this will provide quick discussion on atmospheric chemistry and some other details on atmosphere including layers of the atmosphere and environmental problems in the atmosphere
The atmosphere is the gaseous layer surrounding the Earth. It is composed primarily of nitrogen (78%) and oxygen (21%), along with smaller amounts of other gases like carbon dioxide and water vapor. The atmosphere protects life on Earth by regulating temperature, blocking harmful radiation, and enabling processes like photosynthesis. Air pollution from human activities like burning fossil fuels threatens ecosystems and human health through effects like acid rain and respiratory problems. The greenhouse effect retains some of the Sun's heat in the lower atmosphere, maintaining temperatures suitable for life; however, increased greenhouse gases are causing global warming and its consequences.
The document summarizes key components and characteristics of Earth's atmosphere. It describes the major gases that make up the atmosphere, including nitrogen, oxygen, carbon dioxide, water vapor, aerosols, and ozone. It also explains the vertical layers of the atmosphere, including the troposphere, stratosphere, mesosphere, and thermosphere. Additionally, it discusses atmospheric temperature variations and how Earth's climate is influenced by factors like sunlight, the greenhouse effect, and atmospheric circulation patterns.

Atmospheric stability
Earth’s atmosphere is a thin blanket of gases and tiny particles — together called air.
Atmosphere is the air surrounding the earth.
The Earth’s atmosphere is a mixture of gases and water vapour, and also of some amount of aerosols (dust, smoke, condensation products of vapor)
It contains life-giving gases like Oxygen for humans and animals and carbon dioxide for plants.
It envelops the earth all round and is held in place by the gravity of the earth.
It helps in stopping the ultraviolet rays harmful to the life and maintains the suitable temperature necessary for life.
The document summarizes the structure and composition of Earth's atmosphere. It is divided into multiple layers - troposphere, stratosphere, mesosphere, thermosphere and exosphere - based on how temperature varies with altitude. Each layer has distinct characteristics and contains different gases. The troposphere contains around 80% of atmospheric mass and is where weather occurs. The stratosphere contains the ozone layer which absorbs harmful UV radiation. The main atmospheric gases are nitrogen (78%) and oxygen (21%), along with trace amounts of argon, carbon dioxide, water vapor and other gases. Dust and water particles are also present and influence cloud formation and precipitation.

Air pollution has existed for centuries, exacerbated by the industrial revolution and rise of automobiles. Some key events in air pollution history include Hippocrates mentioning it in 400 BC, London's Smog of 1952 killing over 4,000, and the Bhopal gas tragedy of 1984 in India. The atmosphere is composed mainly of nitrogen and oxygen, and is divided into layers including the troposphere containing most air pollution. Primary pollutants such as carbon monoxides, nitrogen oxides, and particulates are emitted directly, while secondary pollutants form through atmospheric reactions. Unchecked air pollution can have severe health and environmental impacts.
The atmosphere is the gaseous layer surrounding the Earth. It is composed primarily of nitrogen (78%) and oxygen (21%), along with smaller amounts of other gases like carbon dioxide and water vapor. The atmosphere regulates the Earth's temperature and protects the surface from harmful radiation and meteorites. It also provides essential gases for life, such as oxygen for respiration and carbon dioxide for photosynthesis. However, human activities like burning fossil fuels have increased greenhouse gases and depleted the ozone layer, contributing to issues like global warming, acid rain, and increased UV radiation at the surface.
The document discusses environmental chemistry topics including air, water, and soil pollution. It then provides details about the composition and layers of Earth's atmosphere. The main layers discussed are the troposphere, which contains around 75% of the atmosphere's mass, and the stratosphere above it. The stratosphere contains the ozone layer, which absorbs harmful ultraviolet radiation from the Sun and protects life on Earth. The formation and depletion of ozone in the stratosphere is also explained.

2. o Major regions of Atmosphere
o Atmosphere as a Resource
o Types and Sources of Air Pollution
• Major Classes of Air Pollutants
• Sources of Outdoor Air Pollutants
• Urban Air Pollution
o Chemical and photochemical reactions in
atmosphere
o Photochemical smog: its constituents and
photochemistry
o Effects of Air Pollution
2
3. Major Regions of Atmosphere: On the basis of temperature:
What is atmosphere? Discuss the different zones of atmosphere.
3
4. Troposphere (Tropo = turning or changing)
• Bottom layer 🡪 from Earth’s surface to about 12
kilometers altitude (0 to 7.5 miles)
• Where we live & weather happens, clouds form, air
moves a lot here 🡪it’s turbulent and well-mixed
• gets colder with increasing altitude…to about -550 C (-
670 F) at the top (tropopause) (Temperature range 150C to
-560C)
Think about how it gets colder on a mountain?
4
5. Troposphere
o most of atmosphere’s
mass is here 🡪 the
densest layer because
gravitational pull is
stronger here
o Jet stream is in
upper troposphere &
lower stratosphere…
o Airplanes do not fly
higher than about 11
km …~7 miles up
5
6. Stratosphere: Strato = layer or “spreading
out” ...air does not move a lot here
o above the troposphere
o You can see where it begins
because large cumulonimbus
storm clouds reach into and
stop at the lower stratosphere
o Extends to ~50 km (31 mi)
o Way less air pressure
here…less mass above, less
density and less gravitational
force
6
7. Stratosphere
o OZONE is formed in this
layer….O3 absorbs most UV
radiation from sun
o temperatures increase with
altitude in the stratosphere
because of ozone.
As ozone molecules absorb UV they
get energized, move faster and
produce heat
Is ozone
good or
bad?
7
8. Mesosphere
o ~50-90 km (31 – 50 mi)
o meso = middle
o 99.9% of mass lies below the
mesosphere
o Not enough oxygen to
breathe but % is still the
same (What % is that?)
o Most meteoroids burn up
here…. the air is very thin,
but still dense enough to
slow down meteoroids due
because of friction
8
9. Mesosphere
o There is not an ozone layer to cause heating
so, temperatures decrease with altitude in
the mesophere
o Coldest layer! down to -1480 F (-1000C ) at
the mesopause…
What is a
“pause”?
What is a “pause”?
9
10. Thermosphere
o Above the mesosphere to ~690 km
(430 miles)….with no real upper limit
🡪 space!
o least dense of all layers …. few
molecules are far apart & moving
fast because of radiation absorption
10
11. Thermosphere
o temps can reach 2,0000
C (3,6000 F) … but would
feel very cold…too few
hot molecules to transfer
heat
o Temperatures can vary greatly
here because of solar activity
o Thermo = heat
o Sometimes divided into
two layers : ionosphere
and exosphere
11
12. Ionosphere
o lower part of thermosphere
o solar radiation very strong here & is absorbed by
the few oxygen & nitrogen molecules resulting in
electrically charged gas particles (ions) that cause
heat (O2
+, O+
, NO+)
o AM radio waves bounce off these ions and back
to earth
o Aurora Borealis(Northern Lights) ….glowing ions
12
13. Exosphere
o ” Outer thermosphere & outermost layer
of the atmosphere
o Exo = “outer(To infinity & beyond! )
o Satellites orbit here
o Atoms & molecules
escape into space here
o TV & cell phone signals
travel to satellites here
and are bounced back
13
14. Atmosphere as a Resource
o Atmospheric Composition
• Nitrogen 78.08%
• Oxygen 20.95%
• Argon 0.93%
• Carbon dioxide 0.04%
o Ecosystem services
• Blocks UV radiation
• Moderates the climate
• Redistributes water in the
hydrologic cycle

15. Air Pollution
Chemicals added to the atmosphere by natural events or
human activities in high enough concentrations to be
harmful.
or
It is the direct or indirect changes in one/more components
of biosphere that are harmful for living entities.

16. Types and Sources of Air Pollution
Two categories:
oNatural
• Forest fire by lightening
• Soil erosion
• Volcanic eruption
• Decomposition of organic matter and natural
radioactivity
o From human activity
• U V radiation due to Ozone layer depletion
• Nuclear fall out radioactive materials
• From industries
• From burning of fossil fuel

17. Two categories
o Primary Air Pollutant (Contributes ~ 90%)
• Harmful substance that is emitted
directly into the atmosphere
o Secondary Air Pollutant
• Harmful substance formed in the
atmosphere when a primary air pollutant
reacts with substances normally found in
the atmosphere or with other air
pollutants

21. Major Classes of Air Pollutants
o Carbon Oxides
o Hydrocarbons
o Nitrogen Oxides
o Sulfur Oxides
o Particulate Material
o Ozone
21
22. Carbon Oxides and Hydrocarbons
o Carbon Oxides
• Gases carbon monoxide (CO) and carbon
dioxide (CO2)
• Greenhouse gases
o Hydrocarbons
• Diverse group of organic compounds that
contain only hydrogen and carbon (ex: CH4-
methane)
• Some are related to photochemical smog and
greenhouse gases
22
23. Nitrogen and Sulfur Oxides
o Nitrogen Oxides
• Gases produced by the chemical interactions
between atmospheric nitrogen and oxygen at
high temperature
• Problems
• Greenhouse gases
• Cause difficulty breathing
o Sulfur Oxides
• Gases produced by the chemical interactions
between sulfur and oxygen
• Causes acid precipitation
23
24. Particulate Material
o Thousands of different solid or liquid
particles suspended in air
• Includes: soil particles, soot, lead, zinc,
asbestos, sea salt, and sulfuric acid droplets
o Dangerous for two reasons
• May contain materials with toxic or
carcinogenic effects
• Extremely small particles can become lodged in
lungs
24
25. Ozone
o Tropospheric Ozone
• Man- made pollutant in the lower atmosphere
• Secondary air pollutant
• Component of photochemical smog
o Stratospheric Ozone
• Essential component that screens out UV
radiation in the upper atmosphere
• Man- made pollutants (ex: CFCs) can destroy it
O2 plays an important role in Troposphere and O3 in Stratosphere
25
26. Sources of Outdoor Air Pollution
o Two main sources
• Transportation
• Industry
o Intentional forest
fires is also high
26
27. Urban Air Pollution
o Photochemical Smog (ex: Los Angeles below)
• Brownish-orange haze formed by chemical reactions
involving sunlight, nitrogen oxide, and hydrocarbons

28. Two very important Factors on
Atmospheric chemistry
Important Gaseous Atmospheric Chemical Species
28
29. Gaseous atmospheric Chemical Species
o Sunlight of U V region and Hydroxyl radicals (OH.)
are important as it provides a way to pump high level
of energy into a single gas molecule to start a series
of Chemical reactions.
o Hydroxyl free radicals are the most reactive
intermediate and currency of day time atmospheric
phenomena where as NO3 radicals are important
intermediate in night time atmospheric chemistry.
o Both solid and liquid particles in atmospheric aerosols
and clouds serve as sources and sinks for gas-phase
species, as sites for surface reactions.
