Acute toxicity and Bioconcentration of n-dodecylbenzenesulfonate (C12LAS) to Kuruma prawn, Penaeus japonicas were evaluated. LC50 value for 45-day larvae was determined to be 4.2mg/l at 96h. This value was in the range of LC (EC) 50 values reported for other aquatic organisms, indicating that the sensitivity of the prawn was the same as those of fresh water fish like goldfish and red killifish.<BR>The bioconcentration factors of C12LAS for adult prawn were n.d.-4 and 4-17 in the muscle and internal organs, respectively, showing that the bioconcentration was relatively higher in the internal organs.However, comparison of these values with the reported no observed effect level (intake) of mammals suggests that the food hygienic risk of C12LAS in the prawn is quite low.
