The aquatic toxicity assessment of TD53, a new algicidal compound, was performed by acute toxicity using a phytoplankton, a crustacean, and a young fish.Three aquatic organisms employed in this experiment: Skeletonema Costatum as a phytoplankton that is basic producer of marine ecosystem, and Daphnia magna as a crustacean that was used for the testing of chemicals according to OECD guidelines, and Paralichthys olivaceus as a young fish that is secondary consumer.
As a result of the exposure experiments, EC50 value of TD53 to Skeletonema Costatum showed 1.21 μM when exposed for 96 hrs, and the EC50 value in Daphnia magna was 0.62 μM for 48 hrs exposure, and the LC50 value of Paralichthys olivaceus was 2.48 μM for 72 hrs. On the other hand, solutol used as a dispersion material to elevate solubility of TD53 showed no considerable toxicity in the range of concentration used in the experiment of TD53.From the results above, Daphnia magna was most sensitive to TD53 among the three organisms than other aquatic organisms. Based on that results, NOEC (No Observed Effect Concentration) for TD53 was calculated to be 0.25 μM, and PNEC (Predicted No Effect Concentration) by employing factor value of 100 was concluded to be 6.2 nM.
