Determining the lethal concentration (LC50 96h) of phenol and 1-naftol for Acipenser persicus fingerlings

The toxic effects of the oil products Phenol and 1-Naftol on fingerlings of the Persian sturgeon were studied in 2003. We carried out five treatments with three replicates and one control for each of the chemicals using the static O.E.C.D. method in 20 liter aquariums each containing 10 fingerlings. During the experiments, the average pH was recorded as 7.2, total hardness was measured to be 194 mg/l, average water temperature was 25.1 degrees centigrade and dissolved oxygen was 7.2 mg/l. Using the Probit Analysis procedure, we found that the LC50 96h of the Phenol and 1-Naftol for fingerlings of the Persian sturgeon was 36.65 and 1.32 mg/l respectively. We determined the maximum allowable concentration of the Phenol and 1-Naftol for the fingerlings of the Persian sturgeon to be 3.66 and 0.13 mg/l respectively.
