Additional information

The environmental effects of the hydrocarbons, C9-C12, aliphatics, 2 -25% aromatics has been defined by a series of studies on fish, Daphnia, and algae.  Results of the key studies showed that this substance would exhibit LL50 or EL50 values (based on loading rate of water accommodated fractions) of 10-30 mg/L (fish), 10-22 mg/L (Daphnia), and 4.1 and 4.6 -10 mg/L (for both growth and biomass of algae).  All of these studies were conducted using Water Accommodated Fraction (WAF) methodology because of the complex composition and limited water solubility of constituents in hydrocarbons, C9-C12, aliphatics, 2 -25% aromatics.

Chronic toxicity to fish was estimated to be 0.13 mg/l (NOELR based on growth). Studies on invertebrates and algae found NOELR of 0.28 mg/l (based on reproduction) and 0.16 / 0.22 mg/l (based on algal biomass) respectively.

The environmental effects of the hydrocarbons, C10-C13, aliphatics, 2 -25% aromatics has been defined by a series of studies on fish, Daphnia, and algae.  Results of the key studies showed that this substance would exhibit LL50 or EL50 values (based on loading rate of water accommodated fractions) of 10-100 mg/L (fish), 100-220 mg/L (Daphnia), and 10 -100 mg/L (for both growth and biomass of algae).  All of these studies were conducted using Water Accommodated Fraction (WAF) methodology because of the complex composition and limited water solubility of constituents in hydrocarbons, C10 -13, aliphatics, 2 -25% aromatics.

 

Chronic toxicity to fish was estimated to be 0.091 mg/l (NOELR based on growth). Studies on algae found a 72 -hour NOEL of 3 mg/l (based on growth and biomass).

The environmental effects of the hydrocarbons, C11-C14, aliphatics, 2 -25% aromatics has been defined by a study on fish. Chronic toxicity to fish was estimated to be 0.079 mg/l (NOELR based on growth).

The estimated protozoan, Tetrahymena pyriformis 48-hr EL50 value forHydrocarbons, C9-C12, n-alkanes, isoalkanes, cyclics, aromatics (2-25%)is 43.98 mg/L, based on growth inhibition.

The estimated protozoan, Tetrahymena pyriformis 48-hr EL50 value for Hydrocarbons, C11-C14, n-alkanes, isoalkanes, cyclics, aromatics (2-25%) is 185.1 mg/L, based on growth inhibition.

The substances belonging to the category "Hydrocarbons, C9 -C14, aliphatics (2-25% aromatics)" have shown to be biodegradable. Therefore, they are not toxic to microorganisms.

Conclusion on classification

For purposes of environmental classification, hydrocarbons, C9-C12, aliphatics, 2 -25% aromatics fall within a 1 to 10 mg/L range for acute aquatic toxicity. These substances are considered to be readily biodegradable.

 

For purposes of environmental classification, hydrocarbons, C10-C13, aliphatics, 2 -25% aromatics fall within a 10 to 100 mg/L range for acute aquatic toxicity. These substances are considered to be readily biodegradable.

For purposes of environmental classification, hydrocarbons, C11 -C14, aliphatics, 2 -25% aromatics fall within a 10 to 100 mg/L range for acute aquatic toxicity. These substances are considered to be readily biodegradable.
