Effect of hexachlorobenzene (HCB) on photosynthetic oxygen evolution and respiration of Chlorella pyrenoidosa

Effect of hexachlorobenzene (HCB) on photosynthetic oxygen evolution and respiration of Chlorella pyrenoidosa

In experiments with Chlorella pyrenoidosa it was shown that an exposure of these cells to HCB at a dose level of 0.1, 1.0, and 5.0 ppm caused an inhibition of photosynthetic oxygen evolution of 33.3, 42, and 51%, respectively. Respiration, however, was inhibited only slightly, if at all.
