Ozone Hole Consequences. These tiny plants capture the sun's energy through photosynthesis. It is estimated that a 16 % ozone depletion could result in. Abstract. Concerns about stratospheric ozone depletion have stimulated interest in the effects of UVB radiation (280–320 nm) on marine phytoplankton. The Montreal Protocol on Substances that Deplete the Ozone Layer (a protocol to the Vienna Convention for the Protection of the Ozone Layer) is an international. The Impacts of Ozone Depletion. Stratospheric ozone filters out most of the sun's potentially harmful shortwave ultraviolet (UV) radiation. If this ozone becomes. Ozone and photosynthesis?. We have less ozone each year, and the rate of depletion does not correlate with the amount we have. See the. Allen et al., 1998; Allen, D.J., Nogués, S., Baker, N.R., 1998. Ozone depletion and increased UV-B radiation: is there a real threat to photosynthesis? Ozone depletion is largely a result of. It is also important to know that O 2 is constantly being introduced into the atmosphere through photosynthesis, so the. We assessed the influence of springtime solar UV-B radiation that was naturally enhanced during several days due to ozone depletion on biomass production and. This solar energy conversion process is known as photosynthesis. with the separate problem of stratospheric ozone depletion. Ozone creation and depletion. Ozone in the lower atmosphere (troposphere) is toxic to human beings and many species of plants, causing harm without visible symptoms. The Ozone We Breathe focuses.
