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.
The Dust Bowl, also known as the Dirty Thirties, was a period of severe dust storms that greatly damaged the ecology and agriculture of the American and Canadian prairies during the 1930s; severe drought and a failure to apply dryland farming methods to prevent wind erosion (the Aeolian processes) caused the phenomenon.
