|---|---|---|---|---|---|---|
| 1 | Acute toxicity (Oral) | Classification not possible |
- |
- | - | Classification not possible due to lack of data. Besides, although an LD50 value of 1,790 mg/kg (Environmental Risk Assessment for Chemical Substances Vol.8 (Ministry of the Environment, 2010)) for rats is reported. However, because this data is originally from RTECS, which is listed in List 3 and the original document is private communication, it was not used for classification. |

According to the Recommendation of Occupational Exposure Limits (Japan Society For Occupational Health (JSOH), 2016), chromium and chromium compounds are classified in Group 2 of occupational airway sensitizers, and this corresponds to Category 1A according to the GHS classification guidance for the Japanese Government. However, in the above recommendation, chromium and chromium compounds were newly classified in Group 2 of occupational airway sensitizers as a substance which sensitization has not clarified yet through epidemiologic research, based on the classification standard for sensitization (provisional, May 26, 2010). Therefore, it was judged as inappropriate to classify this substance in Category 1A and it was classified in Category 1B. |
| 4 | Skin sensitization | Category 1A |

According to the Recommendation of Occupational Exposure Limits (Japan Society For Occupational Health (JSOH), 2016), chromium and chromium compounds are designated in Group 1 of occupational skin sensitizers. Moreover, in skin sensitization tests using guinea pigs, positive results were obtained in 2 modified maximization tests, and in one of these tests, the sensitization ratio was 77% after the intradermal injection at a dose of 0.91% (CICAD 76 (2009)). In addition, it is reported that the workers who developed contact dermatitis at several factories handling chromium compounds showed positive reactions with trivalent and hexavalent chromium compounds including this substance in patch tests (ATSDR (2012)). From the above, this substance was classified in Category 1A. |
| 5 | Germ cell mutagenicity | Classification not possible |
- |
- | - | As for in vivo data, the result was negative in a micronucleus test using mouse bone marrow cells, and negative in DNA damage tests (DNA strand breaks) using the liver or kidneys in rats (CICAD 76 (2009), ATSDR (2012)). As for in vitro data, almost all the results were negative in bacterial reverse mutation tests; using cultured mammalian cells, negative in a mouse lymphoma assay, positive in a micronucleus test, negative and positive results in chromosomal aberration tests, and negative in many of sister chromatid exchange tests have been reported (CICAD 76 (2009), ATSDR (2012)). From the above, this substance was classified as "Classification not possible" due to the GHS classification guidance for the Japanese Government. |
| 6 | Carcinogenicity | Classification not possible |
- |
- | - | As for trivalent chromium compounds, IARC classified them in Group 3 (IARC 49 (1990)), ACGIH classified them in A4 (ACGIH (7th, 2001)), and EPA classified them in Group D (IRIS (1998)) respectively. Therefore, this substance was classified as "Classification not possible" for this hazard class. |

In a test in which mice were given this substance in drinking water for 12 weeks, fertility was evaluated for each sex. At the high dose (5,000 mg/L) at which water consumption was reduced, a decrease in the number of pregnant females was observed when treated males were mated with untreated females, and a decrease in the number of implantations and viable fetuses was observed when treated females were mated with untreated males (CICAD 76 (2009)). In addition, 1,000 mg/L of this substance was administered to pregnant mice in drinking-water from Day 12 of pregnancy to the weaning of the pups, and the effect on the reproductive ability of the pups was examined. As a result of mating between untreated females and dosed males, there was no effect on the fertility, but in the mating between dosed females and untreated males, the number of pregnant females decreased and the number of resorptions increased (F1 pups showed effects such as decreased weight gain and delayed time of vaginal opening during the growth process) (CICAD 76 (2009). On the other hand, when male rats were treated with 1,000 mg/L of this substance in drinking-water for 12 weeks and mated with untreated females, no difference from the control group was seen in the number of pregnant females, the number of implantations, or the number of viable fetuses (CICAD 76 (2009)). As described above, in male and female mice, decreased fertility and fetal toxicity were observed both at doses at which general toxicity was not evident, but since no effect on the insemination ability of male rats was observed, it was judged reasonable to classify this substance in Category 2 for this hazard class. |

From 96-hour EC50 = 0.4 mg/L for algae (Pseudokirchneriella subcapitata) (CICADs 76, 2009), it was classified in Category 1. |

If chronic toxicity data are used, then it is classified in Category 2 due to unknown environmental dynamics of the inorganic compound, and 21-day NOEC (reproduction) = 0.7 mg/L for crustacea (Daphnia magna) (CICADs 76, 2009). If acute toxicity data are used for a trophic level for which chronic toxicity data are not obtained, then it is classified in Category 1 due to unknown environmental dynamics of the inorganic compound, and 96-hour EC50 = 0.4 mg/L for algae (Pseudokirchneriella subcapitata) (CICADs 76, 2009). It was classified in Category 1 by drawing a comparison between the above results. |
