Cadmium is a naturally occurring toxic metal with common exposure in industrial workplaces, plant soils, and from smoking. Like all heavy metals, it accumulates in the bodies of most organisms (including humans). Poisoning may result from the ingestion of an acid food or drink prepared in a cadmium-lined vessel (e.g., lemonade served from cadmium-plated cans).Nausea, vomiting, diarrhea, and prostration usually occur within 15 minutes after ingestion and subside within 24 hours. Cadmium Toxicity And Its Phytoremediation A Review . The risk to humans is high due to consumption of cadmium-contaminated food. In the workplace, people are exposed where cadmium is used or generated, such as in battery manufacturing, metal soldering, or welding. or beverage containers.

Metals differ from other pollutants in that they are neither created nor destroyed and occur naturally in the environment. Cadmium releases can be carried to and deposited on areas remote from the sources of emission by means of long-range atmospheric transport. Anthropogenic activity largely contributes to human exposure because metals are bioconcentrated from the environment through mining activities or through processes occurring at various industrial settings.
