| Abstract: | Organ chlorine insecticide endosulfan (ES) is one of the persistent organic pollutants (POPs) and it may pose a serious threat to microalgae. Here, we evaluate the toxic effects of ES on three marine microalgae, including the diatom Ditylum brightwellii, dinoflagellate Prorocentrum minimum and green algae Tetraselmis suecica. The endpoints used for toxicity assessment were changes in cell counts and chlorophyll a levels. Median effective concentration (EC50) was calculated after 72 h-ES exposures and the values for D. brightwellii, P. minimum, and T. suecica were determined to be 0.0013, 0.025, and 0.045 mg L-1, respectively. These results indicate that our marine microalgae were very sensitive to the ES exposure even under environmentally realistic concentrations. Particularly, the diatom D. brightwellii was most sensitive to ES, when compared to data available on freshwater microalgae. |
