|---|---|---|---|---|---|---|---|
| 1 | Acute toxicity （Oral） | Classification not possible | - | - | - | - | Classification not possible due to lack of data. As relevant information, the mortality is 62% at 500 mg/kg in rabbits (CICAD 34 (2001)). |

|
Danger | H372: Cause damage to organs through prolonged or repeated exposure (liver, skin, systemic toxicity) |
P260: Do not breathe dust/fume/gas/mist/vapours/spray. P264: Wash ... thoroughly after handling. P270: Do not eat, drink or smoke when using this product. P314: Get medical advice/attention if you feel unwell. P501: Dispose of contents/container to ... |
For chlorinated naphthalene (polychloronaphthalene), there is a report that liver damage such as acute liver necrosis, hepatitis and jaundice, and skin damage were found in workers after repeated exposure (DFGOT vol. 13 (1999)). Symptoms reported in workers exposed to the substance included irritation of the eyes, fatigue, headache, anaemia, and haematuria (CICAD 34 (2001)). Systemic effects resulting in liver disease were reported only from the inhalation of fumes (CICAD 34 (2001)). At least 10 deaths were reported from acute atrophy of the liver (CICAD 34 (2001)). Severe skin reactions (chloracne) were reported after skin contact (CICAD 34 (2001)). Based on the information, the substance was classified into Category 1 (liver, skin, systemic toxicity). |
| 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） | Not classified | - | - | - | - | Classified into Not classified since it is suggested not to show the toxicity at the concentration of water solubility (0.00008 mg/L (PHYSPROPD Database, 2010)) from its 96h-LC50 >560 mg/L for fish (Sheepshead minnow) (CICAD 34, 2001) and 96h-LC50 >500 mg/L for Crustacea (Mysid shrimp) (CICAD34, 2001). |
| 11 | Hazardous to the aquatic environment （Long-term） | Category 4 | - | - | H413: May cause long lasting harmful effects to aquatic life |
P273: Avoid release to the environment. P501: Dispose of contents/container to ... |
Classified into Category 4 since it is estimated not to be rapidly degradable (BIOWIN) and to be bioaccumulative (log Kow = 8.5 (PHYSPROP Database, 2009) though it is non-water soluble and acute toxicity has not been reported at or lower concentration than water solubility. |
| 12 | Hazardous to the ozone layer | Classification not possible | - | - | - | - | This substance is not listed in Annexes to the Montreal Protocol. |
