- Toxicity Summary: ... Nickel carbonate is insoluble in water. ... Respiratory absorption with secondary gastrointestinal absorption of nickel (insoluble compounds) is the major route of entry during occupational exposure. Percutaneous absorption is negligible, quanitatively, but is important in the pathogenesis of contact hypersensitivity. Absorption is related to the solubility of the compound /and nickel carbonate is classified as an insoluble salt/. Nickel carbonate ... induced local mesenchymal tumors in a variety of experimental animals after im, sc, ip, intrapleural, intraocular, intraosseous, intrarenal, intra-articular, intratesticular or intra-adipose administration.

Nickel carbonate
Nickel Carbonate is a light green, crystalline inorganic compound that produces toxic gases upon heating. Nickel carbonate is used in electroplating, to prepare nickel monoxide, to make colored glass and as a catalyst in the treatment of wastewater. Exposure to this substance can cause severe dermatitis, skin and asthma-like allergies and affects the lungs, kidneys, gastrointestinal tract and neurological system. Nickel carbonate is a known carcinogen and is associated with an increased risk of developing lung and nasal cancers. (NCI05) — NCI Thesaurus (NCIt)
