The EC50 for the toxicity of Other Petroleum gases category members to aquatic algae and cyanobacteria ranged from7.71 - 16.5 mg/l
No experimental data were available on the toxic effects of category members on aquatic algae and cyanobacteria. 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 substances which were representative of the carbon numbers of the members of the category (methane, ethane, propane, butane, isobutane and propane) The EC50 for toxicity to aquatic algae is estimated to range from 7.71 to 16.5 mg.l-1in fresh water.
