| 1 | Acute toxicity (Oral) | Category 4 |
 Warning |
H302 |
P301+P312
P264 P270 P330 P501 |
There are four reported LD50 values for rats of 1,030 mg/kg (males), 1,130 mg/kg (females) (EPA RED (1997), A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2009), Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2010)), 1,236 mg/kg (males) and 1,289 mg/kg (females) (A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2009)) (1,240 mg/kg (males) and 1,290 mg/kg (females) were listed for the same data in Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2010)). Based on these data, this substance was classified in Category 4. |
| 1 | Acute toxicity (Dermal) | Not classified |
- |
- | - |
There are the reported LD50 values for rats of > 2,000 mg/kg and > 5,000 mg/kg (A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2009), Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2010). One value is equivalent to "Not classified" (Category 5 in UN GHS classification) - "Not classified," and the other value is equivalent to "Not classified." There is a report that the LD50 value for rabbits is > 2,000 mg/kg (EPA RED (1997)), and it corresponds to "Not classified" (Category 5 in UN GHS classification) - "Not classified." Based on these data, this substance was classified as "Not classified." |
| 1 | Acute toxicity (Inhalation: Gases) | Not applicable |
- |
- | - | Liquid (GHS definition) |
| 1 | Acute toxicity (Inhalation: Vapours) | Classification not possible |
- |
- | - | Classification not possible due to lack of data. |
| 1 | Acute toxicity (Inhalation: Dusts and mists) | Classification not possible |
- |
- | - |
Classification not possible due to lack of data. Besides, it is reported that the LC50 (4 hours) value for rats is > 2.43 mg/L (A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2009), Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2010), and this corresponds to Category 4 or "Not classified." However, classification is not possible because a category cannot be specified only with this value. Note that the reference value as mist was applied since this LC50 value is higher than the saturated vapor pressure concentration (0.00031 mg/L). |
| 2 | Skin corrosion/irritation | Not classified |
- |
- | - | In a skin irritation test (details unknown) using rabbits, slight irritation has been reported (EPA RED (1997)). Moreover, in a skin irritation test (GLP test) using rabbits, the mean scores of all the animals (3 animals) at 24, 48 and 72 hours after application for 4 hours were 0.3, 0.3, 0 for erythema and crust, and 0, 0, 0 for edema, respectively. Irritation was not observed (A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2009)). From these results, it was thought that irritation of this substance was within the range of no irritation to very slight irritation. Therefore, this substance was classified as "Not classified." |
| 3 | Serious eye damage/eye irritation | Not classified |
- |
- | - |
It is reported that in an eye irritation test (GLP test) using rabbits, the average scores for corneal opacity, iritis, corneal redness, cornea edema of all the animals (3 animals) at 24, 48 and 72 hours after application were 0 for all, and that no irritation was observed (A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2009)). It is described that in another eye irritation test using rabbits, slight irritation was observed. However, the details are unknown (EPA RED (1997)). Therefore, this substance was classified as "Not classified." |
| 4 | Respiratory sensitization | Classification not possible |
- |
- | - | Classification not possible due to lack of data. |
| 4 | Skin sensitization | Not classified |
- |
- | - |
In a skin sensitization test (Buehler method, GLP test) using guinea pigs, sensitization was negative (sensitization rate: 0) (A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2009)). Although the details are unknown, in another skin sensitization test using guinea pigs, it was also negative, and it is concluded that this substance is not a sensitizer (EPA RED (1997)). Therefore, this substance was classified as "Not classified." |
| 5 | Germ cell mutagenicity | Category 2 |
 Warning |
H341 |
P308+P313
P201 P202 P280 P405 P501 |
As for in vivo data, a mouse dominant lethal test is negative, a micronucleus test using mouse bone marrow cells is positive and an unscheduled DNA synthesis test using rat hepatocytes is negative (EPA RED (1997), Evaluation of effects for food safety (Food Safety Commission, 2010), A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2009)). As for in vitro data, a bacterial reverse mutation test is negative, a mouse lymphoma test using cultured mammalian cells is positive, and chromosomal aberration tests have shown positive and negative results (EPA RED (1997), Evaluation of effects for food safety (Food Safety Commission, 2010), A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2009)). From the above, this substance was classified in Category 2 according to the GHS classification guidance for the Japanese Government. |
| 6 | Carcinogenicity | Classification not possible |
- |
- | - | In 2-year carcinogenicity studies using rats and mice given this substance by feeding, no evidence of carcinogenicity has been observed (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2010), EPA RED (1997)). The EPA classified the carcinogenicity of this substance in Group D. Therefore, this substance was classified as "Classification not possible" for this hazard class based on the classification result by the EPA. |
| 7 | Reproductive toxicity | Category 2 |
Warning |
H361 |
P308+P313
P201 P202 P280 P405 P501 |
As for two 2-generation studies using rats given this substance by the oral route (feeding), in one study of them at doses (20 and 100 mg/kg/day) where the effects on systemic toxicity (decreased weight gain, increase in liver and kidney weights, centrilobular hepatocyte hypertrophy, regeneration and degeneration of renal tubular epithelium, etc.) in F0 and F1 parental animals were manifested, there were no adverse effects on fertility of the parent animals and occurrence and development of F1 and F2 pups (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2010), EPA RED (1997)). However, in the other study, at the dose (40 mg/kg/day) where decreased weight gain was observed in F0 and F1 parental animals, a decrease in survival rate was observed in F1 and F2 pups (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2010)). In developmental toxicity studies using pregnant rats and pregnant rabbits dosed by the oral route (gavage, Days 6-18 of gestation), in rats, only slight effects (lower body weight, sternal variation) were observed at 150 mg/kg/day where decreased weight gain was observed in the dams, and in rabbits, there was no effect on the fetuses at up to 200 mg/kg/day where an increase in liver weights was observed in the dams (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2010), EPA RED (1997)). From the above, in one of the two 2-generation studies using rats, a decrease in the survival rate of pups was observed at the dose where decreased weight gain occurred in the parental animals. Therefore, this substance was classified in Category 2 for this hazard class. |
| 8 | Specific target organ toxicity - Single exposure | Category 2 (nervous system) |
Warning |
H371 |
P308+P311
P260 P264 P270 P405 P501 |
It is reported that in a single oral dose study using rats, gait abnormalities, decreased mobility, decreased sensory responses, decreased hindlimb resistance and decreased average body temperature were observed at 500 mg/kg, which corresponds to Category 2, or above (EPA RED (1997)); and that calm, gait abnormality, lacrimation, prone position, hypotonia, coarse breathing, and ptosis were observed at 833 mg/kg and above (A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2009)). Therefore, this substance was classified in Category 2 (nervous system). Besides the above, regarding the cholinesterase inhibitory action of this substance, there is no in vivo data, and as for in vitro, there is a description that the IC50 value for inhibition of bovine erythrocyte cholinesterase activity was > 1 mM (A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2009)). |
| 9 | Specific target organ toxicity - Repeated exposure | Category 2 (liver, kidney) |
Warning |
H373 |
P260
P314 P501 |
There is no information on humans. In a 90-day repeated dose toxicity study using rats given this substance by feeding, increases in alkaline phosphatase, urea nitrogen and creatinine; increased relative liver weights; centrilobular hepatocyte hypertrophy; basophilic change and hyaline droplet deposit of cortex renal tubule and casts in medullary renal tubule in the kidneys, etc. have been reported at 750 ppm (male: 44.2 mg/kg/day, female: 51.8 mg/kg/day), which is equivalent to Category 2, or above (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2010)). Moreover, in a 2-year carcinogenicity study using mice, an increase in diffuse pale hepatocyte and fine and large fat-containing vacuoles of the intermediate zone lobule in the liver, etc. have been observed at 100 ppm (male: 10 mg/kg/day, female: 11 mg/kg/day), which is within the range of Category 2, or above (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2010)). Besides, changes in the kidneys in rats were observed only in males, but for hyaline droplet deposit of cortex renal tubule, as a result of immunostaining of alpha 2-microglobulin was performed, no evidence that the hyaline droplet deposition was alpha 2-microglobulin was obtained (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2010). Therefore, since the finding was not alpha 2-microglobulin nephropathy peculiar to male rats, the liver was regarded as the target organ. From the above, this substance was classified in Category 2 (liver, kidney). |
