Ozone toxicity to bluegill (Lepomis macrochirus) was determined using standard bioassay procedures. In initial work bluegill were exposed to water containing ozone for 24 h; the LC50 was 0.06 ppm. A second experiment simulated “shock defouling” — the periodic dosing of power plant cooling water with high biocide concentrations to prevent biofouling. The LC50 for a series of six 30-min exposure periods spaced 8 h apart was 0.32 ppm. A third experiment attempting to determine the effects of sublethal concentrations resulted in the death of 9 of 15 bluegill after 4 weeks of exposure to 0.01 ppm of ozone. No controls died in any experiment. It was concluded that ozone is highly toxic to bluegill. Safe limits for long-term exposure probably lie well below 0.01 ppm. The results of this study and an examination of the literature indicate that ozone is more toxic than chlorine; however, ozone is readily removed from treated water while some chlorine compounds are not. |
