HEALTH HAZARDS

Hazard class		Classification	Pictogram Signal word	Hazard statement (code)	Precautionary statement (code)	Rationale for the classification
1	Acute toxicity (Oral)	Not classified	- -	-	-	It was classified as "Not classified" based on LD50 values for rats of 3,160 mg/kg (HSDB (2003)), > 20,000 mg/kg (males), and > 30,000 mg/kg (females) (Pesticide safety information (Japan Crop Protection Association), Japanese Journal of Pesticide Science Vol. 15, No. 3 (Pesticide Science Society of Japan, 1990)).
1	Acute toxicity (Dermal)	Not classified	- -	-	-	It was classified as "Not classified" based on an LD50 value of > 3,160 mg/kg for rabbits (HSDB (2005)) and an LD50 value of > 5,000 mg/kg for rats (Pesticide safety information (Japan Crop Protection Association), Japanese Journal of Pesticide Science Vol. 15, No. 3 (Pesticide Science Society of Japan, 1990)).
1	Acute toxicity (Inhalation: Gases)	Not applicable	- -	-	-	Solid (GHS definition)
1	Acute toxicity (Inhalation: Vapours)	Classification not possible	- -	-	-	No data available.
1	Acute toxicity (Inhalation: Dusts and mists)	Classification not possible	- -	-	-	Data are lacking. Besides, as List 3 data, it is reported that LCLo by 4-hour exposure was > 0.425 mg/L for rats (RTECS (2005): the original article, National Technical Information Service (Springfield, VA 22161): OTS0537028). However, because the category cannot be determined, the classification is not possible. Because the test concentration was above the saturated vapour pressure concentration (0.0019 mg/L), it was regarded as a test on dust.
2	Skin corrosion/irritation	Not classified	- -	-	-	It was classified as "Not classified" in the Classification JIS (corresponding to Category 3 in UN GHS classification) because, in a test in which 0.5 g of 50% wettable powder was applied to the rabbit skin for 24 hours, slight erythema and edema were observed by five days after the application, but these disappeared six days after the application, and it was judged as slightly irritating (Pesticide safety information (Japan Crop Protection Association), Japanese Journal of Pesticide Science Vol. 15, No. 3 (Pesticide Science Society of Japan, 1990)). Besides, there is also described that this substance is not a skin irritant in humans (HSDB (2005)).
3	Serious eye damage/eye irritation	Category 2B	- Warning	H320	P305+P351+P338 P337+P313 P264	It was classified in Category 2B because it is reported that slight irritation was observed in a test in which 3 mg was applied to the rabbit eye, but it disappeared by day 6 (HSDB (2005)), and in a test in which 100 mg of 50% wettable powder was applied to the rabbit eye, slight conjunctival irritation at 1 hour after the application and slight irritative changes also in the cornea and iris in addition to the conjunctiva after 24 hours were found, and about two weeks were needed for recovery, but it was judged as slightly irritating. Besides, it is also described that this substance is a slight eye irritant in humans (HSDB (2005)).
4	Respiratory sensitization	Classification not possible	- -	-	-	No data available.
4	Skin sensitization	Classification not possible	- -	-	-	It is reported that 50% wettable powder was not sensitizing in a skin sensitization test with guinea pigs (Pesticide safety information (Japan Crop Protection Association), Japanese Journal of Pesticide Science Vol. 15, No. 3 (Pesticide Science Society of Japan, 1990)), but it is List 2 data, and the details on the test method and test results (such as positive rate) are unknown. Therefore, it was classified as "Classification not possible."
5	Germ cell mutagenicity	Not classified	- -	-	-	It was classified as "Not classified" based on a negative result in a chromosomal aberration test with bone marrow cells after oral administration to mice (in vivo somatic cell mutagenicity test) (Pesticide safety information (Japan Crop Protection Association), Japanese Journal of Pesticide Science Vol. 15, No. 3 (Pesticide Science Society of Japan, 1990)). Besides, as for in vitro tests, in Ames tests, there are reports that it was positive in the TA100 strain (HSDB (2005)), false-positive only in the TA100 strain (not statistically significant but slight increase), and negative in the other strains (Pesticide safety information (Japan Crop Protection Association), Japanese Journal of Pesticide Science Vol. 15, No. 3 (Pesticide Science Society of Japan, 1990)).
6	Carcinogenicity	Classification not possible	- -	-	-	No data available.
7	Reproductive toxicity	Classification not possible	- -	-	-	In developmental toxicity tests by oral administration to pregnant rats and pregnant rabbits during the organogenesis period, maternal animals showed slightly reduced weight gain at the high doses (rats 50 mg/kg, rabbits 40 mg/kg) in both animal species, but no changes were observed in developmental parameters (such as the number of implantations, embryonic mortality, and the number of live fetuses), the incidence of malformations, and the growth of fetuses (Pesticide safety information (Japan Crop Protection Association), Japanese Journal of Pesticide Science Vol. 15, No. 3 (Pesticide Science Society of Japan, 1990)). No adverse effects on the development of were found offspring from the results, but it was impossible to judge the sexual function and fertility of parent animals because there are no data on exposure before mating. Therefore, it was classified as "Classification not possible" due to lack of data.
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	No data available.
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	It is reported that maximum no-effect level was judged to be 320 ppm (males: 38.3 mg/kg/day, females: 44.8 mg/kg/day) in a subacute toxicity test by 3-month diet administration to mice (0, 20, 80, 320, 1,280 ppm), at the highest dose of 1,280 ppm (males: 153.2 mg/kg/day, females: 179.2 mg/kg/day), four each of males and females died during the dosing period, and histopathological examination of dead animals revealed fatty degeneration in the liver, anisokaryosis in hepatocytes, Kupffer cell swelling, etc. and increased activities of ALP and GPT (males only) (Pesticide safety information (Japan Crop Protection Association), Japanese Journal of Pesticide Science Vol. 15, No. 3 (Pesticide Science Society of Japan, 1990)). From the results, effects on the liver were suggested, but the dose (1,280 ppm) was above the guidance value range, and the effects are unknown around the upper limit of the guidance values. Therefore, it was classified as "Classification not possible."
10	Aspiration hazard	Classification not possible	- -	-	-	No data available.

ENVIRONMENTAL HAZARDS

Hazard class		Classification	Pictogram Signal word	Hazard statement (code)	Precautionary statement (code)	Rationale for the classification
11	Hazardous to the aquatic environment (Acute)	Category 1	Warning	H400	P273 P391 P501	It was classified in Category 1 from 96-hour LC50 = 0.050 mg/L for fish (Oncorhynchus mykiss) (AQUIRE, 2012).
11	Hazardous to the aquatic environment (Long-term)	Category 1	Warning	H410	P273 P391 P501	Reliable chronic toxicity data were not obtained. It was classified in Category 1 because it is not rapidly degradable (BIOWIN), and it corresponds to Category 1 in acute toxicity for fish (AQUIRE, 2012).
12	Hazardous to the ozone layer	Classification not possible	- -	-	-	This substance is not listed in the Annexes to the Montreal Protocol.
