Additional information

The members of this category are gases and will predominantly partition to the atmosphere. This will limit their aquatic toxicity. Due to the difficulty associated with conducting aquatic toxicity tests, experimental data was not available for the members of this category. In the absence of measured data, estimated data was 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 (butane, isobutane, butene, isobutene). The toxicity of the substances was calculated to range from 7.7mg/l to 27.9 mg/l for the different aquatic taxanomic groups.
