Volatile Organic Compounds
(VOC) Incomplete combustion, evaporation of solvents or gas, emission from plants Mixture of compounds, some carcinogenic, help form ozone
Suspended Particulate Matter
(PM) Soot, Smoke, Metals, and carbon combustion, dust salts and dirt. Complex mixture of solids particles and aerosols; reduces lung function and affects respiration and cardio
Carbon Monoxide
(CO) Incomplete combustion Invisible, odorless, tasteless gas; poisonous by binding to hemoglobin to block oxygen delivery
Nitrogen Oxides
(NOx) From nitrogen gas due to high combustion temperatures when burning fuels or wood Reddish-brown gas and lung irritant; aggravates respiratory disease, acid rain, aids ozone
Sulfur Dioxide
(SO2) Coal, Poisonous gas; impairs breathing, acid rain, aids ozone
Lead
(Pb) Battery Manufacture; lead smelters; combustion of leaded fuels Toxic at low concentrations, accumulates in body and can lead to brain damage
Air Toxics
(–) Combustion, industrial processes, bulding materials, solvents Toxic chemicals, many of which are known carcinogens
Radon
(Rn) Rocks and soil; natural breakdown of radium or uranium Invisible and odorless radioactive gas can accumulate inside homes; second leading cause of lung cancer
Ozone
(O3) Photochemical reaction between VOC’s and NOx Toxic to animals and plants and reactive in lungs, oxidizes surfaces and rubber tires
Peroxyacetyl Nitrates
(PAN) Photochemical reactions between VOC’s and NOx Damages plants and forests; irritates mucous membranes of eyes and lunges
Sulfuric Acid
(H2SO4) Oxidation of (SO2) by OH radicals Produces acid deposition damages lakes, soils, and artifacts
Nitric Acid
(HNO3) Oxidation of (SO2) by OH radicals Produces acid deposition damages lakes, soils, and artifacts
(PM) Soot, Smoke, Metals, and carbon combustion, dust salts and dirt. Complex mixture of solids particles and aerosols; reduces lung function and affects respiration and cardio
