| 6 | Carcinogenicity | Classification not possible |
- |
- | - | There is no carcinogenicity information on this substance itself. However, as described in the same hazard class on the GHS classification of barium (CAS RN 7440-39-3), the EPA classified barium and its compounds as Group D or NL (IRIS (1998)) and ACGIH classified barium and its soluble compounds as A4 (ACGIH (7th, 2001)) based on results from animal tests using barium chloride dihydrate. Therefore, this substance was also classified as "Classification not possible" based on these classifications by other organizations. |

This substance reacts with water to form barium hydroxide. In humans, as adverse effects of soluble barium compounds by oral intake or inhalation, gastrointestinal symptoms (nausea, vomiting, colic, and diarrhea), myocardial and general muscular stimulation, and hypokalemia have been reported along with reports on severe cases including general muscular paralysis, and death from respiratory arrest or ventricular fibrillation (ACGIH (7th, 2001)). Additionally, it is written that accidental or intentional ingestion of soluble barium compounds at high concentrations causes gastroenteritis (vomiting, diarrhoea, abdominal pain), hypokalemia, hypertension, cardiac arrhythmias, skeletal muscle paralysis, and renal failure (CICAD 33 (2001), ATSDR (2007)). It is reported that barium oxide and barium hydroxide irritate the respiratory tract (CICAD 33 (2001)). From the above, this substance was classified in Category 1 (the nervous system, cardiovascular system, muscular system, kidney, gastrointestinal tract), and Category 3 (respiratory tract irritation) because the substance was thought to have similar effects as barium hydroxide. |

There is no information on this substance itself. It is said that the toxicity of barium and barium compounds depends largely on the solubility, and toxicity is an inhibitory action of potassium channel by barium ion (ATSDR (2007)). The water solubility of this substance is 0.091g/100 g (HSDB (Access on May 2016)), thus it is difficult to dissolve in water, but decomposes on contact with water or acids (ICSC (J) (1999), HSDB (Access on May 2016)). Therefore, this substance is thought to have similar target organs as the soluble barium compounds have. It is reported that incidences of hypertension, heart disease, and stroke increased in a population of neighborhood who ingested drinking water containing water soluble barium such as barium chloride, and that an increase in mortality due to heart diseases such as vascular disorder and arteriosclerosis was observed in other similar groups (ATSDR (2007)). For the inhalation route, a high rate of elevated blood pressure was reported among workers exposed to soluble barium (mean 1.07 g/m3) through work that involved blending and grinding several grades of barium at a mineral processing facility (CICAD 33 (2001)). Among the effects of soluble barium in humans, ingestion of high levels of soluble barium compounds may cause the following acute effects: gastroenteritis (vomiting, diarrhoea, abdominal pain), hypopotassemia, hypertension, cardiac arrhythmias, and skeletal muscle paralysis (CICAD 33 (2001)). There are only several reported cases that renal failure and renal insufficiency occurred as acute barium poisoning. However, as for experimental animals, in 13-week or 2-year studies of barium dichloride or its dihydrate administered to rats or mice in drinking water, deaths attributed to nephropathy were observed at doses corresponding to Category 2 or higher (converted guidance value as barium dichloride: 271-803 mg/kg/day). It is described that the kidneys are the most sensitive target organ in the experimental animals (ATSDR (2007)). Therefore, the kidneys are thought to be one of the target organs in humans as well. From the above, effects from soluble barium compounds including this substance were thought to have a high probability of occurring in the cardiovascular system, nervous system, muscular system, and kidneys. Therefore, this substance was classified in Category 1 (cardiovascular system, nervous system, muscular system, kidney). In addition, there was a description in HSDB (Access on May 2016) that heavy exposure to the dust may produce benign pneumoconiosis. |
