The 63 pages that link to Particulate matter, each with the reason it gives.

• CombustionRelated: Many combustion processes release soot and other airborne particles.

• Air pollutionBroader topic: These airborne particles are a major pollutant class, especially when small enough to enter deep into lungs.

• Acid rainCompared with: Particles can share emission sources with acid precursors but are a separate class of pollutant.

• AerosolNarrower topic: Aerosols are the airborne portion of particulate matter.

• Indoor air qualityBroader topic: Indoor particles arise from cooking, combustion, dust, and outdoor air entering buildings.

• Sulfur dioxideRelated: Atmospheric conversion of SO₂ produces sulfate particles, a component of fine particulate pollution.

• BiodieselRelated: Biodiesel often reduces some particulate emissions relative to petroleum diesel, though outcomes depend on engine and fuel.

• CoalRelated: Coal smoke can contain fine particles linked to respiratory and cardiovascular harm.

• Dust stormRelated: Airborne dust contributes to particulate pollution that people inhale.

• Nitrogen oxidesRelated: Nitrogen oxides can form nitrate particles, contributing to fine-particle pollution.

• Temperature inversionRelated: Particles accumulate beneath persistent inversions when ventilation is weak.

• Tobacco smokingRelated: Fine particles in tobacco smoke penetrate deep into the respiratory tract.

• Aviation emissionsRelated: Aircraft exhaust particles contribute to atmospheric aerosol and can affect health near airports.

• Nitrogen dioxideCompared with: NO₂ is a gas, whereas nitrate-containing pollution formed from it can become particulate matter.

• Coal-fired power stationRelated: Escaped soot and ash can worsen air pollution and harm human health.

• Two-stroke engineRelated: Oil combustion and incomplete fuel burning can contribute particles to two-stroke exhaust.

• Black carbonNarrower topic: Black carbon is a particle component associated with the health risks of combustion-derived particulate matter.

• Industrial pollutionRelated: Combustion and material handling release particles that can travel far from facilities.

• Flue-gas desulfurizationRelated: Scrubbers can also capture some particles, though particulate control may require separate equipment.

• Photochemical smogRelated: Particles can accompany photochemical smog, but they are not the defining chemical product.

• PollutionBroader topic: Fine particles are a major air-pollution exposure linked to respiratory and cardiovascular harm.

• PyrotechnicsRelated: Fireworks and other pyrotechnic events can release particles that temporarily degrade air quality.

• Secondary organic aerosolNarrower topic: Secondary organic aerosol contributes to atmospheric particulate matter measured in air-quality monitoring.

• Tropospheric ozoneCompared with: It is another major air pollutant, but consists of particles rather than a reactive gas.

• Air quality indexBroader topic: Fine and coarse particles are commonly tracked as separate index pollutants.

• Electrostatic precipitatorNarrower topic: Removing particulate matter is the device's central purpose.

• Indoor air pollutionRelated: Combustion, cooking, and dust release particles that can remain airborne indoors.

• Transport emissionsRelated: Engines, brakes, tires, and road dust generate particles even when vehicles emit little exhaust.

• Ethanol fuelRelated: Ethanol blends can alter vehicle exhaust pollutants, with effects varying by engine and conditions.

• IncenseRelated: Incense smoke contains particles that can affect exposure indoors.

• Secondhand smokeRelated: Many harmful constituents of secondhand smoke travel as airborne particles.

• StrawRelated: Smoke from straw burning contains particulate matter that can harm health.

• Wildfire smokeRelated: Fine particulate matter is a major component of wildfire smoke and a key health hazard.

• IncinerationRelated: Combustion produces particles that require capture before exhaust leaves the stack.

• Indo-Gangetic PlainNarrower topic: Fine particles in the region’s haze harm health and reduce visibility.

• QuarryingRelated: Drilling, blasting, crushing, and haulage can release airborne dust from quarries.

• Air pollution controlRelated: Particle size and composition determine which collection methods can capture it.

• Biomass burningRelated: Fine particles in biomass smoke can penetrate deep into the lungs.

• Diesel generatorBroader topic: Diesel exhaust can contain fine particles associated with respiratory and cardiovascular harm.

• Fossil fuel power stationRelated: Particles from fuel burning can harm health unless emissions are effectively controlled.

• GasificationRelated: Ash and char carried from a gasifier can damage equipment and pollute exhaust if not captured.

• Tobacco smokeNarrower topic: The visible aerosol fraction of tobacco smoke consists of suspended particles and droplets.

• Vehicle emissionsBroader topic: Vehicle exhaust can contain fine soot and other airborne particles.

• DiwaliBroader topic: Fine particles from fireworks contribute to post-Diwali pollution episodes.

• SmogRelated: Particles contribute to smog's haze and health effects, whether emitted directly or formed in air.

• Atmospheric aerosolBroader topic: Air-quality limits commonly regulate aerosol particles as particulate matter.

• Air purifierNarrower topic: Particle size determines how pollutants move indoors and which filtration mechanisms can capture them.

• CigaretteRelated: Cigarette smoke carries particles that can deposit throughout the respiratory tract.

• FireplaceRelated: Wood combustion releases fine particles that can harm respiratory and cardiovascular health.

• FirewoodRelated: Wood smoke contains fine particles that can enter the lungs.
