"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

2. Pollution
• Pollution is accummulation of
harmful matter in the environment;
rate of flow of which exceed capicity
of ecosystem to nutralize or disperse
them below harmful levels.
4. AIR
• Troposphere> Stratosphere >
Mesosphere> Thermosphere
• Innermost layer of atmosphere (17
km high)is troposphere with 75% of
mass of air.
• An average human need 12Kg of
fresh air daily for breathing.
5. Air pollution
• Air pollution defined as the presence
of one or more contaminants or
combinations in such quantities and
of such durations whish may be
injurious to human, animal or plant
life, or property, or which
unreasonably interferes with normal
functioning of life.
8. Pollutants
• Primary (identifiable source):-
Carbondioxide, Nitrogen Dioxide,
Sulphur Dioxide
• Secondary:- Produced in atmosphere
by reaction. Nitric acid, Carbonic
acid, Sulphuric acid

10. Global Warming
• The earth heats up (the
temperature rises)
• It happens when greenhouse
gases (carbon dioxide,
nitrous oxide, and methane)
trap heat and light from the
sun in the earth’s
atmosphere, which
increases the global
temperature.
11. Green house effect
• The greenhouse effect is when the
temperature rises because the sun’s
heat and light is trapped in the
earth’satmosphere.
• The heat and light can get through
the atmosphere, but it can’t get out.
As a result, the temperature rises.
• Sometimes the temperature can
change in a way that helps us.
12.
13. Green house effect
• Without it, the earth would be
freezing at night because the sun
would be down. We would not get
the sun’s heat.
• On the other hand, because of it
would be burning hot during the day,
especially during the summer.
14. What is global warming doing
to the environment?
• Rise in sea water level because of
melting ice on south and notrh pole
• The water covers many low land
islands, and because rising sea level
human and animal lose a source of
food, along with their habitat
• Global warming, is harming and
killing algae in the ocean which is
responsible for photosynthesis.
15. Ozone layer Depletion
• Upper stratosphere consist higher
concentration of ozone.. this region is
called ozone layer
• From earth surface this layer is
between 20-25 Km
• Ozone os O3
• It is produced by photodissociation of
oxygen in atmosphere
• Presence of certain pollutent
accelerate breakdown od ozone
16.
17. Ozone layer Depletion
• In 1985 large scale of ozone
destruction (ozone holes) came into
light by british researchers
• It was established that CFCs are
mainly responsible for depletion of
ozone
• CFCs are highly useful in aerosoles,
airconditioners, refregirators
• Chlorine is released from CFCs
because of direct UV which attac O3
molecule and destroy it
• Ozone over countries like Australia
New Zealana is depleted, South africa
18. Effects of ozone layer depletion
Ozone is responsible for absorption of
harmful UV rays comming fron sun
• Effect on human- sun burns
• Plant- affect photosynthesis
• Climate- global warming
• Effect on microorganism
19. Acid Rain
• Oxides of sulphur and nitrogen from
industrial operations and fossil fuel
combustion
• In atmosphere these gases convert
into sulfuric and nitric acid
• These acids cause acid rain
20. Acid Rain
• Rainwater turn acidic when pH fall
below 5.6
• Sulfuric acid form major component
of acid rain
• In urban area Ca, Mg and ammonium
ion help to nutralize the acidity of
rain
• In absence of rain dry deposition of
rain may occur
• A unit decrease in pH causes 10 fold
increase in acidity (H+)
21. Effect of Acid rain
• It causes deterioration of buildings
specially made of marble Eg. Taj
Mahal
• Damage stone statues
• It damages metal and car finish
• Aquatic animal suffer from toxicity of
metal which leak due to acid rain
• Lakes of Norway, Sweden, Canada
become fishless
• Weakens trees
22. Control
• Control emission of sulfur dioxide
and Nitrogen dioxide
• Liming of lakes should be done to
restore pH of water
• Coating of inert polymer should be
given to water pipes and metal
objects
23. Photochemical smog
• Photochemical smog form by
interaction of hydrocarbon and
oxidant like NOx, CO, O3.
• It cause eye irritation, visibility
reduction and damage to crops.
• O + O2 --> O3
• NO + O --> NO3
24. Characterstic of phytochemical smog
• Peroxy acetyl nitrate (PAN) irritation in
lungs and cancer
• SO2 and H2S are readily oxidised to
sulphate in in smoggy atmosphere
• Nitric acid react with ammonia in smoggy
atmosphere to form ammonium nitrate
• Nitrogen oxides responsible for cancer and
cardiac disorder
• Ozone cause reduction in plant growth
• Occur in big cities like Mumbai, Delhi,
Chicago etc..
25. Control of air pollution
• Source control
• Adsorption
• Absorption
• condensation
• Baghouse
• Scrubbers
26. Baghouse Filters
• Vacuum cleaner
effect
• Particulate air pass
through the bags
to escape as clean
air through top
• 1.5-2.0 KPa
pressure drop
• Synthetic fabric
27. Venturi Scrubber
• Entrain particulate
matter in water
droplet
• Concurrent and
cross current flow
• Water flow from
bottom and
particle settle
down and clarified
water recirculated
• Reduce risk of
explosion
29. Defination
Water pollution
• Alteration in physical, chemical or
biological characterstic of water
making it unsuitable for designated
use in natural state.
• Any foreign material from natural or
other source that may contaminate
water supply and make it harmful for
life.
31. Domestic effuluents
Discharge of domestic waste
• Biodegradable
– Vegetables
– Waste food
– Paper waste
• Non Biodegradable
– Plastic
– Polythene bags
32. Industrial waste
Chemical, paper, pulp industries
produce waste material like heavy
metals cadmium lead mercury
• Lead
– Lead can enter water bodies from many
sources like mining, lead plumbing, lead
zinc batteries
• Mercury
– Methyl mercury is common for found in
aquatic environment
33. Sewage
• Fluid containing faecal matter, urine
and organic content in dissolve state
or disperse in solid state is called
sewage.
• Sewage disposal is serious problem
in big cities and major pollutant of
inland water, soil and ecosystem
34. Radioactive waste
• Waste water fron nuclear power
stations
• Waste generated during nuclear
wepon testing
• Research laboratories where
radioisotopes are used
• Waste from hospitals where
radioisotopes are used
35. Oil spills
• Exploring oil and gas at sea bed involve risk of marine
ecosystem
• Oil spillage during transportation
• The Exxon Valdez oil spill occurred in Prince William Sound,
Alaska, March 24, 1989, when Exxon Valdez, an oil tanker
struck and spilled 10.8 million US gallons (41,000 m3) of
crude oil over the next few days.
36. Thermal pollution
• Thermal power plant near river use water
for cooling purpose
• They recycle hot water into river leading
to thermal pollution
• Rise in temprature endanger aquatic
ecosystem
• Warm water does not have good oxygen
holding capicity
• Anaerobic condition generate foul gases
• Blue green algae grow in such condition
and produce toxins
37. Effects of water pollution
On Human
• Pathogens- Cholera, Hepatitis,
typhoid
• Toxic compounds- Heavy metals,
pesticides, cyanide
38. Effects of water pollution
