However, because it is unknown whether the test was according to the guideline, and there is no other information, it was classified as "Classification not possible." | FY2013 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0)) |
4 | Respiratory sensitization | Category 1 |
Danger |
H334 | P304+P340 P342+P311 P261 P284 P501 |
In the Initial Risk Assessment Report (NITE, CERI, NEDO, 2008), there is a report on cases developing asthma for nickel sulfate, although the number is small. Nikel and inorganic nickel compounds are classified in occupational sensitizers to the airway Group 2 in the Recommendation of Occupational Exposure Limits (Japan Society For Occupational Health (JSOH), 2013), "R42" in EU DSD classification, and "Resp. Sens. 1 H334" in EU CLP classification. From the above, it was classified in Category 1. | FY2013 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0)) |
4 | Skin sensitization | Category 1 |
Warning |
H317 | P302+P352 P333+P313 P362+P364 P261 P272 P280 P321 P501 |
Multiple results of maximization tests with guinea pigs, etc. are described in the Initial Risk Assessment Report (NITE, CERI, NEDO, 2008), and all of them showed sensitization and gave positive results. Also, in epidemiological surveys or case reports in humans, multiple positive results are mentioned. Nickel and inorganic nickel compounds are classified in occupational skin sensitizers Group 1 in the Recommendation of Occupational Exposure Limits (Japan Society For Occupational Health (JSOH), 2013), "R43" in EU DSD classification, and "Skin Sens. 1 H317" in EU CLP classification. From the above, it was classified in Category 1. | FY2013 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0)) |
5 | Germ cell mutagenicity | Classification not possible |
- |
- | - | It was classified as "Classification not possible" because it was not possible to classify a substance as "Not classified" according to the revised GHS classification guidance for the Japanese government. It is reported that nickel sulfate hexahydrate was negative in a micronucleus test with mouse bone marrow (Mutat. Res., 1997). In the literature, all of nickel sulfate hexahydrate, nickel chloride hexahydrate, and nickel oxide (III) were negative in micronucleus tests. As in vivo test data on nickel sulfate (unknown whether it is the anhydrate or hexahydrate), it was reported to be negative in a chromosomal aberration test with rat spermatogonial cells, micronucleus tests with bone marrow cells of rats and mice, and a chromosomal aberration test with rat bone marrow cells (Initial Risk Assessment Report (NITE, CERI, NEDO, 2008), ATSDR (2005)). On the other hand, there are positive results in a micronucleus test with mice and DNA damage tests with mice and rats (Initial Risk Assessment Report (NITE, CERI, NEDO, 2008)), but they were not assessed in ATSDR (2005). As for in vitro tests, data for that this substance could be specified are limited to a negative result in a bacterial reverse mutation test and a positive result in a gene mutation test with cultured mammalian cells (NTP DB (Access on August 2013)). Nickel sulfate (unknown whether it is the anhydrate or hexahydrate) was negative in a bacterial reverse mutation test and positive in a chromosomal aberration test and a gene mutation test with cultured mammalian cells (Initial Risk Assessment Report (NITE, CERI, NEDO, 2008), ECETOC TR 33 (1989), ATSDR (2005)). From the above, from in vitro test data, it is judged to be positive, but because negative results are indicated in in-vivo tests, it was classified as "Classification not possible." Besides, nickel sulfate (CAS RN 7786-81-4) was classified as "Not classified." | FY2013 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0)) |
6 | Carcinogenicity | Category 1A |
Danger |
H350 | P308+P313 P201 P202 P280 P405 P501 |
Nickel sulfate, the anhydrate of this substance, are classified in Group 1 as nickel compounds by IARC (IARC (2012)), "Carc. Cat. 1; R45" in EU DSD classification, "Carc.1A H350i" in EU CLP classification, Group 2B by the Japan Society for Occupational Health (JSOH) (Recommendation of Occupational Exposure Limits (Japan Society For Occupational Health, 2013)), K by NTP (NTP (2002)), and A4 as soluble nickel compounds by ACGIH (ACGIH (1996)). Besides, it is described in NTP TR454 (1996) that there was no tumor increase in both 2-year inhalation tests with rats and mice. Among the above information, by giving priority to the year issued, the classification in IARC (2012) was adopted, and it was classified in Category 1A. | FY2013 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0)) |
7 | Reproductive toxicity | Classification not possible |
- |
- | - | Classification not possible due to lack of data. Besides, in a two-generation reproductive toxicity test and a three-generation reproductive toxicity test with rats in the oral route (gavage), no effects on reproductive and developmental toxicity were observed (Initial Risk Assessment Report (NITE, CERI, NEDO, 2008)). However, because no sufficient data on teratogenicity were obtained, it was classified as "Classification not possible" due to lack of data. | FY2013 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0)) |
8 | Specific target organ toxicity - Single exposure | Classification not possible |
- |
- | - | Classification not possible due to lack of data. Besides, in the case of a two-and-a-half-year-old girl who accidentally ingested 5 g of nickel sulfate anhydrate, she had a cardiac arrest after 4 hours and died after 8 hours. Pathology examination revealed irritative changes in the gastrointestinal tract (Initial Risk Assessment Report (NITE, CERI, NEDO, 2008), ECETOC TR 33 (1989)). | FY2013 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0)) |

H372 H373 |
P260 P264 P270 P314 P501 |
In 90-day administration tests (drinking water or gavage) with rats and a 2-year gavage administration test with rats, reduced weight gain, increased mortality, weight changes in a part of organs such as the kidney were observed at the doses (15-30 mg/kg/day) within the guidance value range for Category 2, but no organs showed histopathological changes (Initial Risk Assessment Report (NITE, CERI, NEDO, 2008)). Furthermore, it is described that in 90-day or 2-year inhalation exposure test with rats or mice, inflammatory changes in the lung and bronchus, atrophy of the olfactory epithelium, etc. were found from the concentrations (converted guidance value: 0.0002 mg/L or below) within the range for Category 1 (Initial Risk Assessment Report (NITE, CERI, NEDO, 2008), NTP TR454 (1996), ACGIH (7th, 2001)), therefore it was classified in Category 1 (respiratory organs). Moreover, in a 30-day dermal exposure test with rats, other than changes in the skin at the application site, toxicity changes were observed in the liver (enlargement of hepatocytes, partial necrosis of the liver, swelling and congestion of the sinusoid) and testis (edema and degeneration in the seminiferous tubules) at the doses (converted guidance value: 20-30 mg/kg/day) corresponding to Category 2 (Initial Risk Assessment Report (NITE, CERI, NEDO, 2008)). From the above, Category 1 (respiratory organs), Category 2 (liver, testis). | FY2013 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0)) |
