| In order to estimate the effects of chlorine used in cooling systems of electric power plants on zooplankton, some experiments have been realized with the four first larval stages of the prawn (P. serratus Pennant). Chlorine injection was performed by constant adding at 16 and 20 degree C with times exposures of 5, 15 and 25 minutes. If there is no detectable variations in sensitivity of different stages, toxic effects of oxydants issued from chlorination can be observed (for both the two acclimatation temperatures) at 15 minutes exposure with a LD 50 : 32 mg/l of chlorine. |

| The growing development of thermonuclear electric plants on coastal areas drove the I.S.T.P.M. to carry out a number of impact studies. Previous works on the impact of the transit in the condensers on the phytoplankton have been published by the Pollution Biological Effects laboratory (Maggi el al., 1979 and 1980; Lassus and Maggi, 1980). Our results on the chlorophycea Dunaliella terliolecla demonstrated that thermic elevations from low temperatures stimulated its cellular development. Therefore, it seemed interesting to measure the effects of these thermic shocks on dinophyceae (or dinoflagellates), components, with diatoms, of the coastal phytoplankton, and main agents of the summer phenomena known as "red waters". |
