smoking, industrial activities, and contaminated food and water.

The health effects of cadmium exposure depend on the level and duration of exposure, as well as individual factors such as age, gender, and health status. Cadmium exposure has been linked to kidney damage, lung damage, and an increased risk of cancer.

The webpage provides information on biomonitoring, which is the measurement of cadmium levels in biological samples such as blood, urine, and hair. Biomonitoring can help assess the extent of cadmium exposure in a population and inform public health interventions.
