Exposure of CHSE-214 cells to hydrogen peroxide (H₂O₂) in freshwater: (a) preexposure; (b) 30 min at 1 mM (34 ppm) H₂O₂; (c) 60 min at 1 mM (34 ppm) H₂O₂; (d) 240 min at 50 mM (1700 ppm) H₂O₂; (e) damaged cells at the beginning of the 100 mM (3400 ppm) H₂O₂ bath (magnification: 100X); a change in focal plane in Figure 1(e) also suggests that cells might be detached from the bottom surface of the flask.
