Rationale for the classification
1 Acute toxicity (Oral) Category 4


Warning
H302 P301+P312
P264
P270
P330
P501
From a reported LD50 value of 680 mg/kg for rats (Result of the initial environmental risk assessment of chemicals, Vol. 10, Ministry of the Environment in Japan (2012)), it was classified in Category 4.
1 Acute toxicity (Dermal) Classification not possible
-
-
- - Due to lack of data, the classification is not possible.
1 Acute toxicity (Inhalation: Gases) Not applicable
-
-
- - "Solids" according to GHS definition.
1 Acute toxicity (Inhalation: Vapours) Not applicable
-
-
- - "Solids" according to GHS definition.
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible
-
-
- - Due to lack of data, the classification is not possible.
2 Skin corrosion/irritation Classification not possible
-
-
- - Due to lack of data, the classification is not possible.
3 Serious eye damage/eye irritation Category 2


Warning
H319 P305+P351+P338
P337+P313
P264
P280
From the information that this substance is irritating to animal eyes, it was classified in Category 2 (HSDB (Access on September 2015)).
4 Respiratory sensitization Classification not possible
-
-
- - Due to lack of data, the classification is not possible.
4 Skin sensitization Classification not possible
-
-
- - The classification is not possible due to lack of data. Besides, in an investigation on 787 humans, three cases of skin reaction to a 1% solution of this substance were reported (DFGOT vol. 18 (2002)).
5 Germ cell mutagenicity Classification not possible
-
-
- - As for in vivo, there is the knowledge of a positive dominant lethal test in mice and a positive micronucleus test in mouse bone marrow cells (Result of the initial environmental risk assessment of chemicals, Vol. 10, Ministry of the Environment in Japan (2012); ACGIH (7th, 2003)). As for in vitro, a micronucleus test, a chromosomal aberration test, and a sister chromatid exchange test in human lymphocytes were all positive (Result of the initial environmental risk assessment of chemicals, Vol. 10, Ministry of the Environment in Japan (2012); ACGIH (7th, 2003)).
As a result of confirming the original literature of the above-mentioned in vivo tests, an in vivo test was not conducted on ammonium salt of a molybdic acid (Titenko-Holland et al., 1998). Because the knowledge of these in vivo tests cannot be used, this substance was classified as "Classification not possible" in accordance with Guidance.
6 Carcinogenicity Category 2


Warning
H351 P308+P313
P201
P202
P280
P405
P501
There is no carcinogenicity information on this substance itself. However, as mentioned in this hazard class of sodium molybdate (CAS number: 7631-95-0), ACGIH classified soluble molybdenum compounds in A3 in carcinogenicity assessment based on the carcinogenicity test results using molybdenum trioxide and so on (ACGIH (7th, 2003)). Because this substance corresponds to a soluble molybdenum compound (ACGIH (7th, 2003)), it is thought that the ACGIH's carcinogenicity classification result is applicable. Therefore, the substance was classified in Category 2 in this hazard class.
7 Reproductive toxicity Category 2


Warning
H361 P308+P313
P201
P202
P280
P405
P501
There is no reproductive effect information on this substance in either humans or experimental animals. However, this substance belongs to a soluble molybdenum compound and the classification based on the toxicity information of sodium molybdate (CAS number: 7631-95-0) is possible, and it is considered to be appropriate to apply its classification result. Therefore, this substance was classified in Category 2 in this hazard class.
8 Specific target organ toxicity - Single exposure Category 3 (Respiratory tract irritation)


Warning
H335 P304+P340
P403+P233
P261
P271
P312
P405
P501
Because this substance is irritating to the respiratory tract (DFGOT vol. 18 (2002), ACGIH (7th, 2003)), it was classified in Category 3 (respiratory tract irritation).
9 Specific target organ toxicity - Repeated exposure Category 2 (kidney)


Warning
H373 P260
P314
P501
No human data. As for experimental animals, in a 8-week gavage administration toxicity test using rats, weight gain reduction, decreased absolute kidney weight, increased relative kidney weight, increased urine volume, increased creatinine in urine, decreased creatinine clearance, and increased excretion of urinary deviation enzyme (kallikrein) from distal tubule were observed at 80 mg/kg/day (converted to a 90-day equivalent: about 50 mg/kg/day) within a range of Category 2 (Result of the initial environmental risk assessment of chemicals, Vol. 10, Ministry of the Environment in Japan (2012)). Due to no organic change but effects on function found in the kidney for this substance and an organic change observed for sodium molybdate, an analog substance, this substance was classified in Category 2 (kidney).
10 Aspiration hazard Classification not possible
-
-
- - Due to lack of data, the classification is not possible.
