Cross-sectional studies often show associations between diabetes and air pollution, although somewhat inconsistently. A Canadian study found that exposure to nitrogen dioxide NO2 air pollution was associated with higher levels of diabetes in women, but not men. This study did not include other air pollutants, but instead considered nitrogen dioxide to be a marker of traffic-related air pollution.
Air quality[ change change source ] Pollution can be gas or liquid or solid. It can also be classified chemically, such as: Pollution can also be classified by what makes it.
Many pollutants go into the air from natural sources. These pollutants include dust, sea saltvolcanic ashes and gasessmoke from forest fires, pollenand many other materials.
Primary pollutants are pollutants that are put directly into the air by humans or natural sources. Examples of primary pollutants are exhaust fumes gas from carssoot from smoke, dust storms and ash from volcanic eruptions as seen in the picture on the left.
Ozone and smog are secondary pollutants. Ozone is a gas that stops harmful ultraviolet rays from the sun. When it is near the ground, though, it can poison people and other organisms. Most air pollution made by humans today is because of transportation. The gases inside car exhaust, like nitrogen oxidemake smog and acid rain.
Farmlands and forests sometimes burn in wildfires producing soot a black powder composed mainly of carbon, produced when coal, grasses, wood etc. Soot can affect people and other life.
People start many of those fires. Industrial air pollution[ change change source ] Many industrial power plants burn fossil fuels to get their energy. However, burning fossil fuels can make a lot of oxides chemical compounds that have oxygen and other elements inside. Some industries also make chemicals that make poisonous fumes smoke.
Indoor air pollution[ change change source ] Air pollution is not only on the outside. Homes, schools, and buildings can also have air pollution. Sometimes the air inside a building is even worse than the air outside.
Compounds inside carpets, paints, building materials and furniture also pollute the air, especially when they are new.
In buildings where the windows are tightly shut to stop air leaks, the air inside can be polluted more than the air outside. When fossil fuels are burned, they let out oxides into the air. When these oxides mix with water in the atmosphere, they make acid, which fall as precipitation. Acid rain can also damage buildings made of limestone and concrete.
Ozone hole[ change change source ] A global concern is the hole in the ozone layer in the stratosphere. The Earth's ozone layer protects life from the Sun's harmful ultraviolet rays, but in the s, scientists found out that some chemicals let out into the atmosphere makes the ozone turn into oxygen.
This lets more ultraviolet rays reach the Earth. This does not often happen, but being exposed to air pollution every day can make people have many health problems. Children, elderly old people, and people with allergies especially, can have a lot of problems because of air pollution.
Studies from the University of Birmingham showed that deaths because of pneumonia and air pollution from motor vehicles like cars are related.What is air pollution?

Around 99 percent of all farm animals are raised in one of the 20, factory farms in the U.S. Concentrating millions of animals onto factory farms has a number of negative effects.
Crowded by. A new study has shown how household products such as shampoo are sources of the same air pollution as traffic fumes. However, rather than being bad news, this is becoming apparent because of the. Discover the risks of air pollution in Thailand.
I use realtime reports & reliable studies to show the cleanest & dirtiest areas to live in. The term "heat island" describes built up areas that are hotter than nearby rural areas. The annual mean air temperature of a city with 1 million people or more can be –°F (1–3°C) warmer than its surroundings.
In the evening, the difference can be as high as 22°F (12°C). Heat islands. THE AIR (PREVENTION AND CONTROL OF POLLUTION)1 ACT, (Act No. 14 of ) [29 March, ] An Act to provide for the prevention, control and abatement of air pollution.
