ENVIRONMENTAL MANAGEMENT
LECTURE 2 - AIR

Dr. Nguyen Thi Hoang Lien



NATURAL SOURCES OF AIR POLLUTION
• Volcanoes
• Fires
• Plant/Animal off gassing
• Dust storms


HUMAN CREATED AIR POLLUTION
• Major sources: transportation, electric plants
(coal, oil) and industry (steel mills, metal
smelters, oil refineries and pulp/paper mills).
• Minor sources: small engines, wood burners,
etc.


POINT SOURCES vs NON-POINT SOURCES
• Point source mean any disceminable, confined
and discrete conveyance, including but not
limited to any pipe, ditch, channel, tunnel,
conduit, well, discrete fissure, container, rolling
stock, concentrated animal feeding operation
or vessel.
• Non-point source (NPS) generally results from

land runoff, precipitation, atmospheric
deposition, etc.


NON-POINT SOURCE
•
•
-

NPS pollution can include…..
Sources for NPS:
Urban
Mining*
Forestry
Agriculture


NON-ATTAINMENT AREAS vs
ATTAINMENT AREAS
• In United States environmental law,
a nonattainment area is an area considered to
have air quality worse than the National
Ambient Air Quality Standards as defined in
the Clean Air Act Amendments of 1970 (P.L.
91-604, Sec. 109). Nonattainment areas must
have and implement a plan to meet the
standard, or risk losing some forms of federal
financial assistance. An area may be a
nonattainment area for one pollutant and an
attainment area for others.

INDOOR AIR POLLUTION SOURCES
• Combustion sources
• Building materials & furnishing
• Products
for
household
clearing
&
maintenance, personal care or hobbies
• Central heating & cooling systems &
humidification devices
• Outdoor sources such as radons, pesticides,
outdoor air pollution


HEALTH BASED CRITERIA
Health based criteria for (science based
guidelines) primary standard = protects health
secondary standard = prevents environmental
and property damage.
