Air pollution air pollution

Is air pollution a serious problem? Its effects can range from higher disease risks to rising temperatures. It is typically separated into two categories: outdoor air pollution and indoor air pollution.

Outdoor air pollution involves exposures that take place outside of the built environment. They are particularly common in highly populate urban areas, where there may be a combination of stationary sources (e.g. industrial facilities) and mobile sources (e.g. cars and trucks) of pollution. In an even broader sense, air pollution means the presence of chemicals or compounds in the air which are usually not present and which lower the quality of the air or cause detrimental changes to the quality of life (such as the damaging of the ozone layer or causing global warming).

What is air pollution ? The Clean Air Act authorizes the U. Environmental Protection Agency. It is also one of the leading risk factors for disease burden. The leading sources of air pollution are power plants , factories, and vehicles. They constantly emit fumes and gaseous waste into the atmosphere. Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.

More than one in deaths in Britain are linked to air pollution , according to the Centre for Cities charity, which works with the government to develop urban policies. The two most widespread types of air pollution are the ozone and particle pollution (soot), but air pollution also may include serious pollutants such as carbon monoxide, lea nitrogen oxides, and sulfur dioxide, volatile organic compounds (VOCs) and toxins such as mercury, arsenic, benzene, formaldehyde, and acid gases. It creates respiratory problems and exacerbates existing conditions such as asthma and emphysema. Therefore, air pollution means the undesirable presence of impurities or the abnormal rise in the proportion of some constituents of the atmosphere.

When continually exposed to air pollution , humans become at higher risk for cardiovascular disease. The pollutants come in many forms. They may be liquid droplets, solid materials, etc and many more. Pollutants can be further subdivided into two heads, primary and secondary.

Closer look at the activities that cause air pollution include: 1. Emissions From Industrial Plants and Manufacturing Activities. With the current rate of industrialization and increased manufacturing activities, high levels of smoke, sulfur dioxide, and particulate matter are emitted into the air. This is because the air becomes dirty (contaminated or unclean).

Even 0years ago, the Romans were complaining about the bad air in their cities. Whereas primary pollutants are caused by primary sources – i. Pollution from natural occurrences is not very often. Air pollution in the United States has improved since the introduction of the Clean Air Act. However, did you know that indoor air is on average two to five times more polluted than outdoor air ? This happens because the air circulation indoors is much lower than outdoors, which allows toxins from dust particles, vapors from cooking, painting or furniture dyes to accumulate inside our houses.

Those affected by poor air quality can develop serious breathing and health problems such as asthma, chronic bronchitis, and even emphysema.
