Cadmium toxicity occurs when the body is exposed to high levels of cadmium, a heavy metal found in industrial processes, batteries, and some fertilizers. It can enter the body through inhalation, ingestion, or skin contact, leading to harmful effects on various organs, particularly the kidneys and lungs. Symptoms of cadmium toxicity may include nausea, vomiting, abdominal pain, and respiratory issues. Long-term exposure can result in more severe health problems, such as bone fragility and increased risk of cancer. Preventive measures include reducing exposure in workplaces and monitoring environmental levels of cadmium.
