Additional information
Discussion concerns tests with the whole substance and also the understanding of the properties of blocks and constituents. The constituent properties are needed for the risk characterisation conducted using the hydrocarbon block method and for the PBT assessment.
Measured data are available for whole substance and these are used for the purposes of hazard classification. Predictions for individual hydrocarbon blocks is used for the purposes of risk characterisation. Prediction for long-term effects data is difficult since it depends markedly on the model used. PNECs are therefore based on HC5 values calculated using PETROTOX
The following experimental ecotoxicological results are available:
Acute toxicity:
-(96h) LL50 for freshwater fish rainbow trout (Oncorhynchus mykiss): >100 mg/l (WAF, nominal, based on mortality) [OECD 203; test mat. C4-C10 branched and linear hydrocarbons (light) – Naphtha]
-(48 h) EL50 for Daphnia magna (freshwater): > 18 < 32 mg/l (WAF, nominal, based on immobilisation) [OECD 202; test mat. C4-C10 branched and linear hydrocarbons (light) – Naphtha]
-(72 h) EL50 for Pseudokirchneriella subcapitata: > 100 mg/l (WAF, nominal, based on: growth rate) [OECD 201; test mat. C4-C10 branched and linear hydrocarbons (light) – Naphtha]
-(48 h) LC50 for Daphnia magna (freshwater): 2 mg/l (calculation) [OECD 202; read-across with 'Alkylate naphtha'; supporting study]
-(48 h) EL50 for Daphnia magna (freshwater): 10 mg/l (calculation) [OECD 202; read-across with 'Naphtha (petroleum), isomerization'; supporting study]
Chronic toxicity:
-(33 d) NOEL rate for fathead minnoes (pimephales promelas): 100 mg/l (WAF, nominal, based on:fish length and dry weight) [OECD 210; test mat. C4-C10 branched and linear hydrocarbons (light) – Naphtha]
-(21 d) NOEL rate for Daphnia magna (freshwater): 22 mg/l (WAF, nominal, based on immobilisation) [OECD 211; test mat. 'C4-C10 branched and linear hydrocarbons (light) – Naphtha]
Conclusion on classification
Considering all available data of the acute and chronic toxicity tests on aquatic organisms, environmental fate issues and taking into account the provisions laid down in Regulation (EC) No. 1272/2008, the substance does not need to be classified with respect to acute and long-term toxicity towards environmental organisms.
