Environmental Pollution and prevention

Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.

  • 1. Made by: Deepanshu Kapoor Project Guide: Dr. Tanuja Nautiyal
  • 2. Man is one of the species who inhabit the earth . he is the only one who has interfered with various natural processes for use of both biological & physical resources to meet his multiple demands, man has polluted all the – lithosphere , hydrosphere & atmosphere. it is essential for us e realms of to know about environment & its pollution. •Primary & secondary pollutants •Acid rain •Ozone depletion •Green house effect •Noise pollution
  • 3. That which surrounds, the total sum of the condition of the surroundings within which an organism, or group, or an object,exists(including the natural as modified by human activity & the artificial).
  • 4. Our current atmosphere is a mixture of many different gases & suspended particles. It is almost same every where up to an altitude of 80 Kms.The atmosphere is divided in to 4 layers- Name of sphere or layer Height in Kms.

  • 6. Different Pollutants 1. Gaseous waste: Oxides of nitrogen,SO2,CO2,CO.Cl,Br,I,O3 & smog. 2. Complex organic chemicals: Benzene, ether. 3. Acid prop lets: H2SO4, HNO3 4. Agrochemicals: fertilizers, pesticides,herbicixles,fungicides, rematicides,weedicides,bectrecides etc. 5. Fluorides 6. Metals: Mercury,lead,Cd,Zn,Fe,Ni etc. 7. Solid wasre:Garbage,plastic etc. 8. Radioactive waste: Nuclear reacters,uranium,nuclear explosion. 9. Noise waste
  • 7. Secondary pollutants :These result from chemical reactions between two or more air components. Formation of secondary pollutants 2SO2+O2 2SO3 2SO3+H2O H2SO4 (Secondary pollutant) Primary Pollutants: Harmful chemical that directly enters the air as a result of human activity. These are deforestisation burning of fossil fuel industrialization warfare etc.

  • 9. CAUSES
  • 10. Environmental challenges Green house effect: Increasing global temperature. Scientists predicting that earth's temperature will increase by 3-40 C by year 2030 if the pollution continues to increase at the same pace. Ozone depletion: As ozone layer in the upper atmosphere absorbs incoming harmful ultraviolet radiation but it is now getting thinner & more UVs are reaching in to earth creating different disease like cancer& eye problems.
  • 11. Environmental challenges Photochemical smog: In 1952 London was covered by smog for 10 days .This smog was caused by fog, smoke, ash,& SO2 plus NO2.Sunlight played a great role in the formation of this smog .Though deaths occurring at that time were not directly attributed to the smog later statistics confirmed that 6,000 more people. Acid rain: is caused by oxides of nitrogen & sulphur.It increases acidity of soil & effects the growth of trees & plants. The majestic monument Taj Mahal in India is also affecting by this.

A Methane Carbon Dioxide Nitrous oxide Ozone EarthEarth Carbon Dioxide 50% Methane 18% Chlorofluoroc arbons 14% Ozone 12% Nitrous oxide 06% Green house gases in natural condition insulates the earth against extreme of temperature by limiting both incoming solar radiation & escape of reradiated heat in to space. This natural balance may be distorted by Green House Effect as gases such as carbon dioxide have built up in the atmosphere trapping more heat Contribution of different gases to cause green house effect
  • 14. The real greenhouse
  • 15. Ultraviolet rays from Sun The Ozone layer in stratosphere blocks these harmful UV rays Chlorofluorocarbons are entering in to atmosphere releasing chlorine. The chlorine than break down the ozone The chlorine released from CFCs break down the ozone molecule. chlorine ozone More ultraviolet radiations are reaching in to earths surface as there is a whole in ozone layer. Oxygen Whole in Ozone layer
  • 16. Noise pollution This era has rightly been called as the era of noise.because heavy industrialization we are exposed to a high level of noise all around us. Noise has become a very important stress factor in modern life.it leads many health hazards.Some of the sources of noise pollution are aircraft,automobiles,factories,loudspeakers& pop& Rock-n-Roll music in clubs . Noise produces following health problems- 1)Auditory fatigue 2)Deafness or impaired vision 3)Rise in blood pressure, pulse rate 4)Headache 5)Nausea 6)Disturbed sleep 7)Emotional disturbances

  • 28. We know that certain environmental conditions like air,water,& food are essential for man,s survival.apart from their availability their quality & quantity must be assured according to man,s natural & acquired capacity for sustenance progress in industrialization has brought environmental hazards such as air water & noise pollution.These have caused many health problems & diseases. As it has been said- we do not inherit the environment from our forefathers,we borrow it from future generation. Stockholm conference of 1972 proclaims that: The protection & improvement of human environment is a major issue which affects the well being of people & economic development throughout the world&it is duty of all governments & people to common efforts for the preservation & improvement of environment for the benefit of all people & their prosperity
