HEALTH HAZARDS

Hazard class		Classification	Pictogram Signal word	Hazard statement (code)	Precautionary statement (code)	Rationale for the classification	Classification year (FY)	GHS Classification Guidance for the Japanese Government
1	Acute toxicity (Oral)	Category 3	Danger	H301	P301+P310 P264 P270 P321 P330 P405 P501	Based on a LD50 value of 72 - 296 mg/kg for rats (CaPSAR (1994)), the substance was classified into Category 3.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）

FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
2	Skin corrosion/irritation	Category 2	Warning	H315	P302+P352 P332+P313 P362+P364 P264 P280 P321	Since there are a number of case reports of skin irritation following exposure to high levels of cadmium oxide fumes (CaPSAR (1994)), the substance was classified into Category 2.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
3	Serious eye damage/eye irritation	Category 2	Warning	H319	P305+P351+P338 P337+P313 P264 P280	Since there are a number of case reports of eye irritation following exposure to high levels of cadmium oxide fumes (CaPSAR (1994)), the substance was classified into Category 2.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
4	Respiratory sensitization	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
4	Skin sensitization	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
5	Germ cell mutagenicity	Category 2	Warning	H341	P308+P313 P201 P202 P280 P405 P501	[Rationale for the Classification] Because in vivo data on this substance itself available for the classification were not obtained, information on the whole cadmium compounds (as cadmium ion, Cd2+) was used for evaluation. From (1), (2), positive reports in germ cells and somatic cells were obtained on water-soluble cadmium chloride. Although water solubility of this substance is low, it may cause hazards similar to cadmium chloride when incorporated in the body, therefore, it was classified in Category 2. The category was revised by considering knowledge on the whole cadmium compounds and water solubility of this substance. [Evidence Data] (1) It is reported that after administration of cadmium (mainly cadmium chloride), chromosomal aberrations in mouse spermatocytes and hamster oocytes and altered gene expression in mouse spermatid occurred (ATSDR (2012), IARC 58 (1993)). (2) It is reported that as the result of administrating cadmium chloride to mice, dose-dependent increases in the incidences of micronuclei, sister chromatid exchanges, and chromosomal aberrations were observed in the peripheral blood. Moreover, it is reported that increased single strand breaks in the DNA were observed in rats after administrating cadmium chloride (EU-RAR (2007), DFGOT Vol. 22 (2006), NICNAS IMAP (Accessed Dec. 2018)). [Reference Data, etc.] (3) It is reported that increases in the incidences of micronuclei and sister chromatid exchanges in peripheral lymphocytes were shown in workers occupationally exposed to cadmium (compound not specified) and that human lymphocytes from people inhabiting cadmium-polluted areas of China were found to have increased micronuclei rates and a higher frequency of chromosomal aberrations and severe aberration types. However, conflicting knowledge is also reported (ATSDR (2012)). (4) As for in vivo, a dominant lethal test by administrating cadmium (mainly cadmium chloride) was negative (ATSDR (2012), IARC 58 (1993), DFGOT Vol. 22 (2006)). (5) As for in vitro, it is reported that a bacterial reverse mutation test, a chromosomal aberration test and a sister chromatid exchange test in cultured mammalian cells (CHO) were positive (NICNAS IMAP (Accessed Jan. 2019)). (6) Water solubility of this substance is 0.0096 g/L (DFGOT Vol. 22 (2006)). (7) This substance was classified in Muta. 2 in EU CLP.

6	Carcinogenicity	Category 1A	Danger	H350	P308+P313 P201 P202 P280 P405 P501	Since cadmium and cadmium compounds are classified into "Group 1" in IARC (IARC 58 (1993)), "K" in NTP (NTP Roc (11th, 2004)), and into Category 1 in Japan Society For Occupational Health (JSOH), the substance was classified into Category 1A.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
7	Reproductive toxicity	Category 2	Warning	H361	P308+P313 P201 P202 P280 P405 P501	In an inhalation developmental toxicity test in mice, a lower pregnancy rate, increased total number of resorptions per litter and an increase in the incidence of reduced sternebral ossification were observed at doses that were parental general toxic (NTP TOX39 (1995)). Based on the data, the substance was classified into Category 2. As relevant information, lower offspring body weight was observed at dose levels that were not parental general toxic.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
8	Specific target organ toxicity - Single exposure	Category 1 (respiratory organs, gastrointestinal system)	Danger	H370	P308+P311 P260 P264 P270 P321 P405 P501	For humans, a case of pneumonitis was reported for a man exposed to the substance for 3 days (ACGIH (7th, 2001)). Additionally, there is a report that 9 years after a single exposure to the substance, a worker continued to show signs of progressive pulmonary fibrosis and had no improvement in respiratory function (ATSDR (2008)). In dust inhalation tests with rats, exposures to 1 - 10 mg/m3 resulted in interstitial pneumonitis, alveolar epithelial hyperplasia, alveolitis with hemorrhage, and hyperplasia of fibroblasts (ATSDR (2008)). In addition, as acute effects of cadmium compounds to humans, "chemical pneumonitis and oedema after inhalation exposure, and rapid onset with severe nausea, vomiting, and abdominal pain after ingestion" are characteristic symptoms (EHC 134 (1992)). Based on the data, the substance was classified into Category 1 (respiratory system, alimentary system).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
9	Specific target organ toxicity - Repeated exposure	Category 1 (respiratory organs, kidney, bone, cardiovascular system)	Danger	H372	P260 P264 P270 P314 P501	There are reports of "in humans, long term inhalation of cadmium oxide fumes or dusts leads to reduced lung function and emphysema" and "a substantial body of information is available indicating that the lung, kidney and bone are the main target organs upon repeated exposure to cadmium oxide/cadmium metal in occupational settings (mainly by inhalation)" (SIDS (2004)). Additionally, it was reported that hypertension and abnormalities in the electrocardiogram were observed in workers at a battery factory exposed to cadmium oxide dust (EHC 134 (1992)). Based on the data, the substance was classified into Category 1 (respiratory system, kidney, bone, cardiovascular system). As relevant information, as chronic effects of cadmium compounds to humans, "renal dysfunction such as glomerular proteinuria, hypercalciuria, disturbances in rate of calcium to phosphate, hypophosphataemia, formation of renal stones, osteomalacia and osteoporosis" are characteristic (EHC 134 (1992)).
