Anhydrous nickel sulfate is a yellow-green crystalline solid. Nickel sulfate can also be obtained as a hexahydrate (NiSO4.6H2O (CAS: 10101-97-0) which is blue to emerald green, and as a heptahydrate (NiSO4.7H2O) (CAS: 10101-98-1) , which is green. Samples can contain variable quantities of water, depending on their previous exposure to moisture or conditions. All forms are mildly toxic and are carcinogenic. All are denser than water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Used to make other nickel compounds, in printing, and in dyeing of textiles.

Storage site should be as close as practical to lab in which carcinogens are to be used, so that only small quantities required for expt need to be carried. Carcinogens should be kept in only one section of cupboard, an explosion-proof refrigerator or freezer (depending on chemicophysical properties ) that bears appropriate label. An inventory should be kept, showing quantity of carcinogen & date it was acquired Facilities for dispensing should be contiguous to storage area.

Listed as a hazardous air pollutant (HAP) generally known or suspected to cause serious health problems. The Clean Air Act, as amended in 1990, directs EPA to set standards requiring major sources to sharply reduce routine emissions of toxic pollutants. EPA is required to establish and phase in specific performance based standards for all air emission sources that emit one or more of the listed pollutants. Nickel sulfate is included on this list.

Persons in charge of vessels or facilities are required to notify the National Response Center (NRC) immediately, when there is a release of this designated hazardous substance, in an amount equal to or greater than its reportable quantity of 100 lb or 45.4 kg. The toll free number of the NRC is (800) 424-8802; In the Washington D.C. metropolitan area (202) 426-2675. The rule for determining when notification is required is stated in 40 CFR 302.4 (section IV. D.3.b).

The hamster embryo cell bioassay was used to study the effect of metal salts on morphological transformation. A synergistic enhancement of the transformation frequency was found for the combined treatment with organic carcinogens (benzo(a)pyrene (b(a)p), N-hydroxy-2-acetylaminofluorene and 4-nitroquinoline-1-oxide) and nickel sulfate. The synergistic effect between b(a)p and nickel sulfate was apparent when the cells were treated sequentially with the chemicals. When the cells were first exposed to b(a)p, nickel sulfate showed a promotion-like effect, similar to that obtained with the tumor promoter 12-O-tetradecanoylphorbol-13-acetate (12-O-tpa). When 12-O-tpa or b(a)p were used as promoters nickel sulfate was able to initiate morphological transformation. The metal salts are more potent as promoters than they are as initiators in this assay.|The effect of unfractionated heparin and a low molecular weight heparin fragment on the DNA synthesis response of human peripheral blood T lymphocytes from nickel-allergic patients, activated by mercuric chloride and nickel sulfate was tested. Inhibition was found with 1.1 mg/ml unfractionated heparin added 1 hr after mercuric chloride and nickel sulfate and with the same concentration of the heparin fragment, added 1 hr after nickel sulfate; no effect was seen after at 72 hr. Both heparin preparations in concentrations of 0.0001-0.11 mg/ml stimulated the response to nickel sulfate and in concentrations of 0.001-0.11 mg/ml stimulated the response to mercuric chloride. Heparin preparations seem to have modulating effects on both nickel and mercury activation of lymphocytes. The effect was dependent on both heparin concentration and the time of addition to the activation process.|Synergistic effects of nickel compounds and benzo(a)pyrene on morphological transformation of SHE cells have been reported ...

Two out of 12 rats in both groups receiving both nickel and the nitrosamine developed nasopharyngeal tumors (1 squamous cell carcinoma, 1 fibrosarcoma, 1 papilloma, 1 "early carcinoma"), while none was seen in the 24 animals treated with the nitrosamine alone, or in the two groups of 12 animals treated with nickel sulfate.

Nickel concentration in serum and whole blood and excretion in urine was assayed at different time intervals before and after ingestion of nickel sulfate in 8 healthy volunteers for 3 days.

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment. INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. IMMEDIATELY call a physician and be prepared to transport the victim to a hospital even if no symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing. INGESTION: Some heavy metals are VERY TOXIC POISONS, especially if their salts are very soluble in water (e.g., lead, chromium, mercury, bismuth, osmium, and arsenic). IMMEDIATELY call a hospital or poison control center and locate activated charcoal, egg whites, or milk in case the medical advisor recommends administering one of them. Also locate Ipecac syrup or a glass of salt water in case the medical advisor recommends inducing vomiting. Usually, this is NOT RECOMMENDED outside of a physician's care. If advice from a physician is not readily available and the victim is conscious and not convulsing, give the victim a glass of activated charcoal slurry in water or, if this is not available, a glass of milk, or beaten egg whites and IMMEDIATELY transport victim to a hospital. If the victim is convulsing or unconscious, do not give anything by mouth, assure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. OTHER: Since this chemical is a known or suspected carcinogen you should contact a physician for advice regarding the possible long term health effects and potential recommendation for medical monitoring. Recommendations from the physician will depend upon the specific compound, its chemical, physical and toxicity properties, the exposure level, length of exposure, and the route of exposure.

Cultures of normal human bronchial epithelial cells were continuously exposed to a dose (5-20 micrograms/ml) of nickel sulfate (NiSO4) that reduced their colony forming efficiency by 30-80%. After 40 days of incubation, the cultures consisted of large, squamous cells; mitotic cells were not observed. The cells were then maintained in medium without NiSO4. After 40-75 total days of incubation, colonies of mitotic cells appeared at a rate of 1 colony per 100,000 cells originally at risk; no colonies appeared in control cultures or in cultures exposed to less than 5 micrograms NiSO4/ml for 90 days. Twelve NiSO4-altered cell cultures isolated from five experiments have been expanded into mass cultures. Most of the cell lines had an increased population doubling potential (greater than 50 divisions). Some exhibit aberrations in the squamous (terminal) differentiation process, whereas others lost the requirement for epidermal growth factor for clonal growth. Aneuploidy and marker chromosomes were also noted. However, none of these NiSO4-altered cell cultures are anchorage independent nor do they produce tumors upon injection into athymic nude mice.|For more Human Toxicity Excerpts (Complete) data for NICKEL SULFATE (16 total), please visit the HSDB record page.
