Nickel and its compounds are categorized as respiratory tract sensitizers (Group 2) in Recommendations of Occupational Exposure Limits (Japan Society for Occupational Health, 2008). Similarly, they are rated as respiratory tract sensitizers by the DFG (MAK/BAT No. 43 (2007)). Based on these ratings, the substance was classified into Category 1. | |

Soluble nickel is classified into skin sensitizers by ACGIH (ACGIH-TLV (2008)). In addition, Nickel and its compounds are categorized into skin sensitizers (Group 1) in Recommendations of Occupational Exposure Limits (Japan Society for Occupational Health, 2008). Similarly, Nickel and its compounds are rated as skin sensitizers by the DFG (MAK/BAT No. 43 (2007)). Based on these ratings, the substance was classified into Category 1. | |
5 | Germ cell mutagenicity | Classification not possible | - | - | - | - | Classification is not possible due to lack of in vivo test results and in vitro mutagenicity test results using several indices. Regarding in vitro mutagenicity tests, chromosomal aberration tests using mouse mammary carcinoma Fm3A cells produced positive results (IARC vol. 49, 1990). |

No test results on this substance are available. However, since soluble inorganic nickel compounds are documented to be respiratory tract irritants according to ACGIH-TLV (2004) and ACGIH (7th, 2001), the substance was classified into Category 3 (respiratory tract irritation). See also health hazards associated with other nickel compounds (Nickel(II) chloride and nickel sulfate, etc.). | |

No test results on this substance are available. However, since soluble inorganic nickel compounds are documented to affect the central nervous system (ACGIH TLV-basis critical effects: central nervous system; ACGIH-TLV (2004)), the substance was classified into Category 1 (central nervous system). See also health hazards associated with other nickel compounds (Nickel(II) chloride and nickel sulfate, etc.). | |
