[Rationale for the Classification] Based on (1), it was classified in Category 1B. Also, based on the new findings, the classification result was changed. [Evidence Data] (1) It was reported that, in a maximization test (OECD TG 406, intradermal induction: 5% solution) with guinea pigs (n=10), the positive rate was 89% (8/9 animals, one animal died during the process) (ECHA RAC Opinion (2011), CLH Report (2009)). [Reference Data, etc.] (2) The results were negative by the Buehler method, but the results were positive by the maximization method (Risk Assessment Report (Pesticide) (Food Safety Commission of Japan, 2019), JMPR (2009)). (3) It was reported that, in a skin sensitization test (dermal administration: undiluted solution) by the Buehler method with guinea pigs (n=10), no dermal sensitization was observed (A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2012)). (4) In the EU, it was classified in Skin Sens. 1B (EU-CLP Classification Results (Accessed Jan. 2022)). |

[Rationale for the Classification] Based on (1) to (3), an increase in the incidence of urinary bladder tumors was suggested, but since it was a result only for one animal species and one sex (male mice) derived from a single test, it was considered to be limited evidence of carcinogenicity and insufficient for classification in Category 1B, and therefore, it was classified in Category 2. It was classified based on the new information source. [Evidence Data] (1) In a carcinogenicity study with mice dosed by feeding for two years, at 50 to 600 ppm (7.6 to 92 mg/kg/day (males), 10 to 110 mg/kg/day (females)), a significant increase or a trend towards an increase in the incidence of liver tumors (combined hepatocellular adenomas and adenocarcinomas) in males, lung tumors (combined bronchiolar/alveolar adenomas and bronchiolar/alveolar carcinomas) in females, and urinary bladder tumors (leiomyosarcomas) in males was observed (JMPR (2009)). (2) As a result of re-evaluation by an expert panel of pathologists, it was concluded that the liver tumors and lung tumors in (1) were not related to the administration. Also, as for (2), the Food Safety Commission of Japan judged that the liver tumors were not the effects of the administration of the test substance because there was no statistically significant increase and they were not accompanied by precancerous lesions, either, and that the lung tumors were not the effects of the administration of the test substance because the strain of mice (Swiss Webster) used was a strain in which lung tumors of this type occurred most frequently, and the increased incidence in the dose group was also within the background data and was not dose-dependent, etc. (JMPR (2009), Risk Assessment Report (Pesticide) (Food Safety Commission of Japan, 2019)). (3) As for the increase in the incidence of urinary bladder tumors (leiomyosarcomas) observed in a high-dose group of male mice in (1), in the above re-evaluation by an expert panel of pathologists, the JMPR judged that the urinary bladder tumors in mice were benign, probably vascular in origin, occurred predominantly in males, apparently occurred only in mice and had no relevance for humans. On the other hand, the Food Safety Commission of Japan concluded that an increase in the incidence of leiomyosarcomas (submucosal tumors) was observed in the urinary bladder of male mice, but it was difficult to consider the mechanism of tumor formation as genotoxic, and that it was considered possible to set a threshold for assessment, and it did not deny the relationship between urinary bladder tumors and the administration of the test substance (JMPR (2009), Risk Assessment Report (Pesticide) (Food Safety Commission of Japan, 2019)). (4) The EU concluded that the possibility that both urinary bladder tumors and liver tumors observed in male mice were related to the administration of the test substance could not be ruled out, and there was no clear evidence that they had no relevance for humans, and it adopted these tumor incidences as the rationale for the carcinogenicity classification by the EU (ECHA RAC Opinion (2011)). (5) As for the classification results by domestic and international organizations, the EPA classified this substance in Group C (Possible Human Carcinogen) (EPA OPP Annual Cancer Report (2020)), and the EU classified it in Carc. 2 (EU-CLP Classification Results (Accessed Jan. 2022)). [Reference Data, etc.] (6) In a carcinogenicity study with rats dosed by feeding for two years, at 12 to 200 ppm (2.3 to 9.7 mg/kg/day (males), 3.0 to 12.7 mg/kg/day (females)), there was no increase in the incidence of tumors up to the highest dose of 200 ppm at which general toxicity (tremor, decreased body weight gain) appeared (Risk Assessment Report (Pesticide) (Food Safety Commission of Japan, 2019), JMPR (2009), ECHA RAC Opinion (2011)). |
