The estimated 96 hour LC50 for aquatic invertebrates was calculated to range from 7.02 to 69.43 mg/L
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
mg. l-1in fresh water.
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
