Description of key information

Additional information

The substances in the category are gases and will predominantly partition to the atmosphere, which will limit the aquatic toxicity. Due to the difficulty associated with conducting aquatic toxicity tests, experimental data were not available for the members of this category. In the absence of measured data, estimated data were calculated using the QSAR model

ECOSAR Program v1.00. in EPI Suite v4.00. Calculations were conducted using substances which were considered representative of the category members (methane, ethane, propane, butane, isobutane). The toxicity of the substances was calculated to range fom 7.71 mg/L to 147.54 mg/L for the different aquatic taxonomic groups.
