Additional information

This study determined the toxicity of the analog substance linear alkylbenzene sulfonic acid sodium salt to aquatic algae. Selenastrum capricornutum was exposed to the test substance for 96 -hrs. During this time, the growth rate of the algae was measured. The 96 -hr NOEC was 0.5 mg/l. The 96 -hr LOEC was 1 mg/L. The 96 -hr EC50 was 29.0 mg/L based on growth rate.
