In order to perform an acute toxicity assessment of a new algicide, thiazolidinedione derivative (TD53) with enhanced solubility and lower toxicity to marine ecosystem, representative 3 organisms: plant plankton (Skeletonema costatum), animal plankton (Daphnia magna), fish (Paralichthys olivaceus) related in the food chain of marine ecosystem according to OECD standard methods were employed in the exposure experiment. The exposure assessment showed that EC<SUB>50</SUB> of S. costatum in 96-hour, EC<SUB>50</SUB> of D. magna in 48-hour and LC<SUB>50</SUB> of P. olivaceus in 72-hour for TD53 were 1.53 μM, 0.61 μM and 2.14 μM respectively. NOEC (No Observed Effect Concentration) and PNEC (Predicted No Effect Concentration) were calculated to be 0.25 μM and 6.10 nM, respectively from EC<SUB>50</SUB> of most sensitive strain, D. magna. Comparing with the results of toxicity
assessment previously performed by using Ulva pertusa Kjellman accepted as an ISO standard method, the values of PNEC showed 3.7 times lower toxicity in case of this study employing 3 organisms, indicating that if the organisms which are more representative and sensitive in marine ecosystem are further investigated, more accurately and validly predicted toxicity of TD53 could be applied in field.
