Air pollution

Major classes of air pollutants including anthropogenic sources and effects.

Carbon monoxide (Co) sources

-incomplete combustion of fossil fuels, esp in vehicles
-cigarette smoke

Carbon monoxide (CO) effects

Dizziness, drowsiness, headache, death (asphyxiant)

Carbon dioxide (CO₂) sources

Burning fossil fuels and wood, deforestation, clearing of land (decay and release from soil)

Carbon dioxide (CO₂) effects

Climate change

Sulfur dioxide (SO₂) sources

Burning coal, oil refineries, smelting

Sulfur dioxide (SO₂) effects

respiratory irritation and acid rain

Nitrogen oxide (NO and NO₂=NO_x) sources

Automobiles and utilities (electricity)

Nitrogen oxide (NO and NO₂=NO_x) effects

respiratory irritation, photochemical smog, acid rain

VOCs = volatile organic compounds sources

Dry cleaning solvent, gas, paint thinner, acetone, sharpies, paint

VOCs = volatile organic compounds effects

Dizziness, drowsiness, unconsciousness, respiratory irritation, photochemical smog

SPM = suspended particulate matter are…

SPM sources

Farms, roads, construction sites, industry, fire

SPM effects

respiratory irritation, aggravates asthma, lung damage

lead (Pb) sources

old chipping paint- dust, smelting materials, burning coal, leaded gasoline

lead (Pb) effects

Low cognition, blindness, short stature, hearing loss

Mercury (Hg and compounds) sources

BURNING COAL, burning garbage , smelting

Mercury (Hg and compounds) effects
