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, leading to serious health issues such as kidney damage and bone fragility. Due to its toxicity, the use of cadmium is regulated in many countries. It is often found in industrial waste and can contaminate soil and water, affecting both the environment and human health. Safe handling and disposal practices are essential to minimize its impact.
