| Popis: | 1. Acute toxicity of ozone exposure to Japanese charr ( Salvelinus leucomaenis ) was studied histopathologically and hematologically on gill tissue and red blood cells (RBC) under different ozone conentrations (0–0.7 ppm). 2. Exposure of ozone above 0.7 ppm led to characteristic symptoms and all died of choking in 30 min. 3. Many swollen RBC were seen under the scanning electron microscope. 4. RBC congestion was serious in the gill where degeneration of lamellar epithelium was observed. However, injury to chloride cells was not clear. |
