4 | Respiratory sensitization | Classification not possible | - | - | - | - | No data |
4 | Skin sensitization | Category 1 | Warning | H317: May cause an allergic skin reaction |
P302+P352: IF ON SKIN: Wash with plenty of soap and water. P333+P313: If skin irritation or rash occurs: Get medical advice/attention. P261: Avoid breathing dust/fume/gas/mist/vapours/spray. P272: Contaminated work clothing should not be allowed out of the workplace. P280: Wear protective gloves/protective clothing/eye protection/face protection. P321: Specific treatment (see ... on this label). P363: Wash contaminated clothing before reuse. P501: Dispose of contents/container to ... |
Classified as Category 1 because the skin sensitization test using guinea pigs showed 100% positive rate (agrochemical abstract). | |
5 | Germ cell mutagenicity | Category 1B | Danger | H340: May cause genetic defects |
P308+P313: IF exposed or concerned: Get medical advice/attention. P201: Obtain special instructions before use. P202: Do not handle until all safety precautions have been read and understood. P281: Use personal protective equipment as required. P405: Store locked up. P501: Dispose of contents/container to ... |
The dominant lethal test using rats, which is an in vivo multi-generation mutagenicity test using germ cells, is negative (Agricultural-Chemicals abstracts). And the experts investigated and confirmed the validity of the classification as Category 2 in EU and the classification of the substance's germ cell mutagenicity as Category 3A in MAK (Germany) (MAK/BAT, 2005), based on the data indicating that aneuploidy is induced in the test using mouse oocytes, which is an in vivo mutagenicity test using germ cells (Mailhes JB, & Aardema MJ; 1992). So the substance was classified as Category 1B | |
6 | Carcinogenicity | Not classified | - | - | - | - | It is classified into A4 (ACGIH 7th, 2001) according to ACGIH and is classified into Group C according to EPA. So it was set as the outside of Category. |
7 | Reproductive toxicity | Category 1B | Danger | H360: May damage fertility or the unborn child |
P308+P313: IF exposed or concerned: Get medical advice/attention. P201: Obtain special instructions before use. P202: Do not handle until all safety precautions have been read and understood. P281: Use personal protective equipment as required. P405: Store locked up. P501: Dispose of contents/container to ... |
Since there was the increase of the average of appearance ratio of malformation per litter, and hydrocephalus in the dose no maternal toxicity in the 7-to-16-day-pregnant oral administration to rat (Agricultural-Chemicals abstracts), it is classified into Category 1B. Moreover, there is the description that there was malformation of embryo in the dose no general toxicity to maternal animals in pregnant rat and mouse administration test (JMPR (1995)). | |
8 | Specific target organ toxicity - Single exposure | Not classified | - | - | - | - | Since significant toxicity was not observed in taking orally and the transdermal medication examination using rat and mouse (Agricultural-Chemical abstracts), it was out of the Category. |
9 | Specific target organ toxicity - Repeated exposure | Category 2 (liver) | Warning | H373: May cause damage to organs through prolonged or repeated exposure (liver) |
P260: Do not breathe dust/fume/gas/mist/vapours/spray. P314: Get medical advice/attention if you feel unwell. P501: Dispose of contents/container to ... |
Since the effects on the liver was observed in the three-month oral feeding administration tests with this medicine 50% dosage using dog and the two-year oral feeding administration tests using dog (Agricultural Chemicals abstracts) within the dosage of the guidance value range of Category 2, it was classified into Category 2 (liver). | |
10 | Aspiration hazard | Classification not possible | - | - | - | - | No data available |
Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
---|---|---|---|---|---|---|---|
11 | Hazardous to the aquatic environment (Acute) | Category 1 | Warning | H400: Very toxic to aquatic life |
P273: Avoid release to the environment. P391: Collect spillage. P501: Dispose of contents/container to ... |
It was classified into Category 1 from 96-hour LC50=0.012mg/L of fishes (American catfish) (EHC148, 1993). | |
11 | Hazardous to the aquatic environment (Long-term) | Category 1 | Warning | H410: Very toxic to aquatic life with long lasting effects |
P273: Avoid release to the environment. P391: Collect spillage. P501: Dispose of contents/container to ... |
Classified into Category 1, since acute toxicity was Category 1, not rapidly degrading (half life of carbendazim (hydrolysis product) was two months (under aerobic condition) and 25 months (under anaerobic condition) in water (EHC148, 1993)), though supposed less bioaccumulative(log Kow=2.12 (PHYSPROP Database, 2005)). |
