Ozone and solar UV‐B radiation: monitoring of the vitamin D synthetic capacity of sunlight in Kiev and Antarctica
Abstract:Vitamin D synthesis is a well‐known beneficial effect of solar UV‐B radiation. Theoretical calculations showed the significant effect of the stratospheric ozone layer thickness on the vitamin D synthetic capacity of sunlight. During 2003–2004 permanent monitoring of solar UV radiation, using an in vitro model of vitamin D synthesis, was carried out in Kiev (50°23′N, 30°32′E) and in the Antarctic at the Vernadsky station (65°15′S, 64°16′W). Simultaneously, ozone layer thickness in the Antarctic was measured with a Dobson spectrometer. The results obtained confirm the known dramatic seasonal effect on the vitamin D synthetic capacity of sunlight. In addition, for the first time, a significant increase in the efficiency of vitamin D synthesis was revealed at the Vernadsky station in October under low ozone conditions.
