2 | Skin corrosion/irritation | Category 2 |
Warning |
H315 | P302+P352 P332+P313 P362+P364 P264 P280 P321 |
[Rationale for the Classification] It was classified in Category 2 from (1) - (3). Because rationale data for the previous classification could not be confirmed, based on newly obtained data in (1) - (3), the classification result was changed. [Evidence Data] (1) In a skin irritation test with rabbits, very slight to well-defined erythema was observed in 2/6 animals at 1 hour after removal of patches. Well-defined to moderate to severe erythema was found after 24, 48, and 72 hours and disappeared after 7 days. Very slight to severe edema was present in all animals at 1 hour after removal of patches and persisted through 72 hours but disappeared on day 7. The primary irritation index (PII) was 4.8, and it was considered as a slight to moderate irritant (JMPR Addendum (2011)). (2) It was a moderate irritant in a skin irritation test with rabbits according to EPA OPP 81-5 (EPA Pesticides RED (1998)). (3) In humans, short-time exposure irritates the eye and skin and causes erythema. Long-term or repeated contact with the skin may cause dermatitis (Environmental Risk Assessment for Chemical Substances vol. 4, Tentative Hazard Assessment Sheet (Ministry of the Environment, 2005)). [Reference Data, etc.] (4) In skin irritation tests with rabbits using emulsion (active ingredient 51%) and wettable powder (active ingredient 35%) of this substance, it was judged as a moderate to severe irritant (Agricultural Chemicals Times supplement "Agricultural chemicals technology information" No. 12 (Japan Crop Protection Association, 1992)). |

3 | Serious eye damage/eye irritation | Category 2B |
Warning |
H320 | P305+P351+P338 P337+P313 P264 |
[Rationale for the Classification] It was classified in Category 2B from (1) - (3). Because it was classified in Category 1 based on the result in formulation (wettable powder) in the previous classification, the classification result was changed based on the result in this substance itself. [Evidence Data] (1) In an eye irritation test with rabbits (eyes were irrigated at 24 hours after application), there were no effects on the cornea and iris, but conjunctival effects were observed in 6/6 animals after 1 and 24 hours and 5/6 animals after 48 hours and disappeared within 72 hours, and this substance was considered to be a slight to moderate eye irritant (JMPR Addendum (2011)). (2) It was a moderate irritant in an eye irritation test with rabbits according to EPA OPP 81-4 (EPA Pesticides RED (1998)). (3) In humans, short-term exposure irritates the eye and skin and produces erythema (Environmental Risk Assessment for Chemical Substances vol. 4, Tentative Hazard Assessment Sheet (Ministry of the Environment, 2005)). [Reference Data, etc.] (4) In an eye irritation test with rabbits using emulsion (active ingredient 51%) of this substance, changes were seen in the cornea, conjunctiva, and iris but disappeared by 7 days (Agricultural Chemicals Times supplement "Agricultural chemicals technology information" No. 12 (Japan Crop Protection Association, 1992)). (5) In an eye irritation test with rabbits using wettable powder (active ingredient 35%) of this substance, changes were observed in the cornea, conjunctiva, and iris, and reactions in the conjunctiva and iris disappeared by 14 days, but changes in the cornea persisted after 21 days (Agricultural Chemicals Times supplement "Agricultural chemicals technology information" No. 12 (Japan Crop Protection Association, 1992)). |

4 | Skin sensitization | Classification not possible |
- |
- | - | [Rationale for the Classification] There were descriptions in (1) - (3), but because contradicting data were mixed, and a clear conclusion could not be obtained, the classification was not possible. Because data that contradicted the previous classification were obtained, the classification result was changed. [Evidence Data] (1) It was reported to be a slight to moderate sensitizer in a skin sensitization test with guinea pigs (Buehler test) (JMPR (2011)). (2) In a skin sensitization test with guinea pigs by a modified Buehler test (induction: 10-time applications of a 4.2% solution, 6 hours/application, 3 times/week, 3.5 weeks, challenge: an 11.7% solution, 2 weeks after the last induction, rechallenge 1 week later), erythema was observed in part of the animals, but no clear difference from the control group was seen, and no clear conclusion on sensitization was reached (JMPR Addendum (2011)). (3) It was a non-sensitizer in a skin sensitization test with guinea pigs according to EPA OPP 81-6 (EPA Pesticides RED (1998)). [Reference Data, etc.] (4) It was judged as a slight sensitizer in skin sensitization tests with guinea pigs using emulsion (active ingredient 43.8%) and wettable powder (active ingredient 36.2%) of this substance (Agricultural Chemicals Times supplement "Agricultural chemicals technology information" No. 12 (Japan Crop Protection Association, 1992)). |

5 | Germ cell mutagenicity | Not classified |
- |
- | - | [Rationale for the Classification] It was classified as "Not classified" from (1), (2). [Evidence Data] (1) As for in vivo, it was reported to be negative in a chromosomal aberration test with bone marrow cells after oral administration to rats (EPA Pesticides RED (1998), JMPR addendum (2011), HSDB (Access on May 2020), Agricultural Chemicals Times supplement "Agricultural chemicals technology information" No. 12 (Japan Crop Protection Association, 1992)). (2) As for in vitro, it was reported to be negative in a bacterial reverse mutation test (EPA Pesticides RED (1998), JMPR addendum (2011), HSDB (Access on May 2020), CEBS (Access on May 2020), Agricultural Chemicals Times supplement "Agricultural chemicals technology information" No. 12 (Japan Crop Protection Association, 1992)). As for test systems using cultured mammalian cells, it was reported to be negative in a chromosomal aberration test, negative in a gene mutation test (EPA Pesticides RED (1998), JMPR addendum (2011), HSDB (Access on May 2020)), and negative in a sister chromatid exchange test (JMPR addendum (2011)). |

6 | Carcinogenicity | Category 2 |
Warning |
H351 | P308+P313 P201 P202 P280 P405 P501 |
[Rationale for the Classification] From (1) - (3), based on EPA's classification result, which was done later (1998) than IARC (1987), it was classified in Category 2. By the study using new information sources, the classification result was changed. [Evidence Data] (1) As for classification results by domestic and international organizations, it was classified in Group 3 by IARC (IARC Sup7 (1987)) and Group C (possible human carcinogen) by EPA (EPA Pesticides RED (1998)). (2) In carcinogenicity tests by 78-week diet administration of this substance to male and female rats and mice, significant increases in the incidences of hepatocellular carcinoma and hepatocellular adenoma and carcinoma (combined) were observed in male mice. No increase in tumor incidence was seen in female mice and male and female rats (NTP TR90 (1978), IARC 30 (1983), EPA Pesticides RED (1998)). (3) In a combined chronic toxicity/carcinogenicity study by 2-year diet administration of this substance to male and female rats, no treatment-related increases in tumor incidence were observed (JMPR (2011), EPA Pesticides RED (1998)). |

7 | Reproductive toxicity | Category 2 |
Warning |
H361 | P308+P313 P201 P202 P280 P405 P501 |
[Rationale for the Classification] Based on (1), effects on fertility were observed at a dose of parental toxicity. Therefore, it was classified in Category 2 in accordance with the GHS Classification Guidance for the Japanese Government. A new information source was used and the classification results were changed from the previous classification. [Evidence Data] (1) In a two-generation reproduction toxicity test with rats dosed by feeding, lower survival rate of offspring was observed at a dose at which parental toxicity (reduced body weight gain, a decrease in food consumption, increases in the incidence of hypertrophy and/or vacuolation of the adrenal cortex, hypertrophy of interstitial cells in the ovary, and degeneration of hepatocytes) was observed (Environmental Risk Assessment for Chemical Substances Vol. 4, Tentative Hazard Assessment Sheet (Ministry of the Environment, 2005), JMPR (1992), JMPR addendum (2011)). [Reference Data, etc.] (2) In a developmental toxicity study with female rats dosed by gavage on days 6-15 of gestation, no effect was observed in fetuses even at a dose at which maternal toxicity (excessive salivation, reduced body weight gain, centrilobular hepatocyte hypertrophy, etc.) was observed (Environmental Risk Assessment for Chemical Substances Vol. 4, Tentative Hazard Assessment Sheet (Ministry of the Environment, 2005), Agricultural Chemicals Times supplement "Agricultural chemicals technology information" Vol. 12 (Japan Crop Protection Association, 1992), JMPR (1992), JMPR addendum (2011)). (3) In a developmental toxicity study with female rabbits dosed by gavage on days 7-19 of gestation, miscarriage was observed at a dose at which maternal toxicity (reduced body weight, eosinophilic and hyaline material in centrilobular hepatocytes) was observed, but no effect was observed in offspring (Environmental Risk Assessment for Chemical Substances Vol. 4, Tentative Hazard Assessment Sheet (Ministry of the Environment, 2005), Agricultural Chemicals Times supplement "Agricultural chemicals technology information" Vol. 12 (Japan Crop Protection Association, 1992), JMPR (1992), JMPR addendum (2011)). |

[Rationale for the Classification] Based on (1) to (3), it was classified in Category 1 (central nervous system) and Category 3 (narcotic effects). A new information source was used and the classification results were changed from the previous classification. [Evidence Data] (1) Such acute symptoms as reddening of the eye or skin, confusion, convulsions, coughing, dizziness, headache, nausea, vomiting, a feeling of weakness, and disorientation appeared, and after oral ingestion, abdominal pains and diarrhea were also observed (Environmental Risk Assessment for Chemical Substances Vol. 4, Tentative Hazard Assessment Sheet (Ministry of the Environment, 2005)). (2) In one person who orally ingested this substance (ingested amount unknown), nausea, dizziness, and vomiting were observed. It was reported that in three persons who were exposed by inhalation to this substance (concentration unknown), dizziness, and a feeling of weakness were observed, and vomiting in two of them, and nasal obstruction in one of them also occurred (Environmental Risk Assessment for Chemical Substances Vol. 4, Tentative Hazard Assessment Sheet (Ministry of the Environment, 2005)). (3) In a case of a 12-year-old boy exposed to this substance via dermal route by accidentally falling into a pool of a spilled undiluted solution of formulation of this substance (470 g/L), such initial symptoms as nausea, dizziness, disorientation, confusion, lethargy, and headache appeared, and lateral nystagmus and a reduced sense of balance were also observed, but these symptoms disappeared in 3 weeks. As a result of a neuropsychological test 8 months after the exposure, impairment of cognitive functions, such as auditory reflex, immediate memory, and ability to inhibit an inappropriate response, was observed, and the cognitive impairment and emotional disturbance continued for 18 months (Environmental Risk Assessment for Chemical Substances Vol. 4, Tentative Hazard Assessment Sheet (Ministry of the Environment, 2005)). |

Danger Warning |
H372 H373 |
P260 P264 P270 P314 P501 |
[Rationale for the Classification] Based on (1) to (5), it was classified in Category 1 (liver, adrenal gland) and Category 2 (nervous system). In a test with rats in (1), effects on the thyroid were also observed within the range for Category 1, but they were determined to be secondary changes (physiological changes of the thyroid axis related to hepatic enzyme induction) of effects on the liver, and the thyroid was not considered as a target organ. In a test with dogs in (3), inhibition of the central nervous system, effects on the heart and testis, and oligospermia were also observed within the range for Category 2, but these effects were not observed in a longer test in (5), and those organs were not considered as target organs. The data for the rationale for the previous classification could not be referred to, and as a result of review using the information of the sources in List 1 and 2, the classification results were changed from the previous classification. [Evidence Data] (1) In a 13-week test with rats dosed by feeding, thyroid follicular cell hypertrophy in males at or above 10 ppm (males/females: 0.64/0.78 mg/kg/day, within the range for Category 1); enhanced hepatic mixed function oxidase (MFO) activity and hepatocyte hypertrophy in males and females at or above 100 ppm (males/females: 6.49/7.84 mg/kg/day, within the range for Category 1); an increase in liver weight, a decrease in blood corticosterone concentrations, and vacuolation of the adrenal cortex in males and females, and thyroid follicular cell hypertrophy in females at or above 500 ppm (males/females: 32.01/36.11 mg/kg/day, within the range for Category 2); and deaths (5/10 males, 8/10 females), ataxia, and lethargy in males and females at 1,500 ppm (males/females: 95.84/105.91 mg/kg/day, within the range for Category 2 for males, and exceeding Category 2 for females) were observed (EPA Pesticides RED (1998), Environmental Risk Assessment for Chemical Substances Vol. 4, Tentative Hazard Assessment Sheet (Ministry of the Environment, 2005), JMPR addendum (2011)). (2) In a 13-week test with mice dosed by feeding, enhanced hepatic MFO activity in males and females, and an increase in liver weight in females at or above 125 ppm (males/females: 18.2/29.3 mg/kg/day, within the range for Category 2); hepatocyte hypertrophy in males and females, and enhanced GTP activity in females at or above 250 ppm (males/females: 38.2/56.2 mg/kg/day, within the range for Category 2); and adrenal cortical cell hypertrophy, hepatocyte necrosis, and vacuolation in males and females, and degeneration of the kidney in females at or above 500 ppm (males/females: 84.4/108.0 mg/kg/day, within the range for Category 2 for males, and exceeding Category 2 for females) were observed (Same as above). (3) In a 3-month test with dogs dosed by feeding, a decrease in cortisol release in response to adrenocorticotropic hormone (ACTH) administration, and oligospermatogenesis in males at or above 100 ppm (males/females: 3.3/3.4 mg/kg/day, within the range for Category 1); labored breathing, inactivity, dehydration, diarrhea, incoordination, excessive salivation, and prolongation of QT interval in males and females, an increase in liver weight in males, and increases in ALT and ALP activity in females at or above 300 ppm (males/females: 9.9/9.8 mg/kg/day, within the range for Category 1); and histopathological changes in the liver, testis, and heart in males and females, and an increase in liver weight in females at 1,000 ppm (males/females: 26/27 mg/kg/day, within the range for Category 2) were observed (EPA Pesticides RED (1998), JMPR addendum (2011)). (4) As a result of a 24-month test with rats dosed by feeding, enhanced hepatic MFO activity, centrilobular hypertrophy, vacuolation, and acidophilic changes of hepatocytes, and diffuse vacuolation of the adrenal cortex zona fasciculata and reticularis in males and females, an increase in liver weight in males at or above 50 ppm (males/females: 2.23/2.69 mg/kg/day, within the range for Category 1); and reduced body weight gain in males and females, and an increase in liver weight, focal hepatocyte hyperplasia, and chronic cystitis in females at 250 ppm (males/females: 11.34/14.26 mg/kg/day, within the range for Category 2) were observed (EPA Pesticides RED (1998), Environmental Risk Assessment for Chemical Substances Vol. 4, Tentative Hazard Assessment Sheet (Ministry of the Environment, 2005), JMPR addendum (2011)). (5) As a result of a 52-week test with dogs dosed by feeding, hepatocyte hypertrophy, toxic effects in the adrenal gland, a slight increase in ALP activity, a decrease in albumin concentration, and reduced cortisol release in an ACTH stimulation test were observed in males and females at 180 ppm (males/females: 5.71/5.42 mg/kg/day, within the range for Category 1) (IARC (1983), EPA Pesticides RED (1998), Environmental Risk Assessment for Chemical Substances Vol. 4, Tentative Hazard Assessment Sheet (Ministry of the Environment, 2005), JMPR addendum (2011)). [Reference Data, etc.] (6) In 28-day dermal toxicity tests with rats and rabbits, only a decrease in body weight and centrilobular hepatocyte hypertrophy in the liver (rats) were observed at doses of which converted guidance values corresponded to Category 2 (rats: 12 mg/kg/day; rabbits: 19 mg/kg/day) (EPA Pesticides RED (1998)). |
