of decomposition, although uncertainty exists in quantifying its significance. It is known that UV radiation facilitates the breakdown of pesticides and may in some cases increase toxicity of certain pesticides andor their degradation products. Regarding beneficial effects of exposure of the skin to solar UV radiation the major known is the synthesis of vitamin D with is critical in maintaining blood calcium levels and is required for strong bones and its deficiency might increase the risk of an array of diseases such as cancers, autoimmune diseases and infections. The UVI is indeed, according to the UNEP report, projected to decrease by up to 7% at northern high latitudes because of the anticipated increases in cloud cover and reductions in surface reflectivity due to ice-melt while anticipated decreases in aerosols would result in increases in the UVI, particularly in densely populated areas. Outside the Polar regions, future changes in UV-B irradiance will likely be dominated by changes in factors other than ozone and by the end of the 21st century, the effect of the recovery of ozone on UV-B irradiance will be very small, leading to decreases in UVI of between 0 and 5%. Those gases that are still increasing in the atmosphere, such as halon-101 and HCFCs, will begin to decrease in the coming decades if compliance with the Protocol continues. However, it is only after mid-century that the effective abundance of ODS is expected to fall to values that were present before the Antarctic ozone hole was first observed in the early 1980s. The primary concern of the ‘ozone hole’ has been its impact on the quantity of UV-B radiation reaching Earth’s surface. As discussed earlier in this entry, stratospheric ozone plays a fundamental role in protecting surface lifeforms from exposure to harmful levels of UV-B radiation. This ‘good ozone’ typically absorbs percent of incoming UV-B radiation. We see that since 1979 through to the early 1990s, stratospheric ozone concentrations in the South Hemisphere fell to the concerning ‘ozone hole’ level of 100 DU. For several decades since the 1990s, concentrations have continued to approximate around 100 DU. Over the last few years since , however, ozone concentrations have started to slowly recover. Shown in the chart is the level of natural emissions , and total emissions which is the sum of natural and man-made emissions. Here we see a clear growth-peak-reduction trend in ozone-depleting emissions, with a rapid rise in emissions increasing more than three-fold from 1960 through to the late 1980s, followed by a similarly fast reduction in the decades which followed. By , emissions had returned to 1960 levels. This was largely the result of international regulatory agreements and concerted action to phase-out the production and consumption of these substances . Individual ozone-depleting substances are not equal in their impact on depletion. Some gases, per tonne, have a significantly higher potential for ozone depletion than others. In our section on Data
