| Abstract: |
| The acute toxicity of four halogen disinfectants to sea cucumber(Apostichopus japonicus) was determined in still water at water temperature of 18.5～20℃. The 24 h LC50, 48 h LC50 and safe concentration of trichloroisocyanuric acid(TCCA) were 33.22, 25.32 and 4.41 mg/L respectively. The 24 h LC50, 48 h LC50 and safe concentration of dibromo dimethyl hydantoin(DBDMH) were 371.17, 339.65 and 85.32 mg/L respectively. The 24 h LC50, 48 h LC50 and safe concentration of povidone-iodine(PVP-I) were 3.14, 1.45 and 0.09 mg/L respectively. The 24 h LC50, 48 h LC50 and safe concentration of quaternary ammonium salt-iodine(QASI) were 4.24, 2.02 and 0.14 mg/L respectively. The results indicated that the toxicity sequence of the four disinfectants to Apostichopus japonicus juveniles in a descent order ranged as PVP-I>QASI>TCCA>DBDMH. |
