1	Acute toxicity (Inhalation: Dusts and mists)	Classification not possible	- -	-	-	[Rationale for the Classification] Based on (1), because it was impossible to identify the category, it was classified as "Classification not possible." Besides, since the LC50 values were higher than the saturated vapor concentration (0.000002 mg/L), the reference value in units of mg/L was applied as the dust. [Evidence Data] (1) LC50 for rats (4 hours): >1,300 mg/m3 (1.3 mg/L) (PATTY (6th, 2012), ACGIH (7th, 2019), HSDB (Access on July 2019)).

[Evidence Data] (1) This substance was slightly irritating to the eyes but not irritating and sensitizing to the skin (EPA Pesticide (2000), HSDB (Access on July 2019)). (2) In a skin sensitization test (Buehler method) with guinea pigs, this substance was not sensitizing to the skin (JMPR (2006)). (3) This substance was slightly irritating to the skin and eyes, however, it was not a skin sensitizer (PATTY (6th, 2012)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
5	Germ cell mutagenicity	Classification not possible	- -	-	-	[Rationale for the Classification] There was no in vivo data, therefore, classification was not possible due to lack of data. [Evidence Data] (1) As for in vitro, negative results were reported in a bacterial reverse mutation test, and a chromosome aberration test and an unscheduled DNA synthesis test with cultured mammalian cells (PATTY (6th, 2012)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
6	Carcinogenicity	Classification not possible	- -	-	-	[Rationale for the Classification] Based on the classification results by other organizations in (1), it was classified as "Classification not possible" in accordance with the GHS Classification Guidance for the Japanese Government. [Evidence Data] (1) As the classification results by domestic and international organizations, it was classified as A4 by ACGIH (ACGIH (7th, 2019)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
7	Reproductive toxicity	Not classified	- -	-	-	[Rationale for the Classification] Based on (1) and (2), it was classified as "Not classified."

(2) In a developmental toxicity test with rabbits by oral or dermal administration, reduced body weight gain was seen in maternal animals by dermal application. No developmental toxicity was observed, however, in either administration route (ACGIH (7th, 2019), PATTY (6th, 2012)). [Reference Data, etc.] (3) In an oral administration test at one dose throughout mating, gestation, parturition and lactation, no effects on the number of litters, litter size, viability of young, or incidence of malformations were observed. However, inhibition of RBC cholinesterase activity in dams and 21-day-old pups (90% decrease in dams and 30% decrease in pups) was observed (ACGIH (7th, 2019), PATTY (6th, 2012))	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
8	Specific target organ toxicity - Single exposure	Category 2 (nervous system)	Warning	H371	P308+P311 P260 P264 P270 P405 P501	[Rationale for the Classification] There was no information on single exposure in humans. Based on (1)-(3), it was classified in Category 2 (nervous system). [Evidence Data] (1) This substance is an organophosphorus pesticide and affects the nervous system due to inhibition of cholinesterase (ACGIH (7th, 2019), IPCS, PIM G001 (1986)). (2) In oral exposure tests with rats and mice, this substance caused typical signs of organophosphate poisoning with single doses as low as 500 mg/kg (corresponding to Category 2) (ACGIH (7th, 2019), PATTY (6th, 2012)). (3) Signs of toxicity observed in animals treated with high doses of this substance are typical of acute toxicity signs induced by cholinesterase inhibition such as hypoactivity, labored breathing, rough coat, chromodacryorrhea, salivation, muscle spasms and tremors (EPA Pesticide (2000)). [Reference Data, etc.] (4) This substance might cause cholinesterase inhibition in humans, affecting the nervous system to result in nausea, dizziness and confusion. A large amount of exposure (accidents or leakages) may cause respiratory distress and result in death (HSDB (Access on July 2019)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
9	Specific target organ toxicity - Repeated exposure	Category 1 (nervous system)	Danger	H372	P260 P264 P270 P314 P501	[Rationale for the Classification] Based on (1)-(3), in oral dose tests with experimental animals, cholinesterase activity inhibition was observed in erythrocytes at doses within the range for Category 1 and in the brain at doses within the range for Category 2. Therefore, it was classified in Category 1 (nervous system). [Evidence Data] (1) In a 90-day feeding test with rats at 2-350 ppm, inhibition of erythrocyte cholinesterase activity was observed at or above 18 ppm (0.9 mg/kg/day, within the range for Category 1) (ACGIH (7th, 2019)). (2) In a 129-day feeding test with dogs at 10, 50 ppm, inhibition of erythrocyte cholinesterase activity was observed at 50 ppm (3-4 mg/kg/day, within the range for Category 1) (ACGIH (7th, 2019), JMPR (2006)). (3) In a 2-year feeding test with dogs, cholinergic symptoms, inhibition of erythrocyte cholinesterase activity and inhibition of brain cholinesterase activity were observed at 12.5 mg/kg/day (within the range for Category 2) (JMPR (2006)). [Reference Data, etc.] (4) In humans, repeated oral doses of up to 3.7 mg/kg were without cholinergic effects (ACGIH (7th, 2019)). (5) In humans exposed to this substance at 1.1 mg/kg/day for 4 weeks, or at 4.27 mg/kg/day for 5 days, there was no inhibition of cholinesterase activity in erythrocytes or plasma (JMPR (2006)).
