2 | Skin corrosion/irritation | Classification not possible |
- |
- | - | Classification not possible due to lack of data. Besides, strong skin irritations were reported in guinea pigs dermally exposed to polychloronaphthalenes (CICAD 34 (2001)). However, the irritations could not be attributed specifically to this substance. Also, it is described that this substance may irritate the skin causing a rash in humans (HSFS (2000)). However, because the original literature could not be confirmed, this data was not adopted. |

3 | Serious eye damage/eye irritation | Classification not possible |
- |
- | - | Classification not possible due to lack of data. Besides, irritation of the eyes was reported in workers exposed to polychloronaphthalenes. Nevertheless, because it was also noted that there had been possible exposure to other chemicals (CICAD 34 (2001)), this data was not adopted. |

8 | Specific target organ toxicity - Single exposure | Classification not possible |
- |
- | - | Classification not possible due to lack of data. There is no data on single exposure of this substance in humans and experimental animals. Besides, while there are descriptions that chlorinated naphthalenes exhibit hepatotoxicity (CICAD 34 (2001), DFGOT Vol. 13 (1997)) and that symptoms in workers exposed to chlorinated naphthalenes included irritation of the eyes, fatigue, headaches, anaemia, haematuria, anorexia, vomiting, severe abdominal pain (CICAD 34 (2001)), none of these had information on the number of exposure times. |

9 | Specific target organ toxicity - Repeated exposure | Category 1 (liver, skin) |
Danger |
H372 | P260 P264 P270 P314 P501 |
There is no information with regard to this substance. Besides, for humans, severe skin reactions (chloracne) and liver disease have both been reported after occupational exposure to chlorinated naphthalenes (CICAD 34 (2001), DFGOT vol. 13 (1997), ACGIH (7th, 2001)). The toxicity varies depending on the degree of chlorination; it is reported that studies in humans and animals had shown that toxicity was dependent on the congener/isomer and that there was agreement in all the studies that the penta- and hexa- isomers were the most toxic (CICAD 34 (2001)). With regard to effects on the skin, it is reported that chloracne was observed with trichloronaphthalenes and higher chlorinated naphthalenes (DFGOT vol. 13 (1997)). It is reported that the incidences and severity of chloracne were less when trichloronaphthalene (usually mixed with some tetrachloronaphthalene) was used rather than when penta- or hexachloronaphthalene was present (ACGIH (7th, 2001)). It is reported that in wire manufacturing plants, contact with a fabric impregnated with hexa- and pentachloronaphthalenes caused chloracne (ACGIH (7th, 2001)). Moreover, it has been reported that after dermal application to volunteers, only Halowax 1014, containing penta- and hexachloronaphthalenes, produced chloracne, and Halowaxes containing mono-, di-, tri-, tetra-, hepta-, and/or octachloronaphthalenes did not (CICAD 34 (2001)). With regard to effects on the liver, as information in which the substance is identified to some extent, a non-fatal case of hepatitis induced by occupational exposure to trichloronaphthalene (tetrachloronaphthalene was probably also present (CICAD 34 (2001)) at 3 mg/m3 has been reported (ACGIH (7th, 2001)). On the other hand, as for higher chlorinated congeners, it is reported that in a workplace environment with concentrations of mixed pentachloronaphthalene and hexachloronaphthalene between 1 and 2 mg/m3, fatal cases of yellow atrophy of the liver occurred (ACGIH (7th, 2001)). As for information on experimental animals, it is reported that in medium-term toxicity experiments performed with technical mixtures of polychloronaphthalenes in rats and guinea pigs, liver damage (mainly enlarged liver cells with increased granularity and vacuolization) etc. were found and the higher chlorinated mixtures appeared to be more toxic (CICAD 34 (2001)). As described above, effects on the liver and skin by chlorinated naphthalenes were observed, and pentachloronaphthalene which has five chlorine atoms and hexachloronaphthalene which has six chlorine atoms were thought to be the major causal substances for the toxicity of chlorinated naphthalenes. However, it was thought that this substance which has eight chlorine atoms, while considered to exhibit less toxicity, also has similar target organs. Therefore, this substance was classified in Category 1 (liver, skin). |

Reliable chronic toxicity data were not obtained. It was classified in Category 4 because it is classified in "Not classified" for acute toxicity, it is poorly water-soluble (water solubility: 8x10^-5 mg/L (PHYSPROP Database, 2009)), not rapidly degradable (a degradation rate by BOD: 0% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, 1975)), and is estimated to be bioaccumulative (BCF was 5600-11800, 4400-8500 respectively when test concentration was set at 0.05 ppm, 0.005 ppm (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, 1975)). | FY2016 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1)) |
