Air Pollution Flashcards
Primary pollutants
(which means they are emitted directly into the atmosphere by a particular source)
VOC
Carbon monoxide
NOX
Sulfurdioxide
particulate matter
Lead
Secondary pollutants
NOX produce nitric acid
Sulfur dioxide produce sulfuric acid
Ozone
Particulate pollutants
Dust
Lead and other metals particles
Fly Ash
Suspended particulate matter
Smoke from domestic,
industrial and vehicular soot
Reduces sunlight and visibility,
Increases corrosion,
Pneumoconiosis, asthma, cancer,
and other lung diseases.
Particles less than 10μm float and move freely
FLY ASH
Part of smoke released from
chimneys of factories and
power plants
Indoor air pollution
Poor ventilation
Paints, carpets, furniture, etc. in rooms may give out volatile organic compounds
(VOCs)
Use of disinfectants may release hazardous gases
Industrial air pollution remedies
increase chimney height
use cleaner feuls like LNG
Install devices which ireduce the release ofpollutants (filters , scrubbers)
shifting polluting industries away from the cities
Devices
Filters
Electrostatic precipetators
Intertial collectors -
Scrubbers - are wet collectors
Acid rain
Industries often emit large amounts of Nitrogen and Sulphur gases into the atmosphere
that react with water vapors in the atmosphere, they often change into more aggressive
gases, namely nitric acid and Sulphuric acid.
Respiratory Disorders:
The emission of various gases, such as carbon monoxide, sulphur oxides, VOCs, etc, as well
as particulate matter, often results in various respiratory disorders such as bronchitis, asthma,
Ozone Layer Depletion:
The ozone layer is a gaseous blanket that helps in supporting and sustaining life on Earth
by protecting us from various hazardous radiations such as UV rays.
Globalwarming solutions
Reduce, Reuse, Recycle
Plant a tree
Drive less and smart
use less heat air conditioning
