Dust
Dust fine pulverized powder of dry earth or refuses found all through the atmosphere except perhaps on mountains top and out at sea. An atmospheres free of dusts are far healthier than which is not. Nature and industry produce dust of various kinds against which people cannot wholly protect themselves. In some instance, dust may be disastrously harmful to human being.
Microscopic particles of pollen dust borne by wind come in contact with the mucous membranes of eye and respiratory tracts and produces symptom of allergy such as seasonal hay fever, hive and other disorder. Industrial dust produced by grinding of metal and in the manufacture of wood product flour, sugar, textile, leather and feather also affects human being.
DT stands for delirium tremens.
Duodenum, first portion of small intestine, leading from stomach, it contain the opening of the pancreatic and common bile duct.
Most dust contains some carbon and other organic matter. Many people sensitive to dusts and has skin reaction when dust come in contact with skin. Other dust, when inhaled irritates windpipe and bronchial tube. Coal dust may get into lungs causing pigmentation and may stimulate production and may stimulates production of fibrous tissue, inorganic dust contains free silica incites silicosis, a special form of change in lungs. In silicosis silica act produce nodules throughout lungs which can detect by x-rays. Lungs damaged in this way are prone to secondary infection, including tuberculosis.
Asbestosis is a special form of lung disorder in which the magnesium silicate contained in asbestos produces fibrous changes that are different from those caused by pure silica, however, asbestosis and silicosis are much alike, both being form of the lung disorder pneumoconiosis.
To inhibit inhalation of dust, various form of exhaust system, air conditioning and improve ventilation has been develop. Helmets and breathing device worn by miners and worker employed in operations producing excessive dust have also been helpful.
Organic dust, like carbon, differ from inorganic dust like carbon differ from inorganic dust in that they do not cause change in the lungs such as are produced by the action of silica. Organic dust particle do not penetrate lung tissue but instead are absorbed into tissue of body.
Drought area is great dust producer, but immediate health hazard, aside from the relationship between dust storm and secondary pneumonia, are not serious. More harmful is mental and economic hardship suffered by people living in dust bowl region.
