Mean atmospheric ozone levels have increased steadily in the last 25 years, and this is likely to have decreased the amount of UVR reaching the earth's surface. Vitamin D3 formation in man depends on the UV irradiation of a precursor in the skin, and so we have used a computer, and the action spectrum for D3 production, to calculate the probable reduction in vitamin D3 formed by the human skin as a result of the increased ozone levels. We estimate that in the period from 1951 to 1972 the total vitamin D accumulation by the body might have thus been reduced by 15%.
在过去25年中，大气臭氧平均水平持续上升，这可能减少了到达地球表面的紫外线辐射量。人体内维生素D3的形成依赖于皮肤中一种前体物质的紫外线照射，因此我们利用计算机和D3生成的作用光谱，来计算由于臭氧水平上升导致人体皮肤形成的维生素D3可能减少的量。我们估计，在1951年至1972年期间，人体维生素D的总积累量可能因此减少了15%。
