No one disputes the refreshing benefits of
clean air; but farmers know that clean air on the farm can be hard to
find. Still, many continue to put their health at risk without
taking a simple, comforting precaution, like purchasing a
Trend®
Airshield. What are the
risks?
When fine dust enters the respiratory system, the human body considers it to be foreign material which should be defended against. The main effects of dust on health are an inflammatory response (chronic irritation) or a toxic response. The delayed symptoms include headache, dizziness, nausea, breathlessness, fever, and vomiting, leading to unproductive coughing and breathing difficulties. These symptoms usually appear 3 to 4 hours after exposure, reach a peak in 7 to 8 hours and disappear after 24 hours. "Farmer's Lung" and "Organic Dust Toxic Syndrome" are examples of delayed hypersensitivity of the respiratory system to specific dust. There are three categories of health effects. First, there can be some temporary damage to the respiratory system which will disappear rapidly when the person is no longer exposed to dust. Second, there can be the occurrence of insidious damage to the respiratory system such as bronchitis or occupational asthma after long-term exposure to dust. The reaction is not as explosive as an allergic reaction, but has various symptoms such as coughing, shortness of breath, or a reduction of pulmonary capacity. However, when the workers are no longer exposed, the respiratory system may, but not always, recover entirely. Third, farm workers can develop permanent lung damage without showing any allergic reactions when they are continuously exposed to dust for long periods of time. This means that some parts of their lung tissue are permanently affected reducing respiration capacity. Unfortunately, this process is irreversible. Farmers are at an added risk.
