3 | Serious eye damage/eye irritation | Not classified | - | - | - | - | Based on the evidence of slight irritation of the conjunctiva (a mean Draize score of <=1.5), with effects resolving within 3 days, observed in rabbit eye irritation tests (Agricultural Chemical Registration Data (1986)). |
4 | Respiratory sensitization | Classification not possible | - | - | - | - | No data available |
4 | Skin sensitization | Not classified | - | - | - | - | Based on no evidence of sensitization observed in guinea pig skin sensitization tests using the Maximization method, reported in Agricultural Chemical Registration Data (1987, 1990). |
5 | Germ cell mutagenicity | Not classified | - | - | - | - | Based on negative data on in vitro reverse mutation tests (Agricultural Chemical Registration Data (1986)), in vitro chromosome aberration tests (Agricultural Chemical Registration Data (1988)) and in vivo mutagenicity (micronucleus) tests on mouse bone marrow cells (Agricultural Chemical Registration Data (1988)). |

In rat single dose toxicity studies, clinical signs and symptoms including hypoactivity, ataxia, stooping position, decreased grooming, prone position, coma and emaciation were reported (Agricultural Chemical Registration Data (1989)). These effects were observed at dosing levels within the guidance value ranges for Category 2. | |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | In rat 3-month repeated dose toxicity studies, reduced body weight gains and decreased food consumption/food efficiency were observed. However, classification is not possible since no other general symptoms or pathological findings were reported (Agricultural Chemical Registration Data (1988)). |

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 hours LC50=0.00338mg/L of the fish (Carp) (Agricultural Chemical Registration Data, 2004). | |
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 ... |
Since acute toxicity was Category 1 and there was no rapidly degrading (BIOWIN), and since there wasbio-accumulation (log Kow=6.37 (PHYSPROP Database, 2005)), it was classified into Category 1. |
