5	Germ cell mutagenicity	*	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.
6	Carcinogenicity	*	- -	-	-	[Rationale for the Classification] Based on the classification results by other organizations in (1), it was classified as "Classification not possible" in accordance with the GHS Classification Guidance for the Japanese Government. [Evidence Data] (1) As for classification results by domestic and international organizations, barium and soluble compounds were classified in A4 by ACGIH (ACGIH (7th, 2001)).
7	Reproductive toxicity	*	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.
8	Specific target organ toxicity - Single exposure	Category 1 (nervous system, cardiovascular system, muscular system, kidney, gastrointestinal tract), Category 3 (respiratory tract irritation)	Danger Warning	H370 H335	P308+P311 P260 P264 P270 P321 P405 P501 P304+P340 P403+P233 P261 P271 P312	[Rationale for the Classification] There are no reports on single exposure to this substance in humans or experimental animals. However, from (1), it is considered that information on other soluble barium compounds can be used as a reference since the substance is soluble in water. Therefore, based on (2) and (3), it was classified in Category 1 (nervous system, cardiovascular system, muscular system, kidney, gastrointestinal tract), Category 3 (respiratory tract irritation). [Evidence Data] (1) There is the information that this substance is very soluble in water (solubility: 1,041 g/L) (GESTIS (Access on August 2019)). (2) In humans, there are descriptions that accidental or intentional ingestion of high concentrations of soluble barium compounds causes gastrointestinal distress (vomiting, diarrhoea, abdominal pain, etc.) and hypokalemia, and as a result of hypokalemia, effects on the cardiovascular system (cardiac arrhythmias, increased or decreased blood pressure, etc.), the nervous system (skeletal muscle paralysis, etc.) and the kidneys (renal failure, etc.) occur (ATSDR (2007), ACGIH (7th, 2001), CICAD 33 (2001)). (3) Soluble barium compounds may cause local irritation of the eyes, nose, throat, bronchial tubes, and skin (HSDB (Access on October 2019)).
9	Specific target organ toxicity - Repeated exposure	Category 1 (cardiovascular system)	Danger	H372	P260 P264 P270 P314 P501	[Rationale for the Classification] Based on (1) and (2), since soluble barium compounds, including this substance, were estimated to cause effects on the cardiovascular system due to hypokalemia in humans, it was classified in Category 1 (cardiovascular system). [Evidence Data] (1) No significant alterations in blood pressure measurements or increases in the prevalence of hypertension, heart disease, or stroke were found among residents of two communities with different levels of soluble barium such as soluble barium chloride in drinking water. On the other hand, in another study, higher mortality rates for cardiovascular disease and heart disease (arteriosclerosis) were seen in a community with elevated soluble barium in drinking water (ATSDR (2007)). (2) Increased incidence of hypertension was reported among workers exposed to soluble barium at an average of 1.07 mg/m3 by mixing and grinding various grades of barium at a mineral processing facility (CICAD 33 (2001)). [Reference Data, etc.] (3) The barium ion is a chemical antagonist of potassium, and barium induces hypokalemia by promoting a transfer of potassium from extracellular to intracellular compartments (ACGIH (7th, 2001)). (4) In studies in which barium chloride (CAS RN 10361-37-2) or barium chloride dihydrate (CAS RN 10326-27-9) was administered in drinking water to rats or mice for 13 weeks or 2 years, effects on the kidney (death from nephropathy, tubule dilatation) were observed at doses exceeding Category 2 in all studies, and the kidney is described to be the most sensitive target organ in experimental animals (ATSDR (2007)). (5) Barium chloride was classified in Category 1 (cardiovascular system, nervous system, muscular system, kidney) (GHS Classification Result in FY2014).
10	Aspiration hazard	*	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.
