Effects Of Air Pollution In Humans
Air pollution can adversely affect human health. Certain segments of population, like the elderly people, infants and children, are likely to be more sensitive to air pollution. |
Further, certain health concerns like asthma and other respiratory disorders and/or cardiovascular diseases may get aggravated in a person already suffering from them, if they are exposed to pollutants present in the air.There can be both long term and short term effects. The short term effects include, but are not limited to, irritation to the eyes, nose and throat; inflammation of the throat; rashes on the skin; and upper respiratory infections like bronchitis and pneumonia. It can also aggravate or worsen respiratory problems like asthma and emphysema in people suffering from them. Other common symptoms include headaches and nausea. An example of people suffering from the effects of air pollution in the short term is the Smog Disaster in London in 1952. Approximately 4,000 people died in few days due to over-exposure to high concentration of pollutants in the atmosphere.
Long term health effects lung cancer; chronic headache; heart diseases like hypertension; chronic stress and chronic respiratory diseases. In certain cases, it might also cause damage to vital organs like brain, liver, kidneys and the nerves. It can also cause anemia and adverse pregnancy outcomes, including miscarriage, stillbirth, low birth weight, and early infant mortality. The long term effects are more pronounced in the infants, children and the elderly. Persistent exposure to the pollutants affects the lungs of the infants and children adversely. It might also aggravate or even complicate certain medical conditions in the elderly.
The statistics pertaining to effects of air pollution on human health, in USA, is quite alarming. According to a survey conducted by the National Resources Defense Council (NRDC), approximately 64,000 people in the US may be dying prematurely each year from cardiopulmonary causes linked to air pollution.
Hence, it is imperative to prevent air pollution or at least, reduce it.
