Description of key information

The estimated 96 hour LC50 for aquatic invertebrates was calculated to range from 7.02 to 69.43 mg/L

Key value for chemical safety assessment

Additional information

No experimental data were available on the short-term toxic effects of category members on aquatic invertebrates. Due to the difficulty associated with aquatic toxicity testing with gases, QSAR calculations are considered suitable to estimate the effect concentration. ECOSAR Program v1.00 in EPI Suite v4.00 was used, which is acceptable with restrictions. QSAR calculations were conducted for category members (methane, ethane, butane, isobutane and propane). The LC50 (96 hours) for invertebrates is estimated to range from14.22 to 69.43 mg. l-1in fresh water.

However, due to the volatility of the petroleum gases, the calculated effect concentrations are not relevant in practice, but are used as an indication of potential toxicity
