Description of key information
Additional information
Short-term toxicity to fish
A water soluble fraction of Hydrocarbons, C11 -C14, n-alkanes, isoalkanes, cyclics, <2% aromatics prepared at a loading of 803,000 mg/L did not produce mortality to the fish, Oncorhynchus mykiss, during a 96-hour exposure period.
Long-term toxicity to fish
Petrotox calculations determined that for Hydrocarbons, C13 -C15, n-alkanes, isoalkanes, cyclics, <2% aromatics were not toxic to fish. Results of computer modelling to estimate chronicity in 28 -day freshwater fish study, based on growth, show that Hydrocarbons, C13 -C15, n-alkanes, isoalkanes, cyclics, <2% aromatics will not produce toxicity at or below its maximum attainable water solubility.
Short-term toxicity to aquatic invertebrates
The water accommodated fraction (WAF) of Hydrocarbons, C11-C14, n-alkanes, isoalkanes, cyclics, <2% aromatics did not produce a 50% effect (mortality) with Chaetogammarus marinus at a loading of 10,000 mg/L after a 96-hour exposure. Therefore, the 96-hour LL50 is reported as >10,000 mg/L. There was no mortality at the 10,000 mg/L loading level after 96 hours. Therefore, the 96-hour NOELR for mortality is reported as 10,000 mg/L. There was also no mortality in the control.
The water accommodated fraction (WAF) of Hydrocarbons, C11-C14, n-alkanes, isoalkanes, cyclics, <2% aromatics did not produce a 50% effect (immobility) with Daphnia magna at a loading of 1000 mg/L after a 48-hour exposure. Therefore, the 48-hour LL50 is reported as >1000 mg/L. There was no mortality at the 1000 mg/L loading level after 48 hours. Therefore, the 48-hour LL0 for mortality is reported as 1000 mg/L. There was also no mortality in the control.
Long-term toxicity to aquatic invertebrates
The aquatic toxicity of was estimated using the Petrotox computer model, which combines a partitioning model used to calculate the aqueous concentration of hydrocarbon components as a function of substance loading with the Target Lipid Model used to calculate acute and chronic toxicity of non-polar narcotic chemicals. Petrotox computes toxicity based on the summation of the aqueous-phase concentrations of hydrocarbon block(s) that represent a hydrocarbon substance and membrane-water partitioning coefficients (KMW) that describe the partitioning of the hydrocarbons between the water and organism.
The 21-d NOELR for aquatic invertebrates, Daphnia magna and Ceriodaphnia dubia, based on reproduction was found to be >100 mg/L and >1000 mg/L, respectively according to Petrotox calculations. The experimental studies could not determine LL50.
Toxicity to algae and cyanobacteria
Growth of an alga culture,Pseudokirchnerella subcapitata, as measured by biomass and growth rate, exposed to a 1000 mg/L water accommodated fraction of Hydrocarbons, C11-C14, n-alkanes, isoalkanes, cyclics, <2% aromatics was not inhibited when compared to the control after a 72-hour exposure. Therefore, the 72-hr EL50 and NOELR values for these two endpoints are reported as >1000 mg/L and 1000 mg/L, respectively.
Toxicity to microorganisms
Hydrocarbons, C13 -C15, n-alkanes, isoalkanes, cyclics, <2% aromatics were not found to be toxic for aquatic microorganisms (LC50 >100 mg/L).
