毒害物質數據：7440-02-0(Hazardous Substances Data)

毒性：Occupational exposures may occur in its mining, smelting, and refining. The general population ingests nickel in food. Skin sensitization and dermatitis leading to chronic eczema, called “nickel itch," frequently occurs, especially in wearers of pierced earrings. Nickel can also irritate the conjunctiva and respiratory tract mucous membranes. Absorption from the digestive tract is poor, so systemic poisoning is rare, but since it is an irritant it acts as an emetic. Systemic effects include hyperglycemia, capillary damage, CNS depression, myocardial weakness, and kidney damage. Nickel and its compounds are carcinogenic following inhalation, but not following ingestion or skin contact. Cancer of the lung and nasal passages results, with a latent period of about 25 years; smokers are at greater risk. In addition to irritation and carcinogenesis, nickel carbonyl (nickel tetracarbonyl, Ni(CO)4) exerts relatively mild, tran_x0002_sientinitial symptoms including headache, giddiness, nausea, and shortness of breath. These symptoms are followed by very serious symptoms hours to days later, consisting of tightness in the chest, shortness of breath, rapid respiration, pulmonary edema, cyanosis, and extreme weakness; this can be fatal. Heat decomposition of nickel carbonyl yields carbon monoxide. Chelating agents can be used to remove nickel from the body.
