In either test, no tumor formation was found in females (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013)). (3) In a carcinogenicity test by 18-month diet administration of this substance to male and female mice, no treatment-related increase in neoplastic lesions was seen (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013)). |
| 7 | Reproductive toxicity | Category 1B |
Danger |
H360 | P308+P313 P201 P202 P280 P405 P501 |
[Rationale for the Classification] Based on (1) to (3), in which reproductive effects of this substance were shown, and based on (1), in which effects on fertility due to toxicity on the male and female reproductive organs were observed, it was classified in Category 1B. New information sources were used and the classification results were changed from the previous classification. [Evidence Data] (1) In a two-generation reproduction study with rats dosed by feeding, parental male animals showed an increase in the number of abnormal spermatozoa at or above 10 ppm (0.8 to 1.1 mg/kg/day) and a decrease in sperm motility, etc. at 15 ppm (1.3 mg/kg/day); parental female animals showed vacuolation and hypertrophy of interstitial gland cells in the ovaries, diffuse fine fatty degeneration of the zona fasciculata of the adrenal glands, etc. at or above 50 ppm (4.7 to 5.6 mg/kg/day); and in both generations, a decrease in the number of live pups (at birth and during lactation period) was observed in males at 15 ppm (P: 1.3 mg/kg/day, F1: 1.6 mg/kg/day) and in females at 300 ppm (P: 28.8 mg/kg/day, F1: 34.5 mg/kg/day); and in F1 generation, lower successful mating rate, etc. were observed in males at 15 ppm (F1: 1.6 mg/kg/day) and females at 300 ppm (F1: 34.5 mg/kg/day) (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013)). (2) In a developmental toxicity study with female rats dosed by gavage on days 6 to 15 of gestation, at a dose (140 mg/kg/day) at which severe maternal toxicity ((1 animal sacrificed in extremis), salivation, reduced body weight gain, a decrease in food consumption, and inhibition of erythrocyte cholinesterase (ChE) activity (20% or higher)) was observed, an increase in the number of resorbed embryos in early and middle gestation periods, a decrease in the number of live fetuses, lower body weight, and increases in external, visceral, and skeletal variations were observed (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013)). (3) In a developmental toxicity study with female rabbits dosed by gavage on days 7 to 19 of gestation, at a dose (200 mg/kg/day) at which severe maternal toxicity (abortions (4 cases), reduced body weight gain, increases in absolute and relative liver weight) was observed, skeletal variations (incomplete ossification of the sternebrae, shortened 15th rib) were observed in fetuses (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013)). [Reference Data, etc.] (4) In the reproduction study of (1) above, a decrease in sperm motility, lower successful mating rate, etc. were observed in rats. As a result of a mechanism examination test, it was suggested that the mechanism of development of reproductive toxicity in males was inhibition of steroid synthesis due to disorders of cholesterol metabolism (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013)). (5) In the EU CLP classification, it was classified as Repr.2 (Classification in EU CLP (Access on June 2020)). |
