Air pollution can be termed as the change in physical, chemical and biological aspects of air due to addition of unwanted contents known as “pollutants”. Air pollution is one of the major forms of pollution brought to this world by urbanization.
United State’s Most Polluted Cities:
America has seen a great increase in air pollution in terms of ozone depleting pollutants, short term pollutants and year round pollutants. Some major American cities which contribute to air pollution are: San Diego, Los Angeles, Cincinnati, Sacramento, Bakersfield, Houston, Phoenix, Salt Lake City, Philadelphia, Pittsburgh and a few more.
Worldwide CO2 Emissions:
By far China has the worst statistics for CO2 emissions by releasing 6,200 million tons of carbon dioxide every year. But United States is not very far behind and it comes second by releasing 5,800 million tons of carbon dioxide per year. U.K. comes third and releases 490 million tons of CO2 annually while Niue has the worldwide least rate of CO2 emission.
Diseases caused by Air Pollution:
In California children suffered from brain conditions like autism because they grew up in locality full of toxic air pollutants. In North Carolina severe cases of Alzheimer’s was witness due to high rate of air pollution. 2.8 million of the adult American population suffer from asthma a breathing disorder caused by air pollution. Chronic bronchitis, heart problems and pancreatic problems are also caused on a large level by air pollution.
Health Hazards of Air Pollution:
Air pollution causes the following health hazards in humans: respiration problems, heart problems, reproductive disorders, premature death, lung redness, chronic infection, cancer, coughing and wheezing, etc.
Quality of Air:
America’s three cities make it to the top ten cities of the world with worst air quality. Pittsburgh, Pennsylvania, Los Angeles and Bakersfield are considered to be the most polluted cities in all of United States. California is the most polluted state of United States.
Measuring Air Pollution:
Air pollution can be measured by existence of pollutant/particulate matter in air. This pollutant PM10 is very small in size and has a diameter less than 10 microns, which is one fifth times smaller than diameter of human hair.
Air Pollution Damages your Skin:
The worst cities in United States for your skin are L.A., Fresno, Phoenix, Memphis, San Diego, Sacramento, Las Vegas, Tulsa and Forth Worth.
Bad Indoor Air:
It is believed that 2 million people die because they suffocate from an illness which is enhanced by the bad quality of indoor air. 60% of all residential and working places are not safe to inhabit and are sick due to indoor allergens like dusts, mites, etc. AC's and Air filters are very cause of bad indoor air.
Public Health in Danger:
The number of adults as well as children with asthma is increasing day by day in America. Bad Air bills are sponsored by leaders like Ted Poe, John Carter, Marsha Blackburn and Shelley Moore to reduce the risks of air pollution to common public.
Not just urbanization is blamed for air pollution. The increased emission of air pollutants by households like Co2 emission or CFC emissions are also causing air pollution.
Measuring Air Quality:
If we are able to follow a metrics to measure the quality of air we are breathing then we can make the necessary changes in our environment and in our day to day activities so that we can keep the air clean and live in a better world.
