Additional information

Acute Fish Toxicity:

Water accommodated fractions of hydrocarbons, C10, aromatics, >1% naphthalene, produced a 96-hour LL50 value between 2 and 5 mg/L with rainbow trout, Oncorhynchus mykiss.

Chronic Fish Toxicity:

The hydrocarbons, C10, aromatics, >1% naphthalene, estimated freshwater fish 28-day NOELR (No Observed Effect Loading Rate) value is 0.487 mg/l based on growth.

Acute Invertebrate Toxicity:

Water accommodated fractions of hydrocarbons, C10, aromatics, >1% naphthalene, produced a 48-hour LL50 value between 3 and 10 mg/L with Daphnia magna.

Chronic Invertebrate Toxicity:

The hydrocarbons, C10, aromatics, >1% naphthalene, estimated freshwater invertebrate 21-day NOELR (No Observed Effect Loading Rate) value is 0.851 mg/l based on reproduction.

Algal Toxicity:

Water accomodated fractions of hydrocarbons, C10, aromatics, >1% naphthalene, produced a freshwater 72-hr EL50 value for Pseudokirchneriella subcapitata (formerly Selenastrum capricornutum) of 1.0 to 3.0 mg/l based on both growth rate and biomass. The 72-hr NOELR (No Observed Effect Loading Rate) value for Pseudokirchneriella subcapitata is approximately 1.0 mg/l based on both growth rate and biomass.

Microorganisms Toxicity:

The hydrocarbons, C10, aromatics, >1% naphthalene, estimated protozoan, Tetrahymena pyriformis, 48-hr EL50 value for this substance is 1.892 mg/L based on growth inhibition.
