The 76 pages that link to Air pollution, each with the reason it gives.

• Urban sprawlRelated: Greater reliance on driving can raise vehicle emissions in sprawling regions.

• Internal combustion engineRelated: Engine exhaust releases pollutants including nitrogen oxides, carbon monoxide, and particulate matter.

• Particulate matterNarrower topic: Particulate matter is one major class of air pollutant.

• ExternalityBroader topic: Emissions impose health and environmental costs on people outside the transactions that produce them.

• LichenRelated: Many lichens absorb substances directly from the air and respond to pollutants.

• Sulfur dioxideNarrower topic: SO₂ is a major gaseous air pollutant from fuel combustion and industrial activity.

• Congestion pricingRelated: Reducing traffic can lower vehicle emissions, though the outcome depends on traffic patterns and policy design.

• Fossil fuelRelated: Fossil-fuel combustion emits particulates, nitrogen oxides, sulfur dioxide, and other pollutants.

• Natural gasRelated: Gas combustion emits fewer particles and sulfur pollutants than coal, but still produces nitrogen oxides.

• Atmospheric chemistryNarrower topic: Atmospheric chemistry explains how emissions become harmful pollutants and how they disperse or disappear.

• MeteorologyRelated: Weather controls how pollutants disperse, accumulate, and transform.

• Polycyclic aromatic hydrocarbonRelated: PAHs attached to airborne particles are one component of pollution from combustion.

• Environmental healthBroader topic: Air pollution control reduces exposures linked to respiratory and cardiovascular disease.

• Lung cancerRelated: Long-term exposure to polluted air contributes to lung cancer risk.

• Temperature inversionRelated: A low inversion can prevent polluted surface air from dispersing upward.

• Pigouvian taxRelated: Emissions taxes can price pollution harms that otherwise fall on exposed communities.

• Aviation emissionsNarrower topic: Aircraft emissions also affect local air quality around airports and along flight paths.

• Catalytic converterNarrower topic: Converters reduce several major pollutants emitted by road vehicles.

• AcetaldehydeRelated: Acetaldehyde can enter outdoor and indoor air from combustion and industrial sources.

• AtmosphereRelated: Atmospheric transport spreads pollutants across cities and regions.

• Soil contaminationRelated: Airborne pollutants can settle onto soil and become a contamination source.

• Industrial pollutionNarrower topic: Factory combustion and process emissions add gases and particles to the atmosphere.

• Oil refineryRelated: Combustion, flaring, and process releases make refinery emissions a local air-quality concern.

• NorilskNarrower topic: Sulfur dioxide and metal emissions from Norilsk’s smelters have made pollution a persistent local concern.

• Road transportRelated: Combustion engines emit pollutants, while road traffic also produces particles from tires and brakes.

• Environmental scienceRelated: Links emissions, atmospheric chemistry, exposure, and ecological damage.

• PollutionBroader topic: Air pollution is a major pathway of exposure to harmful emissions.

• Automobile dependenceRelated: Vehicle exhaust contributes pollutants near roads and across urban areas.

• Electricity generationRelated: Combustion-based generation can emit pollutants such as sulfur dioxide and particulate matter.

• FireworksRelated: Firework smoke and fine particles can temporarily worsen local air quality.

• Transport emissionsNarrower topic: Transport exhaust and non-exhaust particles worsen pollution, especially near busy roads.

• Bicycle commutingRelated: Replacing some motor-vehicle trips with bicycle journeys can reduce traffic-related emissions.

• Source controlRelated: Controls on emissions sources can reduce pollution before it disperses.

• KabulRelated: Kabul’s basin topography and winter heating can trap and intensify polluted air.

• TroposphereRelated: Many pollutants accumulate and react in the troposphere, close to people and ecosystems.

• AnticycloneRelated: Stagnant air beneath persistent anticyclones can allow pollutants to accumulate.

• Charles David KeelingNarrower topic: Keeling’s early precision work addressed whether local contamination distorted atmospheric measurements.

• MegacityRelated: Traffic, industry, and energy use can expose large megacity populations to polluted air.

• Roasting (metallurgy)Narrower topic: Uncaptured sulfur dioxide from roasting contributes to air pollution and acid deposition.

• AcroleinNarrower topic: Acrolein is an air pollutant released by combustion and formed through atmospheric chemistry.

• Active transportationRelated: Replacing motorized trips with active travel can reduce traffic-related emissions.

• Fossil fuel power stationRelated: Combustion can emit pollutants that degrade air quality around and beyond the station.

• Vehicle emissionsNarrower topic: Vehicle emissions are one source of this broader environmental problem.

• DiwaliRelated: Fireworks can sharply worsen air quality during Diwali, especially in dense cities.

• Global dimmingNarrower topic: Dimming is one climate-related effect of some airborne pollutants, not a measure of pollution overall.

• Maleic anhydrideNarrower topic: Industrial production and combustion can release maleic anhydride into air.

• UsneaRelated: Many Usnea species decline where airborne pollutants impair their growth.

• Butyl acetateNarrower topic: Butyl acetate emissions contribute to solvent-related air pollution and may be regulated.

• HighwayRelated: Vehicle emissions near highways contribute to local pollution exposure.

• MagnitogorskRelated: Heavy industry has made pollution a persistent environmental concern for the city.
