The US Department of Health and Human Services and the International Agency for Research on Cancer have determined that cadmium is a known human carcinogen, associated with lung cancer. Additionally, acute and long-term exposures can lead to lung and kidney damage, bone loss, hypertension. In sufficient quantities, cadmium is lethal. Cadmium’s extreme toxicity means that overexposure can occur even when only trace amounts are present, such as during smelting and electroplating activities. https://healthymaterialslab.org/tool-guides/hml-resources
