Immobilized daphnids at 48 hrs – LAB
This study determined the short-term toxicity of linear alkyl benzenes
to Daphnia magna. Daphnids were exposed to concentrations of 0,
12.5%, 25%, 50%, 75%, and 100% saturated test solution for 48 hrs. At
the end of this period, the daphnids were observed for mobility. Though
immobilized daphnids were seen at 4 test concentrations, there was no
dose-related increase in immobilization, nor was the number of
immobilized daphnids significantly increased over negative controls. The
48 -hr EC50 is >0.041 mg/l, this is greater than the water solubility
for the test substance.
