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 4	Warning	H302	P301+P312 P264 P270 P330 P501	Its rat LD50 values documented are 825-1470 mg/kg (IUCLID (2000)), 800 mg/kg (IUCLID (2000)), and 344 mg/kg (HSDB (2008)). All values fall under Category 4. As additional background information, since only the (+) form has physiological activities as herbicides, data on a (+)/(-) racemic mixture are scarce. Thus, when data on a racemic mixture were not available, evaluations were carried out using the (+) form data.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Dermal)	Not classified	- -	-	-	Its rat LD50 of > 4000 mg/kg falls under the "Not classified" category.	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	- -	-	-	Its rat LC50 is reported to be > 0.65 mg/L/4h (HSDB (2008)). Classification is not possible based only on this value. Given that its saturated vapour pressure is 0.2 mg/L, the study was presumably conducted in a dust state.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
2	Skin corrosion/irritation	Category 2	Warning	H315	P302+P352 P332+P313 P362+P364 P264 P280 P321	A Draize test using rabbits found the substance irritating (IUCLID (2000)), and another Draize test using rabbits that received a racemic mixture found the substance to be a mild to moderate irritant (HSDB (2008)). In addition to these results, since the substance is rated as R38 in the EU classification, it was classified into Category 2.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
3	Serious eye damage/eye irritation	Category 1	Danger	H318	P305+P351+P338 P280 P310	A Draize test using rabbits found the substance irritating (IUCLID (2000)), and a rabbit test using a racemic mixture found the substance to be a severe to corrosive irritant (HSDB (2008)). In addition to these results, since the substance is rated as R41 in the EU classification, it was classified into Category 1.	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	- -	-	-	Both a guinea pig maximization test and a test using a racemic mixture found the substance not a sensitizer (IUCLID (2000), HSDB (2008)). These negative results indicate that the substance falls under the "Not classified" category. However, since these are List 2 studies, it was classified into the "Classification not possible" category.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
5	Germ cell mutagenicity	Not classified	- -	-	-	In sister chromatid exchange assays using Chinese hamsters that received oral administration of a racemic mixture (in vivo genotoxicity tests), positive results were found at toxic doses only, and its genotoxic effect at sub-toxic dose levels could not be determined (HSDB (2008)). Regarding in vitro tests, Ames tests, chromosomal aberration tests using CHL cells, and mutation tests using V79 cells all yielded negative results (HSDB (2008)). No in vivo test results using a macemic mixture are available. However, since chromosomal aberration tests using bone marrow cells of Chinese hamsters that underwent oral administration of the (+) form (in vivo mutagenicity tests using somatic cells) yielded negative results (HSDB (2008)), the substance was classified into the "Not classified" category.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
6	Carcinogenicity	Category 2	Warning	H351	P308+P313 P201 P202 P280 P405 P501	Since the substance is rated as Group 2B by the IARC (IARC (1987)), it was classified into Category 2. As additional background information, no increase in incidences of tumorigenesis was noted in either 2-year mixed diet tests using rats, or 18-month mixed diet tests using mice (IUCLID (2000)).	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
7	Reproductive toxicity	Category 1B	Danger	H360	P308+P313 P201 P202 P280 P405 P501	In two-generation reproduction tests using rats (OECD TG 416), no abnormalities were noted in sexual functions and fertility of parental animals or in the offspring (IUCLID (2000)). In oral administration tests conducted during the organogenetic period using rats or rabbits, abnormalities were detected in organs and skeletons of the offspring at non-toxic doses to parental animals (IUCLID (2000)). In addition, in developmental toxicity tests using mice, cleft palate was observed (Birth Defects (3rd, 2000)). Though data on a racemic mixture are not available, using the (+) form data, the substance was classified into Category 1B.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
8	Specific target organ toxicity - Single exposure	Category 2 (nervous system)	Warning	H371	P308+P311 P260 P264 P270 P405 P501	Although it is unconfirmed if this study was conducted using a racemic mixture, rats that received oral administration of 250 mg/kg bw or higher doses showed nervous effects (e.g., hypothermia, decreased number of rearing, increased limb splay, retarded righting response, and decreased grip strength) (HSDB (2008)), indicating that the substance falls under Category 1. However, since this is a List 2 study, the substance was classified into Category 2 (nervous system).	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	Though this study is not conducted using a racemic mixture, rats that received oral administration for 90 days (doses: 7.2, 36.7, and 193 mg/kg for male; 8.3, 41.4, and 208 mg/kg for female) showed changes in liver weights, biochemical parameters, and hematological parameters at the doses of 193 and 208 mg/kg, which are above Category 2 guidance values; and no effects were seen other than changes in kidney weights at 36.7 and 41.7 mg/kg, which fall under Category 2 guidance doses (HSDB (2008)). In 13-week oral administration tests using rats (doses: 20, 224, and 683 mg/kg for male; 33, 380, and 1043 mg/kg for female), no effects were noted other than changes in eosinophilia in renal tubule cells, liver weights, biochemical parameters, and hematological parameters at the doses of 683 mg/kg and 1043 mg/kg, which are beyond Category guidance doses (HSDB (2008)). In addition, 13-week rat tests found similar changes in the liver and kidney. However, in any of the above studies, toxic effects of the test substance at doses that fall under the range of guidance values are not clear. Thus, the substance was classified into the "Classification not possible" category.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
10	Aspiration hazard	Classification not possible	- -	-	-	No data available.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）

11	Hazardous to the aquatic environment Short term (Acute)	Category 1	Warning	H400	P273 P391 P501	Since its 96-hour LC50 = 0.5 mg/L for fish (rainbow trout) (HSDB, 1998), the substance was classified into Category 1.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
11	Hazardous to the aquatic environment Long term (Chronic)	Category 1	Warning	H410	P273 P391 P501	Since its classification for acute toxicity is Category 1, and it is not rapidly degradable (SRC: BioWin V4.10), the substance was classified into Category 1.
