Part 2: ENVIRONMENTAL AND OCCUPATIONAL HAZARDS /16
Some people are exposed to dangerous materials when at work or being in the environment. You are given 4 materials that might cause health problems in humans when exposed to it too much.
You are asked to read each below and make a few notes. You might consider the following: A.. Cause of the disease. B.. Symptoms of the disease. C.. Cures/ treatments/ or preventions for this disease. D.. List 3 jobs where a person would be exposed to this hazardous substance. You might need to use the internet to answer this question.
1. ASBESTOS:
"Asbestos causes a variety of lung problems. The first one is restrictive lung disease. This is where there is widespread lung scarring from many years of being exposed to asbestos. Later, it was recognized that such persons are at higher risks for lung cancer, a risk that is greatly increased if the person also smokes cigarettes.
Pleural disease also affects asbestos workers. This takes the form of calcified scars known as plaques. Occasionally, fluid accumulates in the pleural cavity. Calcification is seen on an X-ray. When plaques form on the pleura membranes around the lungs, breathing is difficult because the membranes cannot stretch as easily.
The obvious way to deal with this is to limit your exposure to asbestos. This may involve quitting the job, wearing protective measures such as face masks and protective clothing. There are herbs to help clear out the lungs. Quitting smoking will allow the cilia in the throat area to grow back and help to remove the particulate matter from the lungs.
2. SILICOSIS:
Silicon is one of the most common elements in the earth's crust. Quartz, sand and sandstones, flint, granite, and other hard stones have high amounts of silica in them. Silicosis result from repeated exposure to free crystals deposited in the lungs. Persons at risk for silicosis include sandblasters, hard rock tunnellers, quarry workers, stone cutters, and foundry workers.
The method of lung scarring by silica is better understood than the scarring of asbestos. Silica is a potent killer of lung macrophages. Macrophages are part of the immune system that normally surround and destroy foreign particles. Macrophages cannot work properly when silica is around. When macrophages ingest silica particles, they are killed off. When they die, the macrophages give off inflammatory chemicals that cause scarring in the nearby tissue.
There are no clear symptoms of silicosis. The first indication usually is an abnormal chest X-ray, with scattered pinpoint punctures throughout the lung. Fortunately, most patients never proceed beyond this stage. In a few people, the pinpoint punctures enlarge to spread to cover large areas of destruction. Patients become breathless and the respiratory system may fail.
Quitting the job, changing jobs, and wearing protective measures would help prevent continuous injury.
3. CHEMICAL IRRITANTS:
A large number of gases used in industrial processes irritate the respiratory system. They include ammonia, hydrogen chloride, chlorine, sulfur dioxide, and nitrogen dioxide. The soluble gases, such as chlorine and ammonia, cause upper respiratory irritation. Symptoms may include chest pain and a cough. The non-soluble gases, such as nitrogen dioxide, causes extra fluid to build up in the alveoli. This makes it harder for oxygen to move from the lungs to the bloodstream. Treatments may include: better ventilation for the gases at work, supplemental oxygen, or steroids.
4. HYPERSENSITIVITY LUNG DISEASES:
These are diseases caused by an immune reaction where certain organic substances are inhaled into the lungs. In farmer's lung, particles of fungus growing in mouldy hay are shaken into the air when the hay is stirred up. Then the fungus is inhaled into the lungs where they are attacked by the body's immune defenses. Fever, chills, and breathlessness follow. Similar diseases may be caused by fungi from animal danders (skin cells) or feathers. Only a small percentage of those exposed develop the disease" (Kiester, 1989).
