[Rationale for the Classification] Based on classification results by other organizations (1), it was classified as "Classification not possible" in accordance with the GHS Classification Guidance for the Japanese Government. [Evidence Data] (1) In classification results by domestic and international organizations, it was classified in Group 3 by IARC (IARC Suppl.7 (1987)). |
7 | Reproductive toxicity | * |
- |
- | - |
[Rationale for the Classification] Based on (1)-(3), it was classified as "Not classified." [Evidence Data] (1) In two two-generation reproduction toxicity studies with rats dosed by feeding, no reproductive effects were seen (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013)). (2) In a developmental toxicity test with female rats dosed by gavage during gestational day 6-15, no effect was observed on the fetus even at the dose at which it would be killed in extremis due to deterioration of its general condition was observed in the maternal animals (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013)). (3) No effect was observed on the maternal animals or fetuses in either a developmental toxicity test by gavage administration to female rabbits on gestational day 7-19, or a developmental toxicity test by gavage administration to female rabbits on gestational day 6-18 (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013)). |
8 | Specific target organ toxicity - Single exposure | Category 1 (respiratory organs) |
Danger |
H370 |
P308+P311
P260 P264 P270 P321 P405 P501 |
[Rationale for the Classification] There are no reports on a single exposure to this substance in humans. In experimental animals, as shown in (1) and (2), oral and inhalation exposure to this substance has effects on the gastrointestinal tract and respiratory organs, respectively. Since the effects on the gastrointestinal tract are considered to be associated with irritation, it was not adopted as evidence of the classification. Therefore, it was classified in Category 1 (respiratory organs). Besides, the category was changed from the previous classification by the use of new information sources. [Evidence Data] (1) In a test with a single oral dose of 347-1,037 mg/kg (equivalent to Category 2) of this substance to rats, decreased locomotor activity, lateral position, prone position, hypothermia, lacrimation, nasal discharge, ptosis, eyelid closure, piloerection, diarrhea and loose stool were noted. Deaths were seen at 500 mg/kg or more in males and 417 mg/kg or more in females, and at necropsy, focal and diffuse reddish changes in the mucous membrane of the glandular stomach were observed in the dead animals (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013), A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2013)). (2) In a 4-hour single inhalation test with rats exposed to the dust of this substance, gasping, rales, nasal discharge, tremors, and abnormality of the cornea were observed at 0.94 mg/L. In another 4-hour single inhalation exposure test with rats, eye stimulation, dyspnea, nasal discharge and salivation were observed. In necropsy, lung congestion was observed at 0.95 mg/L or higher, and pulmonary emphysema and pleural effusion were observed at 1.21 mg/L or higher (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013), A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2013)). The concentrations at which these effects were observed correspond to Category 2 or near the upper limit of Category 1. [Reference Data, etc.] (3) Regarding copper (CAS RN 1317-38-0), there are reports that digestive symptoms (nausea, vomiting, gastric pain, etc.) were observed in humans ingesting drinking water containing high copper concentrations and that inhalation exposure causes effects on the respiratory organs (respiratory tract irritation) (EHC 200 (1998), ACGIH (7th, 2001), ATSDR (2004)). Based on these pieces of information, copper was classified in Category 1 (digestive system) and Category 3 (respiratory tract irritation) in the 2013 GHS classification. |
9 | Specific target organ toxicity - Repeated exposure | Category 2 (liver) |
Warning |
H373 |
P260
P314 P501 |
[Rationale for the Classification] Based on (1)-(4), as a result of oral administration to experimental animals, an effect on the liver was observed within the range of Category 2, therefore it was classified in Category 2 (liver). Regarding effect on the gastrointestinal tract, it was not adopted as a target organ because this is considered to be an effect associated with the irritation of this substance. As a result of examination using a new information source, the classification result was changed from the previous classification. [Evidence Data] (1) As a result of a 90-day study by gavage administration to dogs at doses of 1-50 mg/kg/day, vomiting, loose stools, bleeding in the submucosal tissue in the stomach were observed at or above 5 mg/kg/day (within the range of Category 1), and hyperemia of the submucosal tissue in the duodenum the submucous membranes was noted at 50 mg/kg/day (within the range of Category 2) (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013)). (2) As a result of oral administration by capsules at doses of 1-25 mg/kg/day to dogs for 1 year, loose stools and vomiting were observed at or above 5 mg/kg/day or more (within the range of Category 1), while diarrhea, decreased body weight gain, an increase in bilirubin, etc. were noted at 25 mg/kg/day (within the range of Category 2). (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013)). (3) As a result of a 2-year carcinogenicity study in rats dosed by feeding, decreased body weight gain and chronic inflammation of the liver were observed at a dose of 2,000 ppm (male/female: 96/125 mg/kg/day, male: within the range of Category 2, female: more than Category 2) (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013)). (4) As a result of a 2-year study with dogs dosed by feeding at doses of 10-3,000 ppm, there is a report that increases in alpha 1 globulin and beta globulin, etc. were observed at or above 1,000 ppm (male/female: 35/30 mg/kg/day, within the range of Category 2), and decreased body weight gain and food consumption, increased ALT and AST, lymph node edema, dilatation of medullary sinus of lymph node, submucosal edema of the stomach, small intestine and large intestine, pancreatic edema, alveolar foamy macrophage, hepatocyte necrosis, interstitial nephrosis and so on were noted at 3,000 ppm (male/female: 96/103 mg/kg/day, male: within the range of Category 2, female: more than Category 2), but in this study, in the high dose group (three each for male and female for the group necropsied at the end, one each for male and female for the interim necropsy group), in the group necropsied at the end, two males were killed in extremis, one female died, and one female was killed in extremis, and one each for male and female animals survived at the end of the treatment (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2013), A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2013)). |
