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	Since its rat oral LD50 is 80 mg/kg (HSDB, 2003), the substance was classified into Category 3.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Dermal)	Classification not possible	- -	-	-	Based on rat dermal LD50 values of > 500 mg/kg (Initial Risk Assessment Report (NITE, CERI, NEDO) (2008)) and > 2400 mg/kg (RETCS, 2004, original literature: Toxicology and Applied Pharmacology 14, 515 (1969)), classification of the substance is not possible because a category under which this substance falls cannot be determined.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	Solid (GHS definition)	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Inhalation: Vapours)	Classification not possible	- -	-	-	No data available.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Inhalation: Dusts and mists)	Classification not possible	- -	-	-	No data available.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
2	Skin corrosion/irritation	Classification not possible	- -	-	-	Inorganic arsenic compounds are reported to cause irritation (DFGOT vol. 21, 2005). However, since no further information is available, classification is not possible.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
3	Serious eye damage/eye irritation	Category 2	Warning	H319	P305+P351+P338 P337+P313 P264 P280	Since inorganic arsenic compounds are reported to irritate human eyes (HSG 70, 1992; PIM 042, 1996), this substance was classified into Category 2.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
4	Respiratory sensitization	Classification not possible	- -	-	-	No data available.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
4	Skin sensitization	Classification not possible	- -	-	-	No test results are available on this substance or any other inorganic lead compounds. Although inorganic arsenic compounds may cause skin sensitization in humans, this is not a definitive conclusion (ATSDR, 2005; HSG, 1992). According to EHC 224 (2001), dermal sensitization to inorganic arsenic appears to be a rare occurrence in humans. Overall, due to insufficient study results available, the substance was classified into the "classification not possible" category.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
5	Germ cell mutagenicity	Classification not possible	- -	-	-	No data available. The DFG in Germany has classified arsenic and its inorganic compounds, including lead arsenate (Pb3(AsO4)2, CAS 3687-31-8), into Category 3A for germ cell mutagenicity (which is equivalent to Category 1B to 2 in the GHS classification) (MAK/BAT, 2007).	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
6	Carcinogenicity	Category 1A	Danger	H350	P308+P313 P201 P202 P280 P405 P501	According to IARC Suppl. 7 (1987), ACGIH-TLV (2008), and MAK/BAT (2007), arsenic and its inorganic compounds are categorized as human carcinogens. Thus, the substance was classified into Category 1A.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
7	Reproductive toxicity	Category 2	Warning	H361	P308+P313 P201 P202 P280 P405 P501	No test results on this substance were found, but according to description for arsenic and arsenic compounds documented in EHC 224 (2001) which is a List 1 information source, these substances are suggested to affect human reproduction and have teratogenic effects at doses that are toxic to maternal animals. Thus, the substance was classified into Category 2. As additional background information, the Catalog of teratogenic agents (2004), which is equivalent to List 1 sources, supports the conclusion that inorganic arsenic is not teratogenic to humans.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
8	Specific target organ toxicity - Single exposure	Category 1 (gastrointestinal system, circulatory system, nervous system, blood system, respiratory organs, skin, kidney, liver)	Danger	H370	P308+P311 P260 P264 P270 P321 P405 P501	Lead arsenate (CAS 3687-31-8) causes acute toxic symptoms such as gastroenteritis, diarrhea, convulsions, and paralysis (ACGIH, 2001). In addition, in humans, the following acute toxic effects by arsenic compounds are documented: symptoms of the gastrointestinal tract, cardiovascular system, nerves, and blood system; conjunctivitis and dermatitis as well as irritation to the nasal mucosa, pharynx, and trachea; frequent urination or anuria due to a blockage of renal tubules with clots of hemoglobin (IARC 23 (1980)); depression of bone marrow functions; and hepatomegaly (EHC 224 (2001)). In accordance with these reports, the digestive system, circulatory system, nervous system, blood system, respiratory system, skin, kidney, and liver were considered to be target organs of these compounds, and this substance was classified into Category 1 (digestive system, circulatory system, nervous system, blood system, respiratory system, skin, kidney, and liver).	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
9	Specific target organ toxicity - Repeated exposure	Category 1 (gastrointestinal system, circulatory system, nervous system, kidney, liver, blood system, respiratory system, skin)	Danger	H372	P260 P264 P270 P314 P501	Lead arsenate (Pb3(AsO4)2 (CAS 3687-31-8) affects the central nervous system and causes anemia and nephropathy (ACGIH-TLV, 2001). In addition, according to EHC 224 (2001) on arsenic and its inorganic compounds in relation to humans, gastrointestinal tract disorder; nervous disorder; effects on the blood system; and abnormalities in cardiovascular system, kidney, and liver were observed. Thus, target organs for these substances are the gastrointestinal tract, heart, brain, and kidney. In addition, the skin, bone marrow and peripheral nervous system are also affected by these substances. Moreover, according to ACGIH (2001), the upper respiratory tract and lung are also affected. Based on these reports, this substance was classified into Category 1 (digestive system, circulatory system, nervous system, kidney, liver, blood system, respiratory system, and skin).
