Vitamin B12 and folate deficiencies are a lack of these two B complex vitamins that the body needs for several important functions. They are required to make normal red blood cells (RBCs) , repair tissues and cells, synthesize DNA (the genetic material in cells). B12 is also important for normal nerve cell function.12 and folate (also known as folic acid or vitamin B9) are nutrients that cannot be produced in the body and must be supplied by the diet. The body stores 3 to 6 years worth of B12 and about a 3 months' supply of folate in the liver.
They always occur in the summer during our monsoon period (late June through late August). Most wind storms create some blowing dust (sometimes quite severe), but it is usually localized and there is no clear boundary where the dust ends.
Technically, the driest region of the Plains â southeastern Colorado, southwest Kansas and the panhandles of Oklahoma and Texas â became known as the Dust Bowl, and many dust storms started there. But the entire region, and eventually the entire country, was affected. The Dust Bowl got its name after Black Sunday, April 14, 1935. More and more dust storms had been blowing up in the years leading up to that day. In 1932, 14 dust storms were recorded on the Plains. In 1933, there were 38 storms. By 1934, it was estimated that 100 million acres of farmland had lost all or most of the topsoil to the winds.
