storms occur speaks to a tremendous number of people detrimentally affected by the natural occurrence. II. IMPACT OF DUST STORMS Australia is one area in which dust storms impact
human health, being that a considerable amount of the continent is comprised of the aforementioned land composition. The disastrous combination of severe and widespread drought "can dramatically increase the
likelihood of major dust storms" (NSW Department of Health, 2003), especially during summer. At issue is the manner by which dust storms whip up particles into the atmosphere, inherently
creating poor air quality and visibility; these undesirable side effects are what irritate peoples eyes, lungs and overall respiratory system, particularly exacerbating problems for those with pre-existing health concerns as
asthma and emphysema (NSW Department of Health, 2003). Dust particles cannot be well tolerated by the human respiratory system, manifesting this inability through such ailments as chronic breathing problems, lung
obstruction and even heart disease. Their composition is both fine and coarse; however, some particles are ultra fine as to be easily respirable, one of the most invasive of
all forms. Coarse particles make the shortest passage through the human body by virtue of their larger size, typically getting only as far as the mouth, nose or throat.
Finer particles by contrast are able to reach deeper into the respiratory system, more easily infiltrating deeper into the lungs and other "sensitive regions" (NSW Department of Health, 2003).
For the most part, dust storms are comprised of coarse particles as opposed to finer ones, allowing most people to bypass the more serious consequences of this natural event; it
is when a condition already exists - such as diabetes, heart disease and respiratory problems - that even the coarse dust storms can be troublesome to others. Infants, children,
