Additional information

Five studies were done on the analog substance linear alkylbenzene sulfonic acid sodium salt. The study with the lowest NOEC value was chosen as the key value. Fertilized eggs of Salmo gairdneri were exposed to concentrations of 0.03, 0.23, 0.35, 0.63, 0.95 and 1.9 mg/L (mean measured), for 72 days.The responses recorded included the survival of eggs, time to eyed egg stage, time to hatch, survival and final weight of sac-fry (eleutheroembryos), time and extent of swim-up (external feeding). The lowest NOEC value found was 0.23 mg/L based on survival of eggs exposed from eyed stage, survival of eggs exposed from fertilization, survival of sac fry, and overall survival from fertilization to swim-up. The data are for C11.6 linear alkylbenzene sulfonic acid sodium salt.
