Breathing dust is bad for anybody’s health. The IARC, the institution of the World Health Organization that deals only with cancer, has already defined particles with a diameter equal to or less than 2.5 m as sure carcinogens. This is the reason why the concentration of dust is monitored especially in cities and limits must be observed that mayors, the highest health authorities of the municipality, however, not alwaysuphold or do not uphold at all.
ASTMA, ALLERGY and COUGH are the most immediate reactions of the human body to the inhalation and breathing of dust, reactions that are more serious the greater the concentration of dust and in dependence on factors such as their shape, their size and their chemical composition.
GRANULOMATOSIS, SARCOIDOSISare reactions of the lungs to coarse dusts. An inflammatory granulation tissue envelops the particles trying to isolate them from healthy tissue. Electron microscopy identifies and analyzes them within the affected tissue.
PULMONARY CANCERin all its various forms. With the chronicization of an inflammatory reaction such as that which occurs with the formation of a granulation tissue, a cancer can be triggered and subsequently increased. The difference between the various forms of lung cancer is due to various factors including the size of the powders, their concentration, their shape (fundamental for asbestos cancers), their chemical composition, the rate of intake and its duration.
ASBESTOSIS. Fibrosis induced by asbestos fibers from pleural tissue up to the alveoli.
BERILLYOSIS. Occupational disease with granulomatosis, chronic allergic reaction to beryllium inhalation.
PNEUMOCONIOSIS. This name indicates the diseases caused by the entry of dust into the lung: talcosis for talc, asbestosis for asbestos, anthracosis for coal, silicosis for silicon, etc. Identifying the presence of dust in the tissues is essential to remove the patient from the polluting source.
Powders with a diameter smaller than 1 micron negotiate the pulmonary barrier, end up in the blood and invade the whole body including liquor and the brain.
