- Salt storm
A salt storm is a low-lying cloud of airborne
salt that hovers over large areas, the result of wind sweeping oversalt flat s. Salt storms usually occur in places with large aboveground deposits of salt, such as those surrounding theGreat Salt Lake inUtah , and the salt flats surrounding theAral Sea . Salt storms in the latter of which pose a serious health hazard to surrounding areas, as the minerals blown about by these storms are highly toxic, leading to adverse health effects such as throat and lung cancer, infant mortality, and decreased life expectancy. Furthermore, birth defect rates are higher in the regions surrounding the Aral Sea. The damage is caused by breathing in the toxic chemicals in the air (many of which are the result ofrun-off from nearby farms), and by taking in the chemicals in food and water. Salt storms can also block visibility and cause chemical damage to surrounding structures.Salt storms are also a frequent phenomenon in the
