Atmospheric Pollution by blocking some of the ultraviolet rays of the sun, can promote the development of vitamin D deficiency.
Blood levels of vitamin D were measured in two areas of Delhi, India: one with high levels of air pollution and the other with significantly less pollution.
Average vitamin D concentration was 54% lower in the former than in the latter. 46% of children in heavily polluted area had subnormal blood levels of vitamin D, in 12% the deficiency was severe enough to cause rickets.
