Description of key information
Short term toxicity to fish:
The short-term toxicity of the 1,4-Bis(ethenyl)benzene; p-Divinylbenzene (CAS no.105-06-6 ) to fish is predicted using EPI Suite ECOSAR version 1.10. On the basis of effects observed in a static freshwater system during a 96 hr exposure, the effect concentration (EC50) for the substance is estimated to be 2.602 mg/L. Based on this value, it can be concluded that the test chemical can be considered as toxic to fish at environmentally relevant concentrations and can be considered as classified in aquatic chronic category 2 as per the CLP classification criteria.
Long term toxicity to fish:
The study need not to be conducted as the solubility of test material in water is highly insoluble . Hence, indicating aquatic toxicity unlikely to occure.
Short term toxicity to aquatic invertebrate:
The short-term toxicity of the 1,4-Bis(ethenyl)benzene; p-Divinylbenzene (CAS no.105-06-6 ) to Daphnia Magna is predicted using EPI Suite ECOSAR version 1.10. On the basis of effects observed in a static freshwater system during a 48 hr exposure, the effect concentration (EC50) for the substance is estimated to be 1.744 mg/L. Based on this value, it can be concluded that the test chemical can be considered as toxic to Daphnia Magna at environmentally relevant concentrations and can be considered as classified in aquatic chronic category 2 as per the CLP classification criteria.
Long term toxicity to aquatic invertebrate:
The study need not to be conducted as the solubility of test material in water is highly insoluble . Hence, indicating aquatic toxicity unlikely to occure.
Toxicity to aquatic algae and cyanobacteria:
The short-term toxicity of the 1,4-Bis(ethenyl)benzene; p-Divinylbenzene (CAS no.105-06-6 ) to Green algae is predicted using EPI Suite ECOSAR version 1.10. On the basis of effects observed in a static freshwater system during a 96 hr exposure, the effect concentration (EC50) for the substance is estimated to be 2.580 mg/L. Based on this value, it can be concluded that the test chemical can be considered as toxic to Green Alage at environmentally relevant concentrations and can be considered as classified in aquatic chronic category 2 as per the CLP classification criteria.
Toxicity to microorganism:
The study need not to be conducted as the solubility of test material in water is highly insoluble . Hence, indicating aquatic toxicity unlikely to occure.
