Additional information
Quantitative environmental exposure assessment and risk characterisation was conducted with the PETRORISK tool that is designed for environmental risk assessment of petroleum hydrocarbons. The model calculations are based on physicochemical and ecotoxicological properties of individual hydrocarbon structures, so that PEC and PNEC and the risk characterisation by RCR are derived for representative structures that are used to simulate the UVCB substance. The sum of all individual RCR values indicates the overall risk for the substance as the environmental effects of the individual components are considered additive.
Risk assessment in the PETRORISK tool is based on PNEC values for water, wastewater, soil, and sediment. PNECair are not included. The PNEC values in the PETRORISK tool are HC5 values, which is the hazardous concentration that affects 5% of organisms. The HC5 values are derived from a database that includes effects data for aquatic and marine covering both pelagic and benthic species. The PNECsoil and PNECsediment are estimated using the Equilibrium Partitioning Method.
Conclusion on classification
The following data was used in classification and labelling of renewable hydrocarbons of wood origin (naphtha type fraction)
Aquatic acute toxicity:
48-h EL50 (immobilisation) D. magna, 7.6 mg/l with 95% CI of mg/l (OECD 202; WoE), read-across data from fossil fuel:
blended gasoline sample W94/813 (CAS 86290-81-5)
72-h EL50 (growth rate) Desmodesmus subspicatus, > 100 mg/l (OECD 201, GLP, key study)
96-h LL50 (mortality) Oncorhynchus mykiss, 10 mg/l with 95% CI of 4.5-23 mg/l (OECD 203, WoE), read-across data from fossil fuel: Naphtha (petroleum), isomerization
Conclusion:No acute toxicity as the lowest toxicity value is > 1 mg/l.
Aquatic chronic toxicity:
No adequate long-term study results are available. Aquatic toxicity is evaluated based on the short-term study results presented above. Based on the available short-term study results, the lowest toxicity is < 10 mg/l. and the substance is classified to Aquatic Chronic Category 2.
Biodegradation:
Based on the read-across study (OECD 301F, GLP) conducted on similar substance (High Naphtenic, Heavy, Straight-Run Naphtha) the the target UVCB substance is regarded as readily biodegradable. The screening studies conducted with the test substance produced unexpectedly low biodegradation (0 and 8,05 deg-%) indicating possible problems with testing or sampling and packing of the substance, and therefore these tests were used only as supportive information.The probability of biodegradation estimated (BIOWIN) for the ten most abundant individual structures of the substance indicate ready biodegradability. Based on the composition this substance is hydrolytically stable.
Conclusion: Substance is considered as readily biodegradable.
Bioaccumulation:
Testing of the BCF was considered technically unfeasible for this UVCB substance. As determination of BCF experimentally was not feasible, the bioaccumulation potential of the substance was assessed based on test results from the octanol-water partitioning coefficient study (log Kow of 4.7). Based on the experimental data, the substance might contain substances having potential for bioaccumulation. For complex mixtures (e.g. UVCBs) a single value of Kow will not be definitive. The log Kow values were also estimated with the PETRORISK tool that was used for the environmental risk assessment. The estimation is based on log Kow values of individual compound structures, which are included in the CONCAWE Library. The overall range for the estimated log Kow values was from 1.83 to 5.2. The log Kow values of the representative individual structures that form the major part of the substance based on mass fraction (sum 0.7) were in the range 2.7 -4.3.
Bioconcentration factors and bioaccumulation factors were also estimated with the BCFBAF v3.01 model. The estimated log BCF value for the ten most abundant individual structures of the substance ranged from 2.02 to 3.08 (BCF = 105 to 1202 L/kg).
Conclusion: The range of log Kow values indicated that there might be constituents present in the substance having potential for bioaccumulation (log Kow values > 4). As the estimated BCF values are also > 500 L/kg substance is considered to contain hydrocarbons which have bioaccumulation potential. However, the substance as whole cannot be considered as bioaccumulative (see also section 8).
