Nickel is a very abundant natural element. Pure nickel is a hard, silvery-white metal. Nickel can be combined with other metals, such as iron, copper, chromium, and zinc, to form alloys. These alloys are used to make coins, jewelry, and items such as valves and heat exchangers. Most nickel is used to make stainless steel. Nickel can combine with other elements such as chlorine, sulfur, and oxygen to form nickel compounds. Many nickel compounds dissolve fairly easy in water and have a green color. Nickel compounds are used for nickel plating, to color ceramics, to make some batteries, and as substances known as catalysts that increase the rate of chemical reactions. Nickel is found in all soil and is emitted from volcanoes. Nickel is also found in meteorites and on the ocean floor. Nickel and its compounds have no characteristic odor or taste.

Nickel occurs naturally in the environment at low levels. Nickel is an essential element in some animal species, and it has been suggested it may be essential for human nutrition. Nickel dermatitis, consisting of itching of the fingers, hands, and forearms, is the most common effect in humans from chronic (long-term) skin contact with nickel. Respiratory effects have also been reported in humans from inhalation exposure to nickel. Human and animal studies have reported an increased risk of lung and nasal cancers from exposure to nickel refinery dusts and nickel subsulfide. Animal studies of soluble nickel compounds (i.e., nickel carbonyl) have reported lung tumors. EPA has classified nickel refinery dust and nickel subsulfide as Group A, human carcinogens, and nickel carbonyl as a Group B2, probable human carcinogen.

Nickel carbonyl can cause acute pneumonitis. [Hendrick, p. 180] Asthma: metal plating; [Malo] Most OA cases caused by nickel were single case reports. [Asthma in the Workplace, p. 297] Allergic contact dermatitis: electronics workers, hairdressers, housekeeping personnel, textile workers, and machinists; [Marks] About one half of nickel produced is used in stainless steel alloys. Sulfur-rich stainless steels are more likely to react with sweat, be absorbed in the skin, and cause sensitization. The prevalence of nickel skin allergy is higher in women (up to 17%) than in men (up to 3%) because of greater exposure to ear piercing and cheap jewelry. Allergic contact dermatitis (ACD) has been reported in electroplaters, battery workers, electronics workers, machinists, hairdressers, mechanics, and construction workers. ACD has also been reported in a bank clerk, a bartender, an engraver, a potter, and in tailors, offset printers, butchers, and musicians. The dimethylglyoxime test (Fisher's test) can detect nickel release from tools and jewelry. [Kanerva, p. 485-92] Nickel causes contact urticaria; [Kanerva, p. 219] In high-dose animal studies, nickel and nickel carbonyl cause birth defects. [Frazier] The relevance of a positive patch test to occupational contact dermatitis (OCD) is difficult to evaluate in most cases. Nickel is not considered relevant in about 64% of OCD cases. [See Reference #1] Nickel is hepatotoxic. [Nordberg, p. 1099] Elemental nickel and nickel alloys are possible human carcinogens; nickel compounds are known human carcinogens. The highest risks were found in calcining workers heavily exposed to nickel oxides and sulfides. Soluble nickel (nickel sulfate) was associated with increased risks in hydrometallurgy workers. [IARC] Nickel elemental = A5; Soluble inorganic compounds = A4; Insoluble inorganic compounds = A1; Nickel subsulfide = A1; Increased risk of lung and nasal sinus cancer in nickel refinery workers exposed to >1 mg Ni/m3 (soluble nickel) and >10 mg/m3 (insoluble nickel); [ACGIH] Metallic nickel is listed as anticipated and nickel compounds are listed as known human carcinogens. Several cohort studies of workers exposed to various nickel compounds showed an elevated risk of death from lung cancer and nasal cancer. Although the precise nickel compound responsible for the carcinogenic effects in humans is not always clear, studies indicate that nickel sulfate and combinations of nickel sulfides and oxides encountered in nickel refining industries cause cancer in humans.

Nickel is a ubiquitous trace metal and occurs in soil, water, air and the biosphere. Nickel ore deposits are accumulations of nickel sulfide minerals (mostly pentlandite) and laterites. Most nickel is used for production of stainless steel and other nickel alloys with high corrosion and temperature resistance. Nickel levels in terrestrial and aquatic organisms can vary over several orders of magnitude. Dermal exposure in the general environment is important for the induction and maintenance of contact hypersensitivity caused by daily contact with nickel plated objects or nickel containing alloys (e.g. jewellery, coins or clips). Iatrogenic exposure to nickel results from implants and prostheses made from nickel containing alloys, from iv or dialysis fluids and from radiographic contrast media. In the working environment, airborne nickel concentrations can vary from a few microgram/cu m to a few mg/cu m, depending upon the process involved and the nickel content of the material being handled. Workers are exposed to nickel containing dusts and fumes during welding, plating, grinding, mining, nickel refining, and in steel plants. Dermal exposure to nickel may occur in a wide range of jobs, either by direct exposure, dissolved nickel in refining, electroplating and electroforming industries or by handling nickel containing materials. Nickel can be absorbed in human beings and animals via inhalation or ingestion or percutaneously. Respiratory absorption with secondary gastrointestinal absorption (insoluble and soluble) is a major route of entry during occupational exposure. Percutaneous absorption is negligible, quantatively, but is important in the pathogenesis of contact hypersensitivity. Nickel is transported in the blood, principally bound to albumin. Gastrointestinal absorption of nickel is variable and depends on the composition of the diet. All body secretions are potential routes of excretion including the urine, bile, sweat, tears, milk and mucociliary fluid. Non-absorbed nicke is eliminated in the feces. Data on nickel excretion suggest a two compartment model. Nickel concentration in the serum and urine of healthy non-occupationally exposed adults are 0.2 ug/l (range: 0.05-1.1 ug/l) and 1.5 ug creatinine (range: 0.5-4.0 mg/g creatinine, respectively. The body burden of nickel in non-exposed 70 kg adult is 0.5 ug. Nickel is essential for the catalytic activity of some plant and bacterial enzymes. Slow weight gain, anemia and decreased viability has been described in some animal species after dietary deprivation of nickel. Contact allergy to nickel is very common in human beings; experimental sensitization in animals is only successful under special conditions. Longterm inhalation exposure to metallic nickel caused mucosal damage and inflammatory reaction, sometimes accompanied by slight fibrosis, was observed in rabbits after high level exposure to nickel graphite dust. Metallic nickel induced local mesenchymal tumors in a variety of experimental animals after im, sc, intraosseous, intrarenal, intra-articular, pleural, intraocular, intratesticular or intra-adipose administrtation. Metallic nickel has been tested for carcinogenicity by parenteral routes of administration, local tumors were noted. In studies using repeated intratracheal instillation, nickel powder caused respiratory tumors. Chronic effects such as rhinitis, sinusitis, nasal septal perforations and asthma have been reported in nickel refinery and nickel plating workers. Some researchers reported pulmonary changes with fibrosis in workers handling nickel dust. Orsal nickel intake may aggravate vesicular hand eczema. Prostheses or other surgical implants make with nickel containing alloys have been reported to cause nickel sensitization. Cancer rates have generally been close to normal in stainless steel welding and nickel using industries, with the exception of those involving exposure to chromium, particularly electroplating. Nickel/cadmium battery workers exposed to high levels of both nickel and cadmium may have resulted in a slightly increased risk of lung cancer. Excesses of various cancers other than lung and nasal cancers such as renal, gastric or prostatic have occasionally been reported in nickel workers, but none have been found consistently. No increased cancer risk has been demonstrated in workers exposed exclusively to metallic nickel. The combined data on nickel alloy workers and gasseous diffusion workers, all of whom were exposed to average concentrations of the order of 0.5 mg nickel/cu m show no excess risk, though the total number of lung cancers in these cohorts was to small to exclude a small increase in risk at this level.

Nickel is hepatotoxic in animals and has been shown to effect renal function in man. It binds to the anionic glycosaminoglycan sites of the glomerular basement membrane. Ionic blocking of these sites leads to the loss of selectivity in the filtration of albumin and may explain the proteinuria associated with nickel exposure.
