Air pollution occurs when harmful or excessive quantities of substances including gases (such as carbon dioxide, carbon monoxide, sulfur dioxide, nitrous oxides, methane and chlorofluorocarbons), particulates (both organic and inorganic), and biological molecules are introduced into Earth's atmosphere.
In atmospheric chemistry, is a generic term for the nitrogen oxides that are most relevant for air pollution, namely nitric oxide (NO) and nitrogen dioxide.

Clean Air Act (United States)

Clean Air ActClean Air Act Amendments of 1990Clean Air Act of 1970
In the United States, despite the passage of the Clean Air Act in 1970, in 2002 at least 146 million Americans were living in non-attainment areas—regions in which the concentration of certain air pollutants exceeded federal standards.
The Clean Air Act of 1963 (42 U.S.C. § 7401) is a United States federal law designed to control air pollution on a national level.

Nitrogen dioxide

When developing the AQHI, Health Canada's original analysis of health effects included five major air pollutants: particulates, ozone, and nitrogen dioxide (NO2), as well as sulfur dioxide (SO 2 ), and carbon monoxide (CO).
At higher temperatures it is a reddish-brown gas that has a characteristic sharp, biting odor and is a prominent air pollutant.

Asthma

The health effects caused by air pollution may include difficulty in breathing, wheezing, coughing, asthma and worsening of existing respiratory and cardiac conditions.
Environmental factors include exposure to air pollution and allergens.

Environmental impact of the coal industry

Environmental effects of coalCoal burningcoal pollution
The environmental impact of the coal industry includes issues such as land use, waste management, water and air pollution, caused by the coal mining, processing and the use of its products.

Smog

Photochemical smog, as found for example in Los Angeles, is a type of air pollution derived from vehicular emission from internal combustion engines and industrial fumes.

Dust

Lead paint can degenerate into dust and be inhaled.
On Earth, it generally consists of particles in the atmosphere that come from various sources such as soil, dust lifted by wind (an aeolian process), volcanic eruptions, and pollution.

Lung cancer

lungbronchogenic carcinomalungs
Sufferers have severe dyspnea (shortness of breath) and are at an increased risk regarding several different types of lung cancer. In 2012, air pollution caused premature deaths on average of 1 year in Europe, and was a significant risk factor for a number of pollution-related diseases, including respiratory infections, heart disease, COPD, stroke and lung cancer.
These cases are often caused by a combination of genetic factors and exposure to radon gas, asbestos, second-hand smoke, or other forms of air pollution.

Houseplant

house planthouseplantsindoor plant
Pets produce dander, people produce dust from minute skin flakes and decomposed hair, dust mites in bedding, carpeting and furniture produce enzymes and micrometre-sized fecal droppings, inhabitants emit methane, mold forms on walls and generates mycotoxins and spores, air conditioning systems can incubate Legionnaires' disease and mold, and houseplants, soil and surrounding gardens can produce pollen, dust, and mold.
A houseplant is a plant that is grown indoors in places such as residences and offices, namely for decorative purposes, but studies have also shown them to have positive psychological effects and as well as help with indoor air purification, since some species, and the soil-dwelling microbes associated with them, reduce indoor air pollution by absorbing volatile organic compounds including benzene, formaldehyde, and trichloroethylene.

List of pollution-related diseases

pollution-related diseasesdisease-causing pollution
In 2012, air pollution caused premature deaths on average of 1 year in Europe, and was a significant risk factor for a number of pollution-related diseases, including respiratory infections, heart disease, COPD, stroke and lung cancer.
There are many different types of pollution-related diseases, including those caused by air pollution, contaminated soil, water pollution and lacking water, sanitation and hygiene (WASH).Air pollution can be reduced.

Tropospheric ozone

Ground level ozone is a prominent example of secondary pollutants.
Ozone is also measured in air quality environmental monitoring networks.

Chronic obstructive pulmonary disease

In 2012, air pollution caused premature deaths on average of 1 year in Europe, and was a significant risk factor for a number of pollution-related diseases, including respiratory infections, heart disease, COPD, stroke and lung cancer. Chronic obstructive pulmonary disease (COPD) includes diseases such as chronic bronchitis and emphysema.
Tobacco smoking is the most common cause of COPD, with factors such as air pollution and genetics playing a smaller role.

Toxicity

Indoor air pollution and poor urban air quality are listed as two of the world's worst toxic pollution problems in the 2008 Blacksmith Institute World's Worst Polluted Places report.

Great Smog of London

A study conducted in 1960–1961 in the wake of the Great Smog of 1952 compared 293 London residents with 477 residents of Gloucester, Peterborough, and Norwich, three towns with low reported death rates from chronic bronchitis.
The Great Smog of London, or Great Smog of 1952, was a severe air-pollution event that affected the British capital of London in early December 1952.

Diesel exhaust

Diesel exhaust (DE) is a major contributor to combustion-derived particulate matter air pollution.
However, the lean-burning nature of diesel engines and the high temperatures and pressures of the combustion process result in significant production of gaseous nitrogen oxides (NO x ), an air pollutant that constitutes a unique challenge with regard to their reduction.

Criteria air pollutants

Criteria air contaminantscriteria pollutantscriteria pollutant
These dangerous pollutants are known as the criteria pollutants, and include ozone, particulate matter, sulfur dioxide, nitrogen dioxide, carbon monoxide, and lead.
Criteria air Pollutants (CAP), or criteria pollutants, are a set of air pollutants that cause smog, acid rain, and other health hazards.

Risk factors during pregnancy include certain infections, such as rubella, toxins including valproic acid, alcohol, cocaine, pesticides, lead, and air pollution, fetal growth restriction, and autoimmune diseases.

The problem is even more acute in the developing world.
For example, with regards to health risks, they commonly have: low levels of access to safe drinking water, sanitation and hygiene; energy poverty; high levels of pollution (e.g. air pollution, indoor air pollution, water pollution); high proportion of people with tropical and infectious diseases (neglected tropical diseases); high number of road traffic accidents; and generally poor infrastructure.

A recent study in Europe has found that exposure to ultrafine particles can increase blood pressure in children.
Regulations do not exist for this size class of ambient air pollution particles, which are far smaller than the regulated PM 10 and PM 2.5 particle classes and are believed to have several more aggressive health implications than those classes of larger particulates.
