Cadmium is a soft, bluish-white metal that is part of the transition metals group in the periodic table. It is known for its malleability and resistance to corrosion, making it useful in various applications, including batteries, pigments, and coatings. However, cadmium is toxic and can pose health risks if ingested or inhaled. This metal is primarily obtained from zinc ores and is often released into the environment through industrial processes. Due to its harmful effects, regulations have been established to limit cadmium exposure in products and workplaces, ensuring safety for both humans and the environment.
