Is area source air pollution dangerous than line source air pollution?
Answers
AREA SOURCES
Area sources include small pollution sources like dry cleaners, gas stations, and auto body paint shops. Area sources are defined as sources that emit less than 10 tons per year of a criteria or hazardous air pollutant or less than 25 tons per year of a combination of pollutants. The category also includes commercial buildings (heating and cooling units; surface coatings), residential buildings (fire places; surface coatings), fuel combustion in non-road machinery, boats, railroads, and even the family lawnmower or barbecue grill. Waste disposal in the form of open burning, landfills and wastewater treatment are significant area sources.
Though emissions from individual area sources are relatively small, collectively their emissions can be of concern - particularly where large numbers of sources are located in heavily populated areas. Area sources are responsible for over 50% of particulate matter emissions and more than point or mobile sources for volatile organic compound (VOC) emissions, which contribute significantly to the formation of ground-level ozone
n air pollution line source is an idealized geometric emitter, which can be represented by an
emission source consisting simply of a straight line, which may be of finite or infinite length.The
utility of this model is the ability to serve as a proxy for roadway, railway or aircraft air
pollution sources. Since widespread use of this type of model began in the USA in the early
1970s, world-wide application is presently being used by transportation engineers and urban
planners for the purpose of highway corridor alignments, highway design and analysis of aircraft
takeoff patterns.
Result is line source pollution is more dangerous
