Air pollutant impacts
• Greenhouse effect
• Ozone depletion
• smog formation
• human health
• ecosystem health
Criteria Air Pollutants
• EPA uses six "criteria pollutants" as
indicators of air quality
• EPA established for each of them a
maximum concentration above which
adverse effects on human health may occur.
Criteria air pollutants
• Nitrogen Dioxide: NO2
- brownish gas irritates the respiratory system originates from
combustion (N2 in air is oxidized); NOx sum of NO, NO2, other
oxides of N
• Ozone: ground level O3
- primary constituent of urban smog
- reaction of VOC + NOx in presence of heat +sun light
• Carbon monoxide: CO
- reduces bloods ability to carry O2
- product of incomplete combustion
• Lead: Pb
- cause learning disabilities in children , toxic to liver,
kidney, blood forming organs
- tetraethyl lead - anti knock agent in gasoline
• leaded gasoline has been phased...
