5 | Germ cell mutagenicity | Classification not possible |
- |
- | - | No data available. As data of sodium fluoride (CAS 7681-49-4), there are reports of positive results in a mouse bone marrow in vivo micronucleus test and a chromosomal aberration test when administered by intraperitoneal injection, but negative results was reported when administered orally (ATSDR (2003)). In the human hazard assessment, "Not classified" is considered to be appropriate. | FY2009 | GHS Classification Guidance by the Japanese Government (March, 2009) |
6 | Carcinogenicity | Not classified |
- |
- | - | Inorganic fluorides are classified into "Group 3" in IARC (IARC suppl. 7 (1987)). | FY2009 | GHS Classification Guidance by the Japanese Government (March, 2009) |

Danger |
H370 | P308+P311 P260 P264 P270 P321 P405 P501 |
Although no data for the substance is available, the substance was classified into Category 1 (respiratory system) based on a report that death is usually caused by respiratory paralysis in human cases of fluoride poisoning (IARC vol. 27 (1982)). As relevant information, there is a report that lethal doses of inorganic fluoride compounds were 50 - 225 mg/kg, and acute congestion of the abdominal organs, edema of the liver, kidney and renal tube, hemorrhage of the lung and dilatation of the right ventricle were observed at necropsy (IARC vol. 27 (1982)). | FY2009 | GHS Classification Guidance by the Japanese Government (March, 2009) |
9 | Specific target organ toxicity - Repeated exposure | Category 1 (teeth, bone, kidney) |
Danger |
H372 | P260 P264 P270 P314 P501 |
No data for the substance is available. However, in human cases, chronic exposure of fluoride compounds can impair the teeth, bone and kidney, and continuous ingestion of inorganic fluoride compounds can promote osteosclerosis by accumulation of fluorides in the bone. In areas with drinking water containing 5 - 16.2 ppm fluoride, low urea clearance and glomerular filtration rate, high blood urea level, as well as increases in incidence of skeletal deformity and renal calculus were reported. Additionally, dental fluorosis can occur when daily mean fluoride concentration in the drinking water and food is 2 ppm and above (IARC vol. 27 (1982)). Based on these information, the substance was classified into Category (tooth, bone, kidney). | FY2009 | GHS Classification Guidance by the Japanese Government (March, 2009) |
