4	Skin sensitization	Classification not possible	- -	-	-	Classification not possible due to lack of data. Although it is not the information on this substance, the manganese salt is reported to be negative in the LLNA test (Initial Risk Assessment Report (NITE, CERI, NEDO, 2008)), but details are unknown.	FY2017	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
5	Germ cell mutagenicity	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2017	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
6	Carcinogenicity	Classification not possible	- -	-	-	Although there is no data on this substance itself, EPA classified manganese in Category D (not classifiable as to human carcinogenicity) (IRIS (1995)). Therefore, based on this, this substance was classified as "Classification not possible."	FY2017	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
7	Reproductive toxicity	Category 1B	Danger	H360	P308+P313 P201 P202 P280 P405 P501	There is no data on this substance itself. However, for the classification of reproductive toxicity of manganese and manganese compounds, Japan Society For Occupational Health (JSOH) judged as follows: in humans, although impotence and decreased libido were often observed in manganese poisoning patients, these findings remain at the level of case reports, and are slightly weak as epidemiological evidence, and in addition, the data on decreased fertility in males was also limited (OEL Documentations (2014)). On the other hand, it is reported that fetal toxicity occurred in experimental animals. From the above findings, manganese and manganese compounds were classified as reproductive toxicants Group 2 by the Japan Society For Occupational Health (JSOH) (OEL Documentations (2014)). Therefore, this substance was classified in Category 1B based on the classification results by the Japan Society For Occupational Health.	FY2017	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
8	Specific target organ toxicity - Single exposure	Category 1 (respiratory organs)	Danger	H370	P308+P311 P260 P264 P270 P321 P405 P501	There is no information on single exposures of this substance in humans and experimental animals. There is the information that the substance is an inorganic manganese compound and is insoluble in water (GESTIS (Access on November 2017)). In the case of manganese dioxide (CAS RN 1313-13-9), another insoluble manganese compound, it is reported that a pulmonary inflammatory reaction occurs due to a single inhalation exposure of the dust in humans and its symptoms are cough, bronchitis, pneumonia, decreased pulmonary function (CICAD 12 (1999)). Based on this information, manganese dioxide was classified in Category 1 (respiratory) in the GHS classification in FY2014. In addition, manganese carbonate (CAS RN 598-62-9), an insoluble manganese compound, for which there is no information on single exposure, but based on the information on manganese dioxide, it was classified in Category 1 (Respiratory organs) in GHS classification in FY2016. It is considered that in the case of inhalation exposure, this substance may affect the respiratory organs like other insoluble manganese compounds. Therefore, it was classified in Category 1 (respiratory organs).	FY2017	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
9	Specific target organ toxicity - Repeated exposure	Category 1 (nervous system, respiratory organs)	Danger	H372	P260 P264 P270 P314 P501	Although it is not the information on this substance, when humans are exposed to excess amounts of manganese by the oral or inhalation route, memory disorders, psychiatric symptoms, etc. are observed as acute effects, and as chronic effects, symptoms of manganese addiction similar to those of Parkinson's disease are seen, such as gait disturbance and speech disorders. Serious effects were observed especially in inhalation exposure (Initial Risk Assessment Report (NITE, CERI, NEDO, 2008)). As for the oral route, in cases of drinking well water containing high concentrations of manganese, and in epidemiological studies on residents living in regions with high manganese concentrations, symptoms similar to manganese addiction such as mask-like faces, muscle rigidity, tremors and psychiatric disorders were reported (Initial Risk Assessment Report (NITE, CERI, NEDO, 2008)). The influence on the neurobehavioral function by exposure to the dust of manganese dioxide, trimanganese tetraoxide, and manganese salts (sulfate, carbonate, nitrate) in plants manufacturing manganese oxides and manganese salts was reported (Initial Risk Assessment Report (NITE, CERI, NEDO, 2008)). It is reported that neurotoxicity from manganese addiction occurred by occupational exposure to manganese dioxide, and that in addition to decreases in visual simple reaction time and in eye-hand coordination, rigidity of the hands was observed (SIDS (2012), Initial Risk Assessment Report (NITE, CERI, NEDO, 2008), ATSDR (2012)). Furthermore, many case reports revealed that manganese compounds, mainly manganese dioxide, produce respiratory disorders (cough, bronchitis, pneumonia, etc.) (ATSDR (2012)). No information is available for experimental animals. Therefore, this substance was classified in Category 1 (nervous system, respiratory organs).
