Carcinogenicity

There is no carcinogenicity information on this substance or on the fluorides.
However, as described in the same hazard class on the GHS classification ofbarium (CAS RN 7440-39-3), the EPA classified barium and its compounds asGroup D or NL (IRIS (1998)) and ACGIH classified barium and its solublecompounds 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 otherorganizations.

Reproductive toxicity

Classification not possible due to lack of data. Besides, there is a description(EHC 107 (1990)) that in a test in which the substance was orally administered topregnant rats on the first days of gestation, decreases in the survival of 5-dayold embryos and in newborn birth weights, and increase in mortality rate ofnewborn were observed, however, no incidence of malformation was observed.

Specific target organ toxicity(singleIn ACGIH (7th, 2001), there is a description that fluorides cause irritation toexposure)
the respiratory tract. Therefore, this substance was classified in Category 3(respiratory tract irritation).
Specific target organtoxicity(repeated exposure)

There is no information on this substance itself.
However, it is said that the toxicity of barium and barium compounds depends
largely on the solubility, and that the toxicity is an inhibitory action of potassiumchannel by barium ions (ATSDR (2007)). The barium ions and the solublecompounds of barium (notably barium chloride, barium nitrate, barium hydroxide)
are toxic to humans. Although barium carbonate is relatively insoluble in water, it
is toxic to humans because it is soluble in the gastrointestinal tract. The
insoluble compounds of barium (notably barium sulfate) are inefficient sources ofthe barium ion and are therefore generally nontoxic to humans (ATSDR (2007)).
Therefore, this substance is thought to exhibit similar target organs as thoseexhibited by soluble barium.
It is reported that incidences of hypertension, heart disease, and strokeincreased 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 wasobserved in other similar groups (ATSDR (2007)). For the inhalation route, a highrate of elevated blood pressure was reported among workers exposed to solublebarium (mean 1.07 g/㎥) through work that involved blending and grinding several
grades of barium at a mineral processing facility (CICAD 33 (2001)). It is writtenthat among the effects of soluble barium in humans, ingestion of high levels ofsoluble barium compounds may cause the following acute effects: gastroenteritis(vomiting, diarrhoea, abdominal pain), hypopotassemia, hypertension, cardiac
arrhythmias, and skeletal muscle paralysis (CICAD 33 (2001)).
Additionally, 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 (convertedguidance value as barium dichloride: 271-803 mg/kg/day). It is described that thekidneys are the most sensitive target organ in the experimental animals (ATSDR(2007)). Therefore, the kidneys are thought to be one of the target organs inhumans as well.
Additionally, in the "Fluorides" of ACGIH, it is reported that bone lesions
related to fluorosis caused by occupational exposure to inorganic fluorides(ACGIH (7th, 2001)).
From the above, effects of soluble barium compounds including this substancewere thought to have a high probability of occurring in the cardiovascular system,
nervous system, muscular system, and kidneys. In addition, as a fluoride, thissubstance may have effects on the bones. Therefore, the substance wasclassified in Category 1 (cardiovascular system, nervous system, muscularsystem, kidney, bone).
