7 | Reproductive toxicity | Category 1B |
Danger |
H360 | P308+P313 P201 P202 P280 P405 P501 |
[Rationale for the Classification] Based on (1) and (2), it was classified in Category 1B. In (1), a reduction in gestation length in parental animals, a decrease in AGD, etc. in pups were observed at dose levels causing mild maternal toxicity. In consideration of the effects of the reduced gestation length and the delayed onset of puberty in pups, the RAC judged that the classification as Repr. 1B was appropriate. [Evidence Data] (1) It was reported that in a one-generation reproduction toxicity study with rats dosed by feeding (OECD TG 443, GLP), a decrease in body weight, reduced body weight gain, a reduction in food consumption, etc. in parental animals and reductioned AGD, deceases in seminal vesicle and prostate weight (males) in pups were observed at 800 ppm; and a reduction of gestation length in addition to the findings at 800 ppm in parental animals, and a decrease in preweaning pup body weight and a delay in preputial separation in addition to the findings at 800 ppm in pups were observed at 1,600 ppm (CLH Report (2018)). (2) It was reported that in a developmental toxicity study with rats dosed by gavage (GLP, days 6-15 of gestation), reduced body weight gain and a reduction in food consumption in parental animals and a slight increase in post-implantation fetal mortality in pups were observed at 160 mg/kg/day. It was reported that no teratogenicity was observed (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013), A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2009)). [Reference Data, etc.] (3) In the CLH Report, it was proposed that this substance should be classified as Repr. 1B because the reduction of gestation length in (1) was a significant effect on sexual function and fertility, and based on the developmental effects (reduced AGD, delayed onset of puberty, reduced pup weight, and decreases in seminal vesicle and prostate weight) that were not considered to be secondary to maternal toxicity, it should be also classified as Repr. 1B for developmental toxicity (CLH Report (2018)). (4) With respect to the proposition of (3), the RAC considered that the delayed onset of puberty (preputial separation, vaginal opening) should be included in the effects on sexual function and fertility, and the reduction of gestation length, delayed onset of puberty in pups, and marked effects on the reproductive organs in males were observed at dose levels causing mild or moderate maternal toxicity, therefore, the classification as Repr. 1B was appropriate. On the other hand, the RAC gave the opinion that the classification for developmental toxicity could not be justified because the reduced AGD was attributable to the lower birth weight due to the reduction of gestation length (RAC Opinion (2019). |

8 | Specific target organ toxicity - Single exposure | Not classified |
- |
- | - | [Rationale for the Classification] Based on (1) to (5), it was considered that this substance had no specific target organ toxicity at doses up to and within the range for Category 2 and it was classified as "Not classified." [Evidence Data] (1) It was reported that in an acute oral toxicity test with rats, piloerection, hunched posture, abnormal gait, lethargy, reduced respiratory rate, ptosis, paleness of limbs, and coma-like state were observed at 3,200 mg/kg to 5,000 mg/kg (in the range corresponding to "Not classified") (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013), A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2009)). (2) It was reported that in an acute oral toxicity test with mice, hypoactivity, prostration, piloerection, ataxia, and stained fur were observed at 1,500 mg/kg to 5,000 mg/kg (within the range for Category 2 and in the range corresponding to "Not classified) (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013), A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2009)). (3) It was reported that in an acute dermal toxicity test with rats, no deaths or symptoms were observed at 2,000 mg/kg (upper limit of Category 2) (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013), A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2009)). (4) It was reported that in an acute inhalation (dust) toxicity test with rats (4 hours), there was no death case, and completely closed eyelids, half-closed eyelids, abnormal respiratory pattern, abnormal posture, and stained fur were observed at 2.39 mg/L (within the range for Category 2) (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013), A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2009)). (5) It was reported that in an acute neurotoxicity test with rats by oral administration, a decrease in locomotor activity and impairment of gait and rearing were observed at or above 250 mg/kg (within the range for Category 1), but they were considered to be caused by the poor general condition after the oral administration, not by direct neurotoxicity (US Federal Register vol. 80, No. 168 (2015)). |

9 | Specific target organ toxicity - Repeated exposure | Category 2 (prostate) |
Warning |
H373 | P260 P314 P501 |
[Rationale for the Classification] Based on (1) and (2), it was classified in Category 2 (prostate). The findings on the liver (an increase in ALP, an increase in lipid droplets, an increase in the incidence of ground-glass foci of liver cells) in (1) to (3) were not considered to be target organ toxicity effects and were not adopted. [Evidence Data] (1) It was reported that in a 90-day oral toxicity test with dogs dosed by feeding (GLP), an increase in ALP and a decrease in prostate weight with fibrosis (males) were observed at 1,350 ppm (43.1 mg/kg/day (males), 43.7 mg/kg/day (females), within the range for Category 2) (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013). (2) It was reported that in a one-year chronic toxicity study with dogs dosed by feeding (GLP), an increase in ALP, an increase in liver weight, an increase in hepatic lipid droplets, and a decrease in prostate weight (males) were observed at 1,350 ppm (44.6 mg/kg/day (males), 47.0 mg/kg/day (females), within the range for Category 2) (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013)). (3) It was reported that in a two-year carcinogenicity study with rats dosed by feeding (GLP), reduced body weight gain, an increase in the incidence of ground-glass foci of liver cells, increases in the incidence of dilatation of mesenteric blood vessels and arteritis (in the pancreas in particular) and other effects (males) were observed at 2,000 ppm (94.6 mg/kg/day (males), 133 mg/kg/day (females), within the range for Category 2 to in the range corresponding to "Not classified") (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013)). [Reference Data, etc.] (4) It was reported that in a 90-day oral toxicity test with rats dosed by feeding (GLP), no significant toxicity findings were observed up to the highest dose of 1,000 ppm (73 mg/kg/day (males), 82 mg/kg/day (females), within the range for Category 2) (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013)). (5) It was reported that in a two-year chronic toxicity study with rats dosed by feeding (GLP), reduced body weight gain, mild anemia, increases in the incidence of dilatation of mesenteric blood vessels and arteritis (in the pancreas in particular) and other effects (males) were observed at 2,000 ppm (99.9 mg/kg/day (males), 158 mg/kg/day (females), within the range for Category 2 to in the range corresponding to "Not classified") (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013)). (6) It was reported that in a two-year carcinogenicity study with mice dosed by feeding (GLP), reduced body weight gain was observed at the highest dose of 1,000 mg/kg/day (in the range corresponding to "Not classified") (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013)). |
