Abstract:

The ozone depletion is created by CFCs pollutants from human activities. And this causes more UV B radiation which is harmful to marine species. According to relative research and informaiton, this paper discusses the formation of “ozone hole” and the biochemical effect of UV B on marine phytoplankton, including the tolerance and resistance of marine species to UV B, the effect of UV B on biochemical environment of marine phytoplankton cells.
