Overview
The physical
effects of pollution are manifold. Pollution, in its many forms, can
have immediate and long-terms effects on your body's systems and your
overall health.
Exposure to pollution also affects your quality of life,
and can increase your risk of certain chronic diseases. The physical
effects of pollution on your health depend on the type of pollution to
which you're most frequently exposed, including air, water or noise
pollution.
Air Pollution
According to the
Lawrence Berkeley National Laboratory (LBL), a laboratory conducting
scientific research for the U.S. Department of Energy, the degree to
which you're harmed by air pollution depends on your level of exposure
to injurious chemicals. The longer your exposure to such chemicals, and
the higher the concentration of the chemicals to which you're exposed,
the higher your level of exposure and likelihood of suffering an air
pollution-related illness. Short-term physical health effects of air
pollution include the following: eye, nose and throat irritation, upper
respiratory infections--including bronchitis and pneumonia--headaches,
nausea, allergic reactions and exacerbation of medical conditions, such
as emphysema and asthma. Long-term physical health effects of air
pollution may include chronic respiratory disease, lung cancer and heart
disease. Long-term exposure to air pollution may even cause damage to
your brain, nerves, liver or kidneys, states LBL.
Water Pollution
The Water
Pollution Guide, a U.K. website dedicated to minimizing your risk of
exposure to water pollution, states that water pollution is more likely
to produce long-term health effects than immediate health effects. The
Guide suggests that chemicals--such as heavy metals--from industrial
processes are especially harmful sources of water pollution. Heavy
metals that accumulate in lakes and rivers harm fish and other marine
life and the humans who eat them. The physical health effects of heavy
metals include blunted development, birth defects and possibly cancer.
Other physical health effects associated with ingesting water
contaminated with industrial waste include immune suppression,
reproductive failure and acute poisoning. Other problematic pollutants
that can be found in water include the following: microbial pollutants
from sewage, excessive organic matter and nutrients and sulfate
particles from acid rain.
Noise Pollution
According to a
Jun. 5, 2007 article by Rick Weiss in the Washington Post, over 100
million Americans are exposed to noise levels over 55 decibels on a
regular basis--a noise level federal agencies have suggested is a
reasonable background intensity. Excessive exposure to noise pollution
may provoke feelings of annoyance, disrupt your sleep and cause
cognitive impairment and boost your blood pressure. According to the
National Association of Noise Control Officials, noise is a stressor
that affects your health, and it may exacerbate your stress-related
medical conditions, including hypertension, ulcers, coronary disease,
colitis and headaches. Excessive exposure to noise pollution may even
result in your child being born with birth defects or a low birth
weight, suggests NANCO. Short-term physical health effects of noise
pollution include the following: elevated heart rate, breathing rate and
blood pressure, along with inhibition of your digestive processes.
