After occlusive application of 0.5 mL of this substance to rabbits for 4 hours, severe erythema, edema, and corrosivity were observed, recovery was not observed for 14 days, and it was judged to be strongly irritating and corrosive (Agricultural Chemicals Times supplement vol.10 "Agricultural chemicals technology information"). In addition, there are descriptions that this substance causes redness and pain if it comes into contact with the skin (Environmental Risk Assessment for Chemical Substances Vol.10 (Ministry of the Environment, 2012)), and that it was a skin irritant to humans (ACGIH (7th, 2001)). From the above, based on the description that "it is corrosive," it was classified in Category 1. The data from Agricultural Chemicals Times supplement "Agricultural chemicals technology information" was added, and the category was changed. Besides, this substance was classified as "R38" in the EU DSD classification, and as "H315 Skin Irrit 2" in the EU CLP classification. |

5 | Germ cell mutagenicity | Classification not possible |
- |
- | - | It was classified as "Classification not possible" because it was not possible to classify a substance as "Not classified" according to the revised GHS classification guidance for the Japanese government. As for in vivo, it was negative in a micronucleus test with mouse erythrocytes and an unscheduled DNA synthesis test with rats (Environmental Risk Assessment for Chemical Substances Vol.10 (Ministry of the Environment, 2012)). As for in vitro, although it was positive in bacterial reverse mutation tests, and a chromosome aberration test and a sister chromatid exchange test with cultured mammalian cells, it was negative in a micronucleus test with human cells, a mouse lymphoma test, and an unscheduled DNA synthesis test with rat hepatocytes (Environmental Risk Assessment for Chemical Substances Vol.10 (Ministry of the Environment, 2012), DFGOT vol. 6 (1994), Agricultural Chemicals Times supplement vol.10 "Agricultural chemicals technology information" (1992), NTP DB (Access on July 2014)). Since the results were negative in vivo, it was judged that there was no in vivo mutagenicity. |

No effects on fertility were observed in a two-generation reproduction toxicity test with rats by the inhalation route (Environmental Risk Assessment for Chemical Substances Vol.10 (Ministry of the Environment, 2012)). In teratogenicity tests with rats and rabbits by the inhalation route, only slight effects were observed in the fetuses even at doses where severe toxicities including death were observed in maternal animals (Environmental Risk Assessment for Chemical Substances Vol.10 (Ministry of the Environment, 2012)). From the above, in addition to teratogenicity, new information on fertility in parental animals was obtained. As a result, since no effect on teratogenicity and fertility in parental animals was observed, it was classified as "Not classified." |

In humans, this substance caused strong respiratory tract mucosal irritation, and by inhalation exposure, lacrimation, runny nose, cough, headache, irritation of the upper airways with dyspnea, bronchitis and death from pulmonary edema might be caused. In addition, by the inhalation or oral exposure abdominal pain, cough, diarrhea, dizziness, headache, nausea, sore throat, vomiting, and weakness occurred (Environmental Risk Assessment for Chemical Substances Vol.10 (Ministry of the Environment, 2012), OEL Documentations (Japan Society For Occupational Health (JSOH), 1968), EPA Pesticide Fact Sheet (2008), ACGIH (7th, 2001), DFGOT vol. 6 (1994)). Moreover, methemoglobin formation and hemolysis were reported in those severely exposed (DFGOT vol.6 (1994)). As for experimental animals, in rats or mice, severe injury of the respiratory tract was observed, decreased respiratory rate, ulceration and necrosis of the respiratory epithelium, bronchitis, pulmonary edema, congestion and hemorrhage of the lungs, cyanosis, dyspnea and death were reported, and there is a description that the cause of death was attributed to respiratory failure (ACGIH (7th, 2001), DFGOT vol. 6 (1994), PATTY (6th, 2012)). These findings were within the guidance value range corresponding to Category 1. Besides, there were no findings showing the effects on the nervous system described in the previous classification. From the above, it was classified in Category 1 (respiratory organs, hemal system). |
9 | Specific target organ toxicity - Repeated exposure | Category 1 (respiratory organs, liver, haemal system) |

There is a description that a family exposed to this substance in indoor air, which was used in the basement of a house to exterminate bats and was a source, developed irritation symptoms such as coughing, lacrimation and runny noses within 1 week, they became more severe in a smoker, and bronchitis and sinusitis with redness and edema of the nasal and pharyngeal mucosa were observed (DFGOT vol. 6 (1994)). However, it is described that no findings on chronic exposure to this substance were obtained in the investigation conducted by the Ministry of the Environment (Environmental Risk Assessment for Chemical Substances Vol.10 (Ministry of the Environment, 2012)). As the findings in experimental animals, by the oral route, tests in which rats were administered by gavage or feeding for 13 weeks, 78 weeks, or 2 years, and tests in which mice were administered by gavage for 78 weeks and dogs were administered by gavage (capsule) for 1 year were conducted. And, effects on the liver (vacuolation of periportal hepatocytes) in rats, and on the digestive system (vomiting, diarrhea) and on the hemal system (decreases in erythrocyte parameters (MCV, MCHC)) in dogs at doses corresponding to Category 1 (1-5 mg/kg/day), tissue changes in the forestomach (chronic inflammation, hyperkeratosis, acanthosis) in rats and mice, and effects on the hemal system (decreased hemoglobin concentrations and hematocrit values) and on the respiratory system (inflammation and congestion of the lungs) in rats were observed at doses corresponding to Category 2 (20-33 mg/kg/day) (Environmental Risk Assessment for Chemical Substances Vol.10 (Ministry of the Environment, 2012), NTP TR 65 (1978)). Among these, digestive system symptoms, tissue changes in the forestomach seemed to be due to irritation by this substance, and the digestive system was not included in the target organ. As for the inhalation route, 13-week inhalation exposure tests and long-term exposure tests with rats and mice (107 weeks for rats, 78 weeks for mice) using this substance (the vapour) were conducted. In all test results, although extensive effects on the respiratory organs (inflammatory changes, degeneration, necrosis, hyperplasia and fibrosis of the epithelial cells in the nasal cavity, trachea, bronchi and lung, alveolar proteinosis, etc.) were observed from the concentration range of Category 1 (0.3-1.58 ppm (0.002-0.011 mg/L/6 hr)) (Environmental Risk Assessment for Chemical Substances Vol.10 (Ministry of the Environment, 2012), PATTY (6th, 2012)), there was no common effect as a systemic effect, and the effects were considered to be limited to local areas by inhalation exposure. From the above, based on hazardous findings in experimental animals, it was classified in Category 1 (respiratory organs, liver, hemal system). Besides, the previous classification was based on the information sources in List 2 and 3, and the findings that "central nervous system" should be the target organ were not obtained from the information source of List 1, used for classification this time, but the findings that "liver" should be included in the target organ were newly obtained. |
